How did the allies liberate Europe and defeat Germany?

The Allies liberated Europe and defeated Germany through a combination of strategic military operations, including the D-Day invasion of Normandy in June 1944, which established a crucial foothold in Western Europe. Coordinating efforts from the United States, the United Kingdom, and other nations, they launched a series of offensives that pushed German forces back on multiple fronts. Key battles, such as the liberation of Paris and the Battle of the Bulge, weakened German resistance, ultimately leading to their unconditional surrender in May 1945. The Allies also utilized aerial bombardments and cutting off supply lines to cripple Germany’s war capabilities.
