paragraph_text: The Western Allied invasion of Germany was coordinated by the Western Allies during the final months of hostilities in the European theatre of World War II. The Allied invasion of Germany started with the Western Allies crossing the Rhine River in March 1945 before fanning out and overrunning all of western Germany from the Baltic in the north to Austria in the south before the Germans surrendered on 8 May 1945. This is known as the ``Central Europe Campaign ''in United States military histories.

paragraph_text: Burgoyne's strategy to divide New England from the southern colonies had started well but slowed due to logistical problems. He won a small tactical victory over General Horatio Gates and the Continental Army in the September 19 Battle of Freeman's Farm at the cost of significant casualties. His gains were erased when he again attacked the Americans in the October 7 Battle of Bemis Heights and the Americans captured a portion of the British defenses. Burgoyne was therefore compelled to retreat, and his army was surrounded by the much larger American force at Saratoga, forcing him to surrender on October 17. News of Burgoyne's surrender was instrumental in formally bringing France into the war as an American ally, although it had previously given supplies, ammunition, and guns, notably the de Valliere cannon which played an important role in Saratoga. This battle also resulted in Spain joining France in the war against Britain.

paragraph_text: The war against Germany involved aid to Britain, her allies, and the Soviet Union, with the U.S. supplying munitions until it could ready an invasion force. U.S. forces were first tested to a limited degree in the North African Campaign and then employed more significantly with British Forces in Italy in 1943 -- 45, where U.S. forces, representing about a third of the Allied forces deployed, bogged down after Italy surrendered and the Germans took over. Finally the main invasion of France took place in June 1944, under General Dwight D. Eisenhower. Meanwhile, the U.S. Army Air Forces and the British Royal Air Force engaged in the area bombardment of German cities and systematically targeted German transportation links and synthetic oil plants, as it knocked out what was left of the Luftwaffe post Battle of Britain in 1944. With the Soviets unstoppable in the east, and the Allies unstoppable in the west, Germany was squeezed to death. Berlin fell to the Soviets in May 1945, and with Adolf Hitler dead, the Germans surrendered.

paragraph_text: However Italy's conquests were always heavily contested, both by various insurgencies (most prominently the Greek resistance and Yugoslav partisans) and Allied military forces, which waged the Battle of the Mediterranean throughout and beyond Italy's participation. Ultimately the Italian empire collapsed after disastrous defeats in the Eastern European and North African campaigns. In July 1943, following the Allied invasion of Sicily, Benito Mussolini was arrested by order of King Victor Emmanuel III, provoking a civil war. Italy's military outside of the peninsula itself collapsed, its occupied and annexed territories falling under German control. Italy surrendered to the Allies at the end of the Italian Campaign.

paragraph_text: After the great Battle of Dresden (26–27 August 1813), the Battle of Kulm took place here on 29–30 August, between the French Empire under Dominique Vandamme and an allied army of Austrians, Prussians, and Russians. The French were defeated and Vandamme surrendered with his army of 10,000 men. The heights above Kulm were the site of the Second Battle of Kulm, 17 September 1813.

paragraph_text: The final battles of the European Theatre of World War II as well as the German surrender to the Allies took place in late April and early May 1945.

paragraph_text: The Germans launched a surprise counter offensive, in the Battle of the Bulge in December 1944, which the Allies turned back in early 1945 after Eisenhower repositioned his armies and improved weather allowed the Air Force to engage. German defenses continued to deteriorate on both the eastern front with the Soviets and the western front with the Allies. The British wanted Berlin, but Eisenhower decided it would be a military mistake for him to attack Berlin, and said orders to that effect would have to be explicit. The British backed down, but then wanted Eisenhower to move into Czechoslovakia for political reasons. Washington refused to support Churchill's plan to use Eisenhower's army for political maneuvers against Moscow. The actual division of Germany followed the lines that Roosevelt, Churchill and Stalin had previously agreed upon. The Soviet Red Army captured Berlin in a very large-scale bloody battle, and the Germans finally surrendered on May 7, 1945.

paragraph_text: In Japan, 14 August is considered to be the day that the Pacific War ended. However, as Imperial Japan actually surrendered on 15 August, this day became known in the English-speaking countries as "V-J Day" (Victory in Japan). The formal Japanese Instrument of Surrender was signed on 2 September 1945, on the battleship USS Missouri, in Tokyo Bay. The surrender was accepted by General Douglas MacArthur as Supreme Commander for the Allied Powers, with representatives of several Allied nations, from a Japanese delegation led by Mamoru Shigemitsu and Yoshijiro Umezu.

paragraph_text: Hard-fought battles on the Japanese home islands of Iwo Jima, Okinawa, and others resulted in horrific casualties on both sides but finally produced a Japanese defeat. Of the 117,000 Japanese troops defending Okinawa, 94 percent died. Faced with the loss of most of their experienced pilots, the Japanese increased their use of kamikaze tactics in an attempt to create unacceptably high casualties for the Allies. The U.S. Navy proposed to force a Japanese surrender through a total naval blockade and air raids.

paragraph_text: The Battle of Luzon (Filipino: "Labanan sa Luzon"), fought 9 January – 15 August 1945, was a land battle of the Pacific Theater of Operations of World War II by the Allied forces of the U.S., its colony the Philippines, and allies against forces of the Empire of Japan. The battle resulted in a U.S. and Filipino victory. The Allies had taken control of all strategically and economically important locations of Luzon by March 1945, although pockets of Japanese resistance held out in the mountains until the unconditional surrender of Japan. While not the highest in U.S. casualties, it is the highest net casualty battle U.S. forces fought in World War II, with 192,000 to 205,000 Japanese combatants dead (mostly from starvation and disease), 10,000 American combatants killed, and between 120,000 and 140,000 Filipino civilians and combatants killed.

paragraph_text: The Armistice of Cassibile was an armistice signed on 3 September 1943 by Walter Bedell Smith and Giuseppe Castellano, and made public on 8 September, between the Kingdom of Italy and the Allies of World War II. It was signed at a conference of generals from both sides in an Allied military camp at Cassibile in Sicily, which had recently been occupied by the Allies. The armistice was approved by both King Victor Emmanuel III and Italian Prime Minister Pietro Badoglio. The armistice stipulated the surrender of Italy to the Allies.

paragraph_text: The war in Europe concluded with an invasion of Germany by the Western Allies and the Soviet Union, culminating in the capture of Berlin by Soviet troops, the suicide of Adolf Hitler and the subsequent German unconditional surrender on 8 May 1945. Following the Potsdam Declaration by the Allies on 26 July 1945 and the refusal of Japan to surrender under its terms, the United States dropped atomic bombs on the Japanese cities of Hiroshima and Nagasaki on 6 and 9 August respectively. With an invasion of the Japanese archipelago imminent, the possibility of additional atomic bombings and the Soviet invasion of Manchuria, Japan formally surrendered on 2 September 1945. Thus ended the war in Asia, cementing the total victory of the Allies.

paragraph_text: Ski troops were trained for the war, and battles were waged in mountainous areas such as the battle at Riva Ridge in Italy, where the American 10th Mountain Division encountered heavy resistance in February 1945. At the end of the war, a substantial amount of Nazi plunder was found stored in Austria, where Hitler had hoped to retreat as the war drew to a close. The salt mines surrounding the Altaussee area, where American troops found 75 kilos of gold coins stored in a single mine, were used to store looted art, jewels, and currency; vast quantities of looted art were found and returned to the owners.

paragraph_text: The Pacific War saw the Allies pitted against Japan, the latter briefly aided by Thailand and to a much lesser extent by the Axis allied Germany and Italy. The war culminated in the atomic bombings of Hiroshima and Nagasaki, and other large aerial bomb attacks by the Allies, accompanied by the Soviet declaration of war and invasion of Manchuria on 9 August 1945, resulting in the Japanese announcement of intent to surrender on 15 August 1945. The formal surrender of Japan ceremony took place aboard the battleship USS Missouri in Tokyo Bay on 2 September 1945. Japan's Shinto Emperor was forced to relinquish much of his authority and his divine status through the Shinto Directive in order to pave the way for extensive cultural and political reforms.

President Johnson formally declared the end of the war on August 20, 1866.

paragraph_text: Brigadier Dudley Wrangel Clarke ( – ) was an officer in the British Army, known as a pioneer of military deception operations during the Second World War. His ideas for combining fictional orders of battle, visual deception and double agents helped define Allied deception strategy during the war, for which he has been referred to as "the greatest British deceiver of WW2". Clarke was also instrumental in the founding of three famous military units, namely the British Commandos, the Special Air Service and the US Rangers.
