World War Two was fought in the Pacific and the Atlantic and Western Europe and Eastern Europe (and Africa) at the same time. So technically the war was fought on many fronts. In Europe it was a two front war on the West and East side. When you consider the USA the war was fought on two sides of the nation in two different oceans and different countries so they considered it a two front…
This is because, a two-front war is what caused the German Empire's loss in the first World War. He didn't want this happening again, but he was dumb enough to try invading the Soviet Union so that is exactly what he created. And he payed the price. Fighting a two-front war is a mistake, not only for Germany but ANY army. It is military suicide.
Depends on how you define 'front.' The Germans had an Eastern Front for the war with Russia, and the Western Front for the war with the Allies in Europe. And there were the fronts in Africa, and later a Southern Front when the Allies invaded Italy. The Americans fought in two primary theaters, the Atlantic and the Pacific.
After Germany declared war on Russia to help Austria-Hungary (who was attacked by Russia after they attacked Serbia), France made clear their intent to stand by their ally (Russia, obviously), so Germany declared war on them, too, planning to take them out then go after Russia to prevent a two-front war. Unluckily for Germany, Russia prepared pretty quickly so Germany had to send troops to the Eastern Front as well and fight a two-front war.
The term two-front war refers specifically to the European Theater of War. Up until D-Day, the only land front between the Axis and Allied powers was the eastern front between Russia and Germany. The strategy behind D-Day was to open a second front against the Germans and relieve pressure on the Russians. Allied leaders hoped a second front would put stress on Germany and strain their resources. After D-Day, Germany was essentially fighting agaisnt two…
What is a statement that summarizes the schliffen plan that Germany created to prepare for a two-front war?
Operation Overlord ("D-day attack"). Before that Germany fought on one front at a time: Poland 1939, Scandinavia 1940, France 1940, Balkan 1941, Soviet 1941-. Taking over the North African war from the Italians created a second front in 1941, but it wasn't a two-front war where the forces were enclosed. From 1944 it became a real two-front war, when allied forces advanced from both east and west.
