After the invasion of Normandy, Germany launched a counteroffensive. The battle that followed is known as the Battle of the Bulge, or the Battle of the Ardennes. It was the German attempt to break though Allied defenses; in fact, it was named "Battle of the Bulge" because of the wedge-shaped formation that the German forces took. Ultimately, however, it failed, and was the last major German attack on the Western front in World War II.
D-Day is known as one of the most stirring turning points in history, and itself set the stage for victory in Europe less than a year after. It was the largest attack in history that came from the sea, and began the Allied invasion of westen Europe. On August 25, France was liberated.
The Doolittle Raid was an air attack on Japan led by Lieutenant Colonel James H. Doolittle. It was originally meant to be a diversion, and meant to boost Allied morale. Tokyo and Nagoya were attacked, although the damage was not major. In response, the Japanese command executed three captured American airmen and resolved to eliminate any further risk of air raids.
