The Great War, occasionally referred to as the World War or the Second European War, was a large scale global conflict centered mostly in Europe and parts of Africa. Triggered by the French invasion of Belgium, along with the previous Russian invasion of Finland, Germany and its allies declared war on France and Russia.
The United Kingdom entered the war late in 1940 after a French warship bombarded the Channel Islands and occupied it soon after. By this point, the war was somewhat in favor of the Entente as France had occupied all lands east of the Rhine, and Russia had occupied all of the Baltic states and Ukraine. The U.S. had started supplying the British with aid after they declared war on France, however would remain hesitant on entering the war.
By 1941, after several American passenger and cargo ships were engaged by the French Navy, the United States declared war on France and Russia after subsequently being attacked by the Empire of Japan in the separate Pacific War. The situation in Europe had deteriorated significantly at this point. British forces were virtually annihilated after trying to take Dunkirk and launch an offensive into mainland Europe. German forces were pushed east of the Rhine and the Russians had seized Königsberg in November. The only successful front for the allies was in Italy, with an Austro-German offensive running successfully into Venice and liberating areas under Italian occupation.
