he over extended his forces and tried to conquer the worlds largest country, Russia. He also failed to defeat Britain or at least make peace with the British government. He sent troops to North Africa and into southern Europe to bail out Greece. Hitler refused to listen to his generals who wanted to regroup and reorganize their forces. Instead he wasted thousands of troops trying to take Stalingrad which resulted in the annihilation of an entire army.

Then the allies invaded France and opened a second front. Germany's armies were overextended again and now had to face a 2 front war. Germany was being bombed day and night by the Allied and Soviet air forces. The Allies and Soviets invaded Germany and captured thousands of towns and cities and defeated thousands of German troops and destroyed their weapons such has tanks, artillery and armored vehicles. The Americans and Russians met at the Elbe river on April 25 1945 effectively cutting Germany in half. In the West the allies cut off the remaining German forces from Berlin who surrendered. The Russians invaded Eastern Germany and captured Berlin. Hitler chose to kill himself and his new wife and even his dog. Learning of his death the German commander in Berlin surrendered.
Germany tried to hold out for another week but the Allies forced her to surrender.
