How was the course of World War II influenced by the D-Day invasion? Germany's hold on Europe weakened as Allied forces invaded and established a
foothold in Italy.
German forces were driven back across Europe as the Soviet Union attacked
after a stalled German offensive.
Germany diverted resources from the Eastern Front when it opened a second
front in Europe.
Allied forces failed to establish a position in Europe as a result of the attempted
invasion, lengthening the war.
