The British Army fought around the world, with campaigns in Norway, Belgium and France in 1940 and, after the collapse of both the latter countries, in Africa, the Mediterranean and Middle East and the Far East. After a series of setbacks, retreats and evacuations the British Army and its Allies eventually gained the upper hand. This started with victory over the Italian and German forces in the Tunisia Campaign. Italy was then forced to surrender after the invasion of Sicily and mainland Italy. Then in the last years of the war, the British Army, with its allies, returned to France, driving the German Army back into Germany and in the Far East forced the Japanese back from the Indian border into Burma. Both the Germans and Japanese were defeated by 1945, and surrendered within months of each other.
