Victory was never certain, as the Allies had engaged in deadly air-to-air combat against Luftwaffe, and ground forces fought their way through Nazi Panzer divisions and armored columns of divisions. Fighting had been particularly intense after the June 6, 1944 of D-Day Invasion, the Allied invasion of Normandy in Operation Overlord, with many lives lost.
By the beginning of April, 1945, the Allied forces had begun to see signs that the war was in its final days. It was also at this point that the Allies finally became aware of the magnitude of the atrocities perpetrated by the Nazis at concentration camps such as Ohrdruf, discovered by American troops on April 4th.
