The British Army was called on to fight around the world, starting with campaigns in Europe in 1940. After the Dunkirk evacuation of Allied Forces from France (May–June 1940), the army fought in the Mediterranean and Middle East theatres, and in the Burma Campaign. After a series of setbacks, retreats and evacuations, the British Army and its Allies eventually gained the upper hand. This began with victory in the Tunisian Campaign in North Africa in May 1943, followed by Italy being forced to surrender after the invasions of Sicily and the Italian mainland in 1943. In 1944 the British Army returned to France and with its Allies drove the German Army back into Germany. Meanwhile, in East Asia the Japanese Army were driven back by the Allies from the Indian border into eastern Burma. In 1945 both the German and Japanese Armies were defeated and surrendered within months of each other.
