In early 1968, American and allied forces fought the North Vietnamese Army in one of the most dramatic battles of the Vietnam War. For 77 days, two powerful NVA Divisions laid siege to the U.S. Marine Corps base at Khe Sahn.

Hitler's obsession with the Crimea was the source of fierce disagreements with his General staff, who, according to the Fuhrer, 'knew nothing about the economics of war'. So it was that the German 11th Army under Manstein broke through the Soviet lines in October 1941 - but this was only the beginning of a series of bloody battles that cost the Russians two whole armies. For his bombardment and capture of Sevastapol, Manstein was promoted to Field Marshal. However, the tide turned after the disastrous German defeats at Stalingrad and Kursk. Cut off and isolated in the Crimea, the Germans faced massive Russian attacks and Sevastapol surrendered - against Hitler's orders - in May 1944. Twelve German and Rumanian divisions were completely destroyed and 25,000 prisoners were taken.

Hitler's plan for the conquest of Russia called for a classic Blitzkrieg offensive, which would be pressed ruthlessly to its conclusion within the course of a single season's campaign.

The Nazi German Blitzkrieg's most astonishing triumph, sweeping into the heart of Paris in a few short days, and establishing Hitler's supremacy over Continental Europe.

The annihilation of an entire army amidst the charred and frozen ruins of Stalingrad was catastrophe for Nazi arms. Thereafter, the colossus of the Red Army was never to lose the initiative in the East.

In a classic naval engagement, the American and Japanese Navies squared off in the carrier-to-carrier Battle of Midway. Both sides knew that the victor would rule the Pacific for decades to come.

The battle for Okinawa, chosen to be the final springboard for an Allied invasion of Japan, claimed more American lives than any other battle in the Pacific campaign. The Japanese had constructed a formidable series of defences and were prepared to fight for every inch of the island's soil. The battle included a 700-plane Kamikaze raid against the US naval fleet. US casualties were estimated to be 49,000. Ultimately US forces took control of the island in June 1945 and in August, the atomic bombing of Hiroshima and Nagasaki brought the war against Japan to a dramatic end.

The convoys that sailed across the Atlantic Ocean bringing vital supplies to Britain faced one of the most deadly threats of the war. Hidden deep beneath the waves were German U-boats. This program follows the evolution of the Atlantic War, from the beginnings of the U-Boat war, to the "Happy Time" when German submarines almost brought Britain to her knees, to the eventual Allied triumph for control of the Atlantic sea-lanes. Also see the critical role that superior Allied technology played in winning the war and how British cryptographers successfully broke the German naval codes.

A vicious 14-week war between the Finns & the Russians ended in March 1940, the Finns finally surrendered a large part of its territory to the Soviet invaders. 500,000 were evacuated from the Karelian isthmus, the scene of the war's worst fighting. It was a hollow victory, as the Russians took a drubbing from the determined & resourceful Finns, who organised the defence of their country brilliantly. Nearly 1 million Russians lost their lives during the fighting & the weaknesses of the Red Army was exposed to the. Hitler was suitably encouraged, he was determined on the invasion & conquest of his erstwhile allied partner. Meanwhile, during the early months of the war, Hitler became increasingly aware of the potential threat of Norway & mounted the world's first airborne invasion there in February 1940. At the same time, German Forces invaded Denmark. Over the next few years, the horrors & intrigues of the Quisling government in Norway unfolded amidst determined Norwegian resistance.

This episode tells the tragic story of the "bridge too far" and the ill-fated Operation Market Garden--the Allied operation that was supposed to end World War II in 1944. Montgomery's rather fanciful conclusion that Market Garden was "90% successful" was hardly supported by the facts. The operation was an unmitigated failure.

This is the story of one of Second World War's most harrowing episodes. The 890 day siege of the Soviet Union's second city has come to epitomise the misery, suffering and savagery of the war on the Eastern Front. The city was not finally liberated by Soviet troops until 19th January 1944 - by that time 600,000 of its citizens had starved to death and 200,000 more had perished in the bombing. This is a brand new episode from the landmark television series 'Battlefield'. Featuring fascinating archive footage from all over the world the programme includes a review of the political and military situation before the battle, portraits of leaders and commanders, an explanation of weapons and tactics and the story of the battle itself. Vivid graphics place the battle into the context of the war as a whole.

The Allies were determined to take the war to Germany both to disrupt German war production and weaken civilian morale, and in retaliation for the Nazi terror bombing of England. The "Strategic Bombing Campaign" by the RAF and the USAAF was one of the most controversial campaigns of WWII and cost thousands of Allied lives and caused tens of thousands of civilian deaths.

Covering the leaders, the equipment, and the men, as well as the battles, it covers the period from the beginning of the war in Africa until the end where the Axis is expelled. The main battle covered here is the last battle of El Alamein.

Viet Cong guerrillas, backed by the North Vietnamese Army, staged a massive offensive against major cities and U.S. bases in January 1968, during the Tet holiday.

The campaign in Tunisia saw the battles that finally ended the brutal war in the desert. The arrival of the British 1st Army gave the Allies a six-to-one numerical advantage in troops and a fifteen-to one superiority in tanks, guns, and aircraft. The Allied blockade in the Mediterranean also began to bite, making the beleaguered Germans short of fuel, food, and ammunition. Eventually, all German troops in Tunisia surrendered.

Covering the entire Italian campaign including the battle of Monte Cassino.

Caen, perhaps the greatest major obstacle for the Allied advance inland after the landings in Normandy, 6 June 1944. Consequently it was a key objective for 3rd British Div. landing on Sword Beach. The Allies were unable to capture the strategically important city on D-Day in the teeth of armoured counter-attacks from 21st Panzer Div. Renewed attempts by 3rd Canadian Div. on 7-8 June were foiled by 12th SS Panzer Div. 'Hitlerjugend', as were 7th British Armoured Divs. thrusts towards the city on 11-14 June. On 25 June Operation 'Epsom' was launched to take Caen. Preceded by RAF Bomber Command attacks, further British & Canadian assaults on 4 July stalled before the whole of the city could be taken. On 7 July Operation 'Charnwood' forced the Germans to withdraw from northern Caen. Heavier bombardment opened Operation 'Goodwood' on 18 July, in the course of which the Canadians finally managed to liberate the rest of Caen, by now largely demolished after five weeks of intensive fighting.

What starts as a ripple becomes a wave, and with the United States involvement in Vietnam, it began as a contingent of U.S. "military advisors" after the attack at Dien Bien Phu. From there it turned into "non-official combat missions," and finally, after an unprovoked torpedo attack by a North Vietnamese patrol boat against the unsuspecting U.S. destroyer Maddox, it became "The Undeclared War."

When victory in North Africa seemed assured, Allied Planners turned their attention to Italy. The objective was to seize Rome, knock Italy out of the war and push north towards Austria.

Expanding its presence in 1966, the U.S. Army sets up patrols in the south to draw out Viet Cong guerrillas, but can't force a decisive battle. Included: veterans recall missions to uncover Viet Cong bases; the political climate in Saigon.

Viet Cong incursions in 1967 prompt the U.S. to reinforce key southern bases, unaware that the North Vietnamese were planning an all-out assault for early 1968. Included: combat footage; comments from veterans.

In the summer of 1943 more than 2,000,000 men and 6,000 tanks of the German and Soviet Armies faced each other near the Soviet city of Kursk. The ensuing battle was, to this day, the largest tank battle ever fought in history. It marked the last major offensive operation of German forces in the East and, combined with the Soviet victory at Stalingrad, was the decisive turning point on the Eastern Front.

Guadalcanal was the first major land battle of the Southern Pacific campaign. The island was considered key to the defence of eastern Australia and was the first step in the "march" up the Solomon Island chain to neutralize the key Japanese base at Rabaul, open up the road to the Philippines, and ultimately to Japan itself.

In August 1943 the Romanians--no doubt prompted by merciless Allied bombing--changed sides. Thereafter, events moved swiftly: the Russians soon captured the vital Ploesti oil fields, a huge loss to the German war effort, and within days the Soviets captured Bucharest. A nervous Bulgaria sued for peace with the Allies, but the Russians pushed on into Sofia. Despite German delaying tactics, Hungary fell next. In Yugoslavia the Germans held grimly on to Belgrade until October. The bloody mop-up fighting was left to the Soviets and lasted until the end of the war.
