On April 25, 1915 Australian, British, New Zealand and French forces landed at the mouth of the Dardanelles to capture the Gallipoli peninsular and march on Constantinople. But the Ottoman defenders, including legendary officer Mustafa Kemal, held firm and the Battle of Gallipoli would last for 7 bloody months.

On March 3, 1918 the Central Powers (Germany, Austria-Hungary, Bulgaria, and the Ottoman Empire) and Bolshevik Russia signed the Treaty of Brest-Litovsk, ending the First World War on the Eastern Front. The terms were harsher than those the Germans offered in December, and much harsher than the later Treaty of Versailles. The Treaty of Brest-Litovsk was only in force until November 1918, when the Central Powers’ defeat nullified it. But it had a major impact inside and outside Russia.

On November 11 1918, the German delegation and the Allies reach an agreement for an armistice. At the 11th hour the guns go silent and the First World War is over, well at least the guns go silent but is it a peace already? Germany is struggling with revolution and civil war at home, the break up of the Austro-Hungarian Empire causes a lot of chaos. And in Romania, the men are taking up arms again.

The Germans start the biggest battle in history with an artillery barrage of over 1000 guns on a 20 km front. The Battle of Verdun is the first major German offensive since the Race to the Sea and Erich von Falkenhayn has high hopes to break through the French lines. Right before the offensive starts, the French are able to reinforce their defences, so they are barely able to hold the line. The French credo is: "lls ne passeront pas!" – they shall not pass!

The Austro-Hungarian army resembles a better militia after six months into the war. The defeats against Serbia and Russia and still under siege in Galicia - the forces are in dire straits. Many casualties, especially among the officers, mean that an effective warfare is impossible. And all this while the Russians are close to entering the Hungarian plains. On another front, the Rtussians are winning the battle of Sarikamish which ends in a disaster for the Ottoman Empire. On the Western Front, each side still tries to gain a decisive advantage.

By the spring of 1915, the Western Front had bogged down into trench warfare. Allied offensives tried to break the deadlock in spring and fall 1915. The fall offensives were among the bloodiest of the war. After unprecedented bloodletting and use of munitions, the Western Front was still locked in a stalemate at the end of 1915.

The Ottoman Empire has been on the retreat in the Middle East since the renewed British offensive in September and now, as the allies are threatening the Turkish heartland and also Constantinople, the Ottoman Empire calls for an armistice. The Armistice of Mudros is signed as the remaining Central Powers also struggle to keep their Empires together.

This week Russo-Romanian forces clash with the Central Power´s counteroffensive in the Second Battle of Oltuz. The failure of the Kerensky Offensive disheartens the Russian army and radicalizes the homefront. While the Bolsheviks were calling for "Peace, Bread and Land", the new commander of the Russian army Lavr Kornilov strives to become a strong authoritarian figure for the political right. And the Battle of Passchendaele reveals a scarred, broken battlefield of mud and destroyed equipment. Despair is everywhere.

The protests that emerged in Russia this week are growing stronger and the Tsar is increasingly isolated until even his generals are pushing for his abdication. And after 300 years of Romanov rule, Tsar Nicholai II abdicates and when his brother refuses to take up the throne, the dynasty is no more. Meanwhile in the Middle East, the British are taking Baghdad effectively seizing control over a large area.

Completely underestimating the Ottoman army at the Dardanelles, the British commanders decide to let the ANZACs take the Gallipoli peninsular as a gateway to the Bosporus and Constantinople. After the landing in ANZAC Cove and on Z Beach one thing comes clear though: Mustafa Kemal and his troops will fight for every inch of this piece of rock.

After more than 6 months of stalemate, the German Empire is playing two new cards to gain a decisive advantage. On the Eastern Front, the Germans use gas on a huge scale for the first time. While the attack fails, the foundation for gas warfare is laid. At the same time Kaiser Wilhelm II agrees to unrestricted submarine warfare – any ship can be sank at any time.

After the advances and retreats during the early weeks of war, the front is coming to a grinding hold after the Battle of the Aisne. The German Army is digging itself in on one side of the river and a new, horrible chapter of World War One begins: trench warfare. To be prepared for this new kind of war, the British Army is recruiting over 400.000 soldiers still believing that the war will be over by Christmas.

The German Army is so close to Paris that French soldiers are brought to the front by taxis. Together with the British Expeditionary Forces, the French are fighting the German advance near the Marne river. Meanwhile, the Austro-Hungarian army is retreating to the Carpathian Mountains after a catastrophic defeat against Russia with hundreds of thousands of casualties.

During their advance through Belgium, the German Army is committing atrocities against Belgian civilians - justified as response to resistance and sabotage against their advancement. The Austro-Hungarian Army is perpetrating massacres against the Serbian civilian population to retaliate against Serbian guerrilla warfare. At the Eastern Front, German generals Hindenburg and Ludendorff succeed in one of the most important battles of World War I: The Battle of Tannenberg.

In the early days of World War 1, warfare is still based on ideas and ideals of 19th century generals. The technological progress during industrialisation clashes with obsolete war tactics (Plan XVII). Tens of thousands of soldiers lose their lives in carnage at the Western Front. The French Army marches into battle in bright uniforms, where the German Army awaits them with machine guns. Artillery already shows how brutal and effective it's going to be during the rest of World War 1.

The commanders of the German army blame each other for the missing victories. Erich von Falkenhayn and Paul von Hindenburg both believe that they have the only solution to the problem. The German emperor Wilhelm II feels more and more excluded when it comes to military decisions. His soldiers become pieces on a chessboard and the war of the 20th century also takes its toll on some of the best commanders of World War 1. The situation at the Western Front stays unaltered: the French and Germans fight each other between the trenches. On the contrary, at the Eastern Front the Russians and the Germans are battling in a heavy fight.

Three months after the outbreak of the war, another world power enters the conflict: The Ottoman Empire. The Ottoman war minister Enver Pascha, a supporter of a new Turkish self confidence, wants to gain advantages for a future Turkey by declaring war. Meanwhile, another ship of the German East Asian Squadron is surprising the Royal Navy by sinking two of their ships near Coronel, Chile. Regardless, the battles on the Eastern Front, Western Front and in Serbia are continuing.

The fierce battle of Verdun is still going on and the initial surprise momentum of the German Army under Erich von Falkenhayn is lost. Battles for hill tops and forts turn into carnage where even the winning side is loosing too much men to go on. The Siege of Kut is growing ever more desperate as the there is virtually no food left for the British Army. And in all that Portugal is joining the war.

The morale of the Italian Army at the Isonzo Front is on an all time low. Catastrophic defeats against the Austrians, bad and broken equipment, unsanitary conditions, no supplies, no front leave and recreation for the soldiers. This week the first troops under Luigi Cardona are mutinying. At the same time the Entente is in real trouble against Bulgaria on the Macedonian Front and the evacuation of Gallipoli is still in the planning phase.

Serbia's last stand is over and the remaining forces and civilians have to leave their home country across the inhabitable trails of the Albanian Alps. So, a whole nation is on the run while their enemies celebrate their successful military operation. The German Army is gladly relocating the much needed troops to other fronts while they leave the Austrians and Bulgarians to deal with the new situation on the Balkans.

12 war zones were not enough for this global war and this week an often forgotten theatre of war opens in Libya. Local Arab tribesmen fight against the British in guerrilla war. As if the Italians did not have enough problems at the Isonzo Front where Luigi Cardona is still sending his men into certain death against the Austrian defences. The situation for the Serbs is grim too and on the Western Front the carnage continues unchanged.

After weeks of preparation the French and British Armies unleash a new offensive on the Western Front. Not only is it supposed to relieve pressure on the Russians on the Eastern Front but the Entente wants to achieve the decisive breakthrough. The French actually break through German trenches only to realise that they have a second line of trenches completely in tact right behind the first line. The British attack at Loos also turns into carnage even though the British use gas for the first time.

When the Germans take Vilnius, they set their plans of "germanizing" the whole area into motion. Erich Ludendorff believes that Courland and other areas near East Prussia are culturally German and that he's returning them to the Fatherland. While the Russian Army is now in a much better defensive position after their Great Retreat, civil unrest across the country is becoming a problem. Huge losses and the difficult supply situation are making it difficult to maintain order. At the same time, Bulgaria is mobilizing her troops, foreshadowing yet another front in this World War.

This week Indy dissects a contemporary source from autumn 1915 - the Hobart Mercury Newspaper from Australia. While the French and British prepare a new offensive on the Western Front, their Entente ally Russia is still suffering in the East when Germany is moving on the last big Russian city of Vilnius. Even though the propaganda says otherwise, the situation for the ANZACs in Gallipoli still looks grim.

This week Russia premieres her tactics of „Scorched Earth“. A new strategy of burning their own land is to avoid enemies profiting from their conquests. Russia had been retreating from the German and Austro-Hungarian armies for nearly three months now. Continuously losing huge areas of land and hundreds of thousands of men on the Eastern Front. As a consequence, millions of civilians had to flee their homes. At the same time allied troops at Gallipoli are weakened by infections and disease due to lack of hygiene and heat while Italy repeatedly failed to take out Austrian strongpoints.

Just a few weeks ago Austria-Hungary's military laid in shambles. But with German support from August von Mackensen and other German generals, the tide is turning on the Eastern Front. Even Lemberg can be conquered again and the Russians are still on their Big Retreat.

The war seems like a romantic novel this week: In the East the Russians are saved by Cossack Cavalry while August von Mackensen's artillery is plowing through Galicia. In the meantime, the British discover a German spy ring in London and the French gain a few miles in the west.

Ignoring the warnings and cruising carelessly slow the RMS Lusitania is hit by a torpedo of the German U-Boat U20. Almost 2000 people die during the sinking of the Lusitania. At the same time the German and Austro-Hungarian army start a combined surprise offensive in the Carpathians. The Gorlice-Tarnów Offensive is a huge success for German commander August von Mackensen.

he autumn rain turns the battlefields into muddy landscapes. Mud in which the soldiers are hardly able to dig trenches and in which no artillery gun will stand. The first change of seasons is proving to be a big new challenge for the armies in Europe. While at the time, the longest siege of the war is starting, we can also see the first major African battles of World War 1.

parked by the desperate state of the Austrians, the Russian army goes on the offensive. General Ivanov even tries to use his numerical superiority to make up for the German victories a few weeks ago. Meanwhile, the armies of the Western Front try to outflank each other as they race north to the sea. And in the North Sea itself, submarine warfare really gets going while in the air, we see airplanes used in large military operations for the first time in history.

This week, generals on three different fronts show that they are not able to realise their mistakes. Basra falls to the British, the quick victory at the Dardanelles is getting more and more unlikely and the Russians are loosing their advantage in the Carpathians. But not the commanders have to pay the price for their mistakes, the soldiers have to.

To break up the stalemate and get a decisive advantage, France and Great Britain open up yet another theatre of war in the Dardanelles. The plan is to seize the strait and open eventually open up the Bosporus in order to ship supplies to the Eastern and Balkan front. And so begins the naval bombardment of ottoman forts as prelude to a big offensive which will we know to today as Gallipoli.

This week, well over 1 million soldiers are on the advance everywhere in Europe. General Hindenburgs tries to beat the Russians once and for all at the Masurian Lakes. Austria-Hungary is fighting the Russians with German support in the Carpathian mountains and on the Western Front the Champagne offensive is still going.

The Champagne offensive is still going on the Western Front without any side gaining a decisive advantage. In the Caucasus, Enver Pasha is showing how far he's willing to go to achieve his goals. Against his military advisors’ recommendations, he decides to send more and more troops to Sarikamish. Without supplies and with temperatures constantly below -20 degrees, thousands of Ottoman soldiers freeze to death before even reaching the frontline. When the Russians finally encircle the Ottoman troops, defeat is inevitable.

Right before Christmas the allied powers begin the Champagne offensive, which will last several months. In snow, mud,and under horrible living conditions not only the soldiers suffer. The images of a war fought with honour and glory are finally over as even the white flag is used for ambushes now. Far away in the mountains of the Caucasus, Russia and the Ottoman Empire are fighting a grim battle, too, in which many soldiers die during interminable marches in the snow wearing summer uniforms.

German admiral Franz von Hipper reluctantly carries out his orders to bomb British costal towns. And indeed, this attempt to intimidate British civilians only unites them. British propaganda gets another opportunity to portray Germans as bloodthirsty and brutal. Meanwhile, the French start a new offensive near Vimy on the Western Front.

Four months after the outbreak of the war, a new objective develops: the fight for the most valuable resources. The modern warfare and its war machines need one thing more than anything: Oil, iron, steel or cole can be a matter of life and death. The British advance into the Ottoman Empire and conquer the city Basra. Their goal is to secure their drilling facilities at the Arab Gulf. Meanwhile, the situation at the front is gridlocked, especially in the trenches on the Western Front.

By the late 19th century the US stretched from the Atlantic to the Pacific to the Arctic. From the 1890s though, a new wave of American expansion began that resulted in a vast overseas empire including the Philippines, Cuba, Haiti, Panama, Nicaragua, and more.

The first four months of 1915 witnessed a titanic struggle on the Eastern Front, in East Prussia, the Carpathians, Bukovina, and at Przemysl. Both sides suffered staggering casualties that surpass those of the Somme or Verdun the following year. Ironically, the Austro-Hungarians lost far more men trying to save Przemysl than there were in the fortress.

More than 13 million men served in the German army during the First World War. Most wrote letters home, some kept diaries, and some wrote memoirs if they survived. But over a century later, it’s rare to have a window into the everyday thoughts and feelings of one man, a time capsule of the experience of one of those 13 million.

The armistice of November 11, 1918 ended the fighting between the Great Powers in the first world war. But for much of Europe and the Middle East, the armistice nor the peace treaties that followed failed to achieve a stable peace. The collapse of the German, Austro-Hungarian, Ottoman, and Russian Empires left an unstable power vacuum and brought opportunities for political violence. The so-called Big Four victorious powers at the Paris Peace Conference – the Americans, British, French, and Italians – didn’t have the power or political will to impose peace everywhere. The result was a series of bitter regional wars that would plunge millions into ruin, radically reshape the map, and still fire debates today.

Both the Entente and the Central Powers didn't achieve a breakthrough in 1916. 1917 would bring dramatic changes on all fronts with new weapons, tactics, two Russian Revolutions and more.

In the late 19th and early 20th century the great European powers were entangled in a series of escalating crises and wars. Each successive crisis brought the world one step closer to the outbreak of the First World War.

By April 1915, the Western Front was mired in trench warfare. Germany’s new Chief of Staff, General Erich von Falkenhayn, didn’t think his army could break the deadlock, and Germany needed to help struggling Austro-Hungarian forces in the East. Before the Germans turned against Russia though, they decided to attack in the West to keep the Allies off balance. They chose to strike at the vulnerable Ypres Salient – and they would support the coming offensive with a weapon their enemies had never seen.

In early 1917, the United States was still neutral in the First World War. Meanwhile, German leaders were getting desperate – if they couldn’t find a way to break the war of attrition on the Western Front, the Allies would probably defeat them. The result was multiple gambles that staked everything on a quick victory with the risk of drawing the US into the war.

In the last years of the 19th century, tension was building in the Caribbean. American newspapers were filled with grisly reports of Spanish atrocities against the people of Cuba struggling for independence. US businessmen and expansionist politicians also saw practical opportunities in Spain’s struggles: great power status and an empire for the United States. It’s the Spanish-American War.

In May 1915, the Central Powers launched one of the greatest offensive operations of the First World War. The armies of Germany and Austria-Hungary planned to smash their way through Russia lines and tip the strategic balance in their favor. The result was one of the biggest and bloodiest campaigns of the war, known today as the Great Russian Retreat.

Unrest within the German Empire is spreading, resentment against the war, the hunger and the elites is turning into revolutionary action and with a mutiny in Kiel the wheels begin to turn quickly. Austria signs an armistice, the Macedonian Front collapses, Romania might enter the war again and the new German political leaders send a delegation through the lines in France. Their goal: An Armistice.

After the Battle of the Piave, the Italian front had been relatively quiet and stable. But just as unrest and instablity spread through the Austro-Hungarian Empire, the Italian Army and its allies attack along the whole front. From Monte Grappa and across the Piave, the Austro-Hungarians are caught off guard.

As the Germans are retreating further and further during the Battle of the Selle, Erich Ludendorff – the German Quartermaster General, one half of Germany's military dictatorship and mastermind behind the last big German offensive in spring 1918 – resigns under pressure by the Kaiser and the Reichstag. The German upper class realizes that their days might be numbered if the war continues in the current form and Austria-Hungary's Emperor Karl has the same epiphany.

The Hindenburg Line or Siegfriedstellung is the backbone of the German defenses on the Western Front and this week 100 years ago, the Allies break through during the Battle of St. Quentin Canal. At the same time, the political fallout within Germany continues and the Allied Army of the Orient continues its offensive on the Macedonian Front.

While Bulgaria signs the Armistice of Salonika and effectively exits the war as the first of the Central Powers, the Hindenburg Line is broken on the Western Front. It dawns among the German leadership, that an armistice is necessary and in a desperate attempt to secure a more favourable position at the negotiations table, the Kaiser agrees to a "revolution from the top" that gives more political saying to the Reichstag.

This week, the biggest American military operation in history kicks off with 1.2 million American soldiers trying to take the Krimhilde Stellung. At the same time the Army of the Orient advances into Bulgaria and the Ottoman 7th and 8th armies collapse in Palestine.

In a turbulent week of the First World War, the Allies break through at the Macedonian Front during the Battle of Vadar and in Palestine during the Battle for Palestine. At the same time, the Ottoman defeats the last defenders of Baku.

The American First Army joins the fray on the Western Front with the Battle of Saint-Mihiel. All along the Western Front, the Allies are attacking or planning new attacks. The situation for the Germans looks dire even as the first war reparations from Russia arrive.

After an almost successful attempt on Lenin's live, the Tscheka under Felix Dzerzhinsky responds with a terror campaign to consolidate Soviet power through fear. At the same time, a supposed Allied plot is unveiled that would get Russia back into the war.

As the German Army withdraws along the Western Front, the Entente prepares for ever more offensives. This includes the newly founded American First Army which will have the task to attack the Germans in the Meuse-Argonnes area.

With the recent "Black Day of the German Army" and the success of the new strategy of Allied attacks along the Western Front and with the renewed offensives in Palestine, British Commander Sir Douglas Haig is confident the war can be won by the end of the year. Entente Generalissimo Ferdinand Foch is a bit more cautious but also thinks the war can be won by 1919.

As the Battle of Amiens is coming to an end, the Germans are desperately trying to stem the Allied advance and fortify new positions. But morale is crumbling and German High Command is running out of time to find a new strategy. Meanwhile in Russia, the struggle between Bolsheviks and Social Revolutionaries reaches a violent climax. The Dunsterforce finally arrives in Baku to help defend the city from the Ottoman advance. But this is not the mighty British force the inhabitants had hoped for. Does Ludendorff choose to abandon all the gains the German army made over the spring? And what about the attack on the Wookies? Find out this and more in the new episode of The Great War.

In the trenches on the Western Front and in the mud on the Eastern Front, hundreds of thousands of soldiers die and with them dies the illusion of a short war. After heavy casualties, the armies are adapting to a longer conflict and are looking for new recruits. To convince them to fight they are taking advantage of national minorities and their hope of equal rights and self-determination.

Modern war already took place in the sky and under water but the waring nations also wanted to gain an advantage in the trenches. So this week, we see the first use of another merciless invention on the battlefield: the flame thrower. The battles on the Western Front, in the Carpathian's and near the Dardanelles continued nonetheless.

French general Joseph Joffre is stuck in a dilemma: the Champagne offensive has been going on for weeks now - without any of the expected results. Should he dig in and tolerate the enemy on French soil? Or should his soldiers continue to run up against the impenetrable German defences? Meanwhile, South African troops attack German South West Africa and in London, Winston Churchill's plan for an invasion of the Dardanelles has been approved.

The British Expeditionary Forces are starting their first major offensive since the beginning of trench warfare. Near Neuve-Chapelle they attack the Germans and try to "bite and hold" their position. This battle will be the blueprint for future British offensives. On the Balkan, Serbia is facing a different enemy: Typhus. The catastrophic sanitary conditions enable the disease to spread across the whole country.

The situation for the Italian soldiers was dire during the winter battles, but even though Luigi "The Generalissimo" Cadorna maintained a tight grip on the strategy used, the equipment of the Italian soldiers was greatly improved. At the same time, the Russians were advancing on Erzurum in the Turkish Caucasus and war at sea counted a few more casualties on all sides.

The sinking of the Lusitania is still causing diplomatic tensions between Germany and the USA. While the Germans insist they were forced by the British blockade to adopt unrestricted submarine warfare, the Americans think otherwise. In the meantime the Russian Army is taking Erzurum in the Caucasus and the big offensive at Verdun is delayed for a week.

This week 100 years ago there was talk about peace between the great waring nations. But even after millions of casualties, starving people at home and more escalation on the horizon, the situation didn't seem bad enough for one of them to give in on their demands. At the same time, the fighting in Romania continues and the political situation in Russia becomes evermore dire.

After more than six months of war, the first big mutiny breaks out in Singapore. The endless battles in which big powers sacrifice thousands of soldiers are leading to an organised resistance for the first time. Indian troops refuse to board a ship because they don't want to fight other muslims in the Middle East. Meanwhile, Paul von Hindenburg encircles the Russians on the Eastern Front and they almost suffer a defeat as they did in Tannenberg 1914.

The Ottoman Navy is finally able to fend off the Russian and Royal Navies in the Dardanelles, Bulgaria is considering joining the Central Powers, Austria-Hungary is fighting off the Russians in Galicia and the German start a new offensive in the Baltics. All in one busy week of spring 1915.

After the assassination of Franz Ferdinand, Austria-Hungary is determined to put a lid on Serbia once and for all. Germany wanted to go to war with Russia sooner than later, because it was a afraid of a strong Tsar Nicholas II. In the first episode, Indy explains how the various European conflicts spiralled into a world war.

After defeating the Russian Army in the early weeks of the war, the German and Austrian generals hope to push the Russians back with combined forces. But, like Napoleon 100 years earlier, they underestimate their enemy and his tactics and so the tides are turning on the Eastern Front. On the Western Front, the last frontline gaps are closed and the British army is entering a small town called Ypres, which will eventually be the symbol for the carnage in Flanders for the next four years.

The first weeks of war already took hundreds of thousands of lives and the daily struggle to survive in the trenches on the Western Front has nothing to do with the promised glory. Back home, propaganda is already working and grotesquely distorting the public's opinion about the war. While the British civilians feared a German invasion, some of the leading German scientists and intellectuals published the "Manifesto Of The 93" in which they rallied for solidarity with the Germans

The German army dug in at the Western Front and waited for the next Russian attack at the Eastern Front. Even though the Germans outnumbered their opponents, they barely stood a chance against machine guns in No Man's Land. They realize: to defend a position is a lot easier than to attack and conquer. Especially while fighting near Ypres. At the Eastern Front, things are going better for Chief of Staff Ludendorff: he breaks through outstretched Siberian lines. At the same time, Russian soldiers are faced with a new enemy and start the Bergmann Offensive in today's East-Turkey.

Konrad von Hötzendorf has to prevent the Russian army from entering the Hungarian plains. He starts a huge offensive in the Carpathian Mountains - in mid winter. He also wants to demonstrate his power to Italy and Romania who are considering entering the war for the Entente. Meanwhile, in the North Sea the first Battle of Dogger Bank takes place which leads to the sinking of the German ship SMS Blücher.

The first few days of war were a combination of failed organisation and chaos. The Austro-Hungarian supreme command lacks combat experience, and their irrational actions in Serbia are causing turmoil among the Germans. At the Eastern and Western Front, early signs of problems can be seen, too, which the armies will pay a terrible price for, in the upcoming weeks.

Austria-Hungary starts the bombardment of Belgrade. What follows is a deployment race of armies between all major powers in Europe. Nobody wants to be unprepared in case of an attack. Germany is implementing the Schlieffen-Plan. The idea is to avoid a two front war by conquering Paris via Belgium. After that the full attention would be diverted to Russia. One thing gets clear in the first days at the Western Front: This war is going to be different - this was modern warfare.

While the Germans on the Western Front are very close to reaching Paris, the Eastern Front proves to become a disastrous failure for the Austro-Hungarian forces. Conrad von Hötzendorf overestimated his skills and the strength of his troops. And after his too complicated plan in Galicia failed, the town of Lemberg falls into the hands of the Russians. Meanwhile, the war starts spreading into Asia, as Japan is besieging Tsingtao and New Zealand conquers German Samoa.

After some heavy casualties during the first months of war, the armies had to look for new recruits. While Great Britain undertook soldiers in military service to fill up their ranks, Germany was relying on reservists and inexperienced recruits. This fatal German mix was sent against smaller, but much more experienced British and French troops. The resulting carnage had no military effect, but was later on idolized by the German propaganda and is today known as the "Kindermord" (child murder) or Massacre of the Innocent.

During the first week of December, Austria manages to capture Belgrade. Thereby Austria is the first nation to achieve one of its war aims. The victorious Austrians are joyful, but the Serbs strike back and the Austrian euphoria takes a sudden end. Meanwhile, the Russians fight against the German and Austrian troops in front of Cracow. But the Austrians are able to stop the Russian offensive and achieve yet another victory.

Near the far away Falkland Islands the story of the German East Asia Squadron is coming to an end: in a naval battle nearly the entire squadron is sunk and Maximilian von Spee dies together with over 2000 German seamen. Meanwhile, the war of attrition is still going on in Europe and Austria-Hungary has to learn that their conquest of Belgrade is not putting a lid on the Serbian resistance.

For a decisive advantage on the Western Front, the military commanders of both sides are trying to use technological advances. And so this week, German Zeppelins are flying their first air raids on English towns. Winston Churchill is outlining his ideas for what would later become the tank. Meanwhile at the Western Front, the soldier Adolf Hitler is thinking about how this war is going to continue.

Even though the Entente offensive near Constantinople didn't really take off yet, the allied powers were already dreaming about splitting up the Ottoman Empire between themselves - and even promised territory to other nations. In the meantime, Austria-Hungary started its third offensive in the Carpathians to free the besieged army in Galicia.

The generals at the Western Front are slowly starting to adapt to the modern war. The battle of Neuve-Chappelle will be a blueprint for future operations and further improvements are supposed to finally bring the decisive advantage. In the meantime, after 133 days, the fortress of Przemyśl capitulates - the longest siege of World War 1.

The leaders of the Ottoman Empire are looking for a scapegoat after their collosal defeat in the Caucasian Mountains a few month earlier. They start the systematic relocation and disarm Armenian troops among their ranks to end all calls for Armenian independence. Today's estimates place the death toll of the genocide up till 1.5 million men, women and children.

fter experiments on the Eastern Front, the German Army is using poison gas for the first time on the Western Front. At the beginning of the 2nd Battle of Ypres, the wind blows in a favourable direction; the wide spread use of chlorine gas has a devastating effect on the French troops. Even the Germans are surprised by it. The incredible sacrifice of the Canadian troops make it possible to defend Hill 60 in the end.

The 2nd Battle of Ypres is still going but no side can gain a decisive advantage. The main reason on the British side is a lack of artillery ammunition. Even the delivered shells are not working correctly. But even the German supply lines are stretched thin. At the same time German South-West Africa falls to South African troops under Louis Botha.

The big success of the Gallipoli Campaign never came, thousands of soldiers died and so Winston Churchill is forced to resign. At the same time August von Mackensen is pushing back the Russians and forcing them to hide in Przemyśl fortress - the same fortress they just conquered from the Austro-Hungarians a few weeks earlier.

After the defeats of Austria-Hungary against Russia, Italy is seeing her chance to grab disputed territories from them. Even though they are not prepared for a full scale war economically or militarily, the declare war against the Central Powers. So, just one month after the landing at Gallipoli, yet another front is opened in Europe. Meanwhile the Russians are still on the run from August von Mackensen and in Gallipoli the fighting stops to collect the dead.

When Przemysl falls for the 2nd time and when the British and ANZAC troops fail at Gallipoli again, one thing becomes clear: Artillery is the key for future battles. August von Mackensen had used it with great success at the Gorlice-Tarnow-Offensive and the French even diverted one million men to shell factories. Meanwhile German Zeppelins bombed London and the US sent submarines for aid.

Reginald Warneford is important to Britain's war effort. Not just because he shot down a German zeppelin, but because he is made a hero in times when heroes are needed. He receives a Victoria Cross soon after his victory because the commanders know about the average life span of pilots in World War 1. Meanwhile, the Austro-Hungarian army digs into the alpine rocks to fend of the Italian Attackers and Gallipoli continues to be a butchery without any progress.

Two months after landing in Gallipoli the fight has become a trench warfare. In Mesopotamia British troops were losing the optimism, they had felt just a few weeks ago. The change of seasons brought more heat, turning the weather from bearable to excruciating. Heat became a deadly foe. While the German crown prince Wilhelm unsuccessfully tried to break through the Western front in the Ardennes, the Austro-German force managed to drive back the Russians in the East.

The Great Retreat of the Russians during the last weeks has shown one thing: Artillery is the key to success. More specifically, a new kind of artillery tactic called the artillery barrage which focuses shelling on one part of the front. August von Mackensen had actually stolen this approach from John French. The Entente tried to use it on the Western Front a few months earlier without the expected breakthrough.

The German-Austrian offensive on the Eastern Front had undone all of Russia's territorial gains in the last weeks. Lemberg had fallen and the German troops were at the gates of Warsaw. The Russian casualties were in the millions, especially equipment and officers were becoming scarce. And exactly now, the German high command (OHL) prepared an all-out offensive along the entire frontline. At the same time in Gallipoli, one failure followed the other. How long would the Entente be able to continue this exercise in butchery?

After Russia's Great Retreat and the defeat on the Eastern Front, the Russian Army is demoralized and even revolution is in the air. Germany is fanning the revolutionary flames by sending Bolshevik prisoners of war back to Russia - equipped with money to support the Bolshevik cause. Meanwhile, the the war is continuing on the Western Front. Even small skirmishes are turning into atrocious battles with little gain for either side. A great offensive is not in sight.

After the Russian defeats on the Eastern Front, Warsaw falls. The first time in over 100 years a new foreign power occupies the city. The German onslaught in the East seems to be unstoppable. Also on the Western Front the Germans are causing havoc with the new Fokker-Eindecker planes which start the so called Fokker Scourge. The British pilots even start to call their airplanes Fokker-Fodder. At the same time, the battle in Gallipoli continues with ever more troops landing while neither the Ottomans nor the ANZAC troops can gain any advantage.

Another 20.000 soldiers fresh from the barracks are supposed to turn the tide at Gallipoli. But Mustafa Kemal is an Ottoman commander to be reckoned with. With a tactical ruse and the right timing, he surprises the inexperienced ANZAC recruits with a bayonet charge. As the sand of Chunuk Bair turns red, one thing is clear, Gallipoli is still not taken. On the Eastern Front the Germans lay siege on Kovno and are about to encircle the Russian troops near Brest-Litovsk. The German offensive on the Western Front is not nearly as successful though.

he Entente was in desperate need of American supplies and so the German submarine campaign in the Atlantic was a real problem. The British started to run false flag operations with so called Q-Ships to hunt down U-Boats which lead to the so called Baralong Incident this week. In the meantime, Russia was standing up against the wall as the fortresses of Kovno and Novogeorgievsk were falling to the Germans leading to a catastrophic loss in men, equipment and supplies.

Peter Hart described the state of the Gallipoli campaign in 1915 as "lunatic persistence in the face of the obvious" - and the Battle of Hill 60 proved just that. Outgunned and with a lack of artillery support, the battle was one of the bloodiest days on the peninsular near Constantinople. The Ottoman capital was still out of reach for the Entente to capture. Meanwhile, the war spread to the Indian border region and on the Western and Eastern Front the carnage continued in the air and on ground.

The Western Front has been relatively quiet the whole summer while the Russians were on their Big Retreat. The French and British generals have been busy trying to find a new strategy to overcome the stalemate. The Germans weren't sitting idle while awaiting the next big French offensive, they fortified their positions even using concrete. At the same time in the East, Tsar Nicholas II personally takes over military command and fires Grand Duke Nicholas Nikolaevich for the catastrophic casualties the Russian Army faced this summer. But his timing could not be worse.

While the Socialist movement gathers in Switzerland and calls for peace on the Western Front, on the Eastern Front and the Balkans the signs are set for the opposite: An escalation with new offensives. The French and British want to attack near Artois and in the Champagne, Germany wants to finish the war weary Russian Army. At the same time Bulgaria agrees to attack Serbia within the next 30 days. Even in London the war can still be felt when German Zeppelins continue to drop bombs on the British capital.

The Central Powers want to open a direct supply connection between Berlin and Constantinople. So, they start a new offensive on Serbia to defeat them once and for all. It's an open secret that Serbias neighbour Bulgaria will soon join the war so the Serbians are in dire need of help. With no other option, the Entente lands troops in Salonika, Greece. The whole situation on the Balkans is sprialing out of controle once more. Meanwhile the new offensives on the Western Front continue while the Eastern Front cools down.

By the numbers the Battle of Loos was a defeat for the British Army but they learned valuable lessons for the future on the Western Front. The creeping artillery barrage is used for the first time successfully and it is apparent that assault tactics have to be rethought completely. On the Balkans, Bulgaria officially declares war on Serbia and joins the Central Powers Germany, Austria-Hungary and the Ottoman Empire. On the same day they invade Serbia which is now in real trouble.

Edith Cavell was a British nurse serving in a nursing school in occupied Belgium. She was executed by the Germans for treason and espionage in Brussels. Her death and the surrounding atrocity propaganda caused a public outcry all over the world. At the same time the First World War continued like never before. The Third Battle of the Isonzo didn't bring a decision between Austria-Hungary and Italy, in Gallipoli the troops were slowly withdrawn and the the Champagne offensive of the French army was still in full swing.

After the Great Retreat during the summer, the Russians are finally able to fight back the Germans at Dvinsk. With a new type of trench warfare, they are able to render August von Mackensen's artillery useless and only take on small numbers of Germans at the same time. The German army is successful in Serbia though and so the situation for the Serbs looks grim. Meanwhile Benito Mussolini writes in his diary that the worst enemy is not Austria-Hungary, but lice. All of the soldiers and generals know one thing: Winter is coming.

For the third time the Italians had tried to conquer the Austrian positions at the Isonzo front and for the third time they had failed. And like the other defeats before, the Third Battle of the Isonzo came with an extreme amount of casualties due to the difficult terrain in the Alps. At the same time, Lord Kitchener visits the front in Gallipoli and realises that evacuation is the only logical decision to make. On the Western Front, the French had suffered well over 200.000 casualties during the autumn offensives at Artois and in the Champagne.

erbia's Army cannot hold out much longer against the invasion of the Central Powers. Germany, Austria-Hungary and Bulgaria are relentlessly pushing forward through the Balkan country. The French are trying to help from the south but a river proves to be an obstacle they cannot overcome. In the Alps, the 4th Battle of the Isonzo starts one week after the 3rd had failed and in West Africa, the Battle of Banjo takes place as one of the last battles of the German colony Kamerun (Cameroon).

Far away from the Western Front, the British Indian Army gets intro trouble in Mesopotamia against the Ottoman Empire. In the Alps, the Fourth Battle of the Isonzo is proving just as disastrous to the Italians the other three before. And in Serbia the situation is getting darker and darker as Nis is falling to the Central Powers. All while the flying aces of World War 1 are fighting it out in the skies over the Western Front.

Serbia is breaking under the pressure of the Central Power invasion and the last troops and civilians flee through the Alps. The final decision to evacuate Gallipoli is made and the British Indian Army gets under siege in the town of Kut Al Amara in Mesopotamia. The end of 1915 certainly looked grim for the Entente. The morale in Italy was also at a low point after the Fourth Battle of the Isonzo river ended like the three before.

While the Western and Eastern Front freeze over and the armies there have to fight the harsh conditions as much as the fight the enemy, the evacuation of Gallipoli is set into motion. After months of stalemate, the disease ridden offensive is finally called off. Unlike the rest of the operations there, the evacuation is actually following a thorough plan.

1915 was a year for the Central Powers except on the Western Front where the stalemate continues. But plans are being made on both sides to gain an advantage. Preparations for huge offensives are on the way and one French fortress is the focus of the German Army: Verdun.

1915 was a year in favour of the Central Powers. But in early 1916, the Russians, British and French were sending more fresh troops into battle than ever before – and better equipped too. French General Joseph Joffre was confident that a huge combined offensive at the Somme in summer would turn the tide. But German Chief of Staff Erich von Falkenhayn had his own plans to bleed the French dry at Verdun.

It already started around Christmas but this week the evacuation of Gallipoli is complete. While the evacuation was a success, the overall defeat is inarguable for the British. On top of that the Ottomans can now send 40.000 soldiers to the siege of Kut in Mesopotamia where the British are still awaiting relieve. At the same time the Austro-Hungarian Army starts its invasion of Montenegro and the Western Front is still quietly awaiting the offensive at Verdun.

The Russians try to take Czernowitz, the Capital of Austrian Bukovina but thousands upon thousands of Russians were killed in action. While in Montenegro, Austro-Hungarian troops under commander in chief Franz Conrad von Hotzendorf take control of the Balkan state of Montenegro. A relief force led by Lieutenant-General Fenton Aylmer had to return to base after a big loss against the Turks, while in South Cameroon, so the Germans retire into Spanish territory.

Even though Britain went to war over the violation of the Belgian neutrality by the Germans, the neutrality of Greece seems to be of no concern to the Entente. The military presence on Corfu and Salonika is growing and growing. And even though there is no fighting there, the soldiers have to suffer since general Malaria is taking his toll. In the week of the Kaiser's birthday, the diplomatic tensions between the USA and Germany are increasing and on the Western Front Trench Foot is becoming a real problem.

The preparations for the huge German offensive at Verdun are almost complete. Thousands of artillery pieces are moved, millions shells brought to the front. Erich von Falkenhayn would soon unleash is offensive on the Western Front. At the same time, Russia headed south to the Caucasus once more in search for a desperately needed victory against the Ottomans.

The fierce Battle of Verdun continues but as the Germans under Crown prince Wilhelm push harder and harder, the German casualties begin to rise to the same levels as the French. The French Army is only kept alive through the sacred road which brings men to the front without a pause. One French soldier that gets captured around Verdun, is Charles De Gaulle. At the same time, on the almost forgotten Libyan Front South African cavalry saves the day like in the glorious past of the British Army.

This war was supposed to be over by Christmas 1914. Now, as 1917 dawned, the world still knew 10 active theatres of war around the globe: Western Front, Italian Front, Eastern Front, Macedonian Front, Caucasus Front, Persian Front, Libyan Front, Palestine, Mesopotamia and German East Africa - and still there was no end in sight, no quick victory to be had for any side.

The winter of 1916/1917 is the harshest one so far in the war. Nowhere do the soldiers suffer from these extreme conditions than on the Italian Front in the Dolomites. The fighting there is fierce already but the cold, avalanches and height make it even more brutal. After the failed peace negotiations, the cry for ethnic self determination can still be heard all around the world. And German foreign secretary Arthur Zimmermann sends a fateful telegram to Mexico that is today remembered as the Zimmermann-Telegram.

Germany is about to unleash unrestricted submarine warfare again which might draw the United States into the conflict - but the Germans are not worried. The German Kaiser is instigating with his sister in Greece and Nivelle has big plans for a decisive battle in spring.
