1. There is More to the Allied Normandy Campaign than D-Day
D-Day did not end the war, but it sure was the turning point in the history of World War II. With that significance, D-Day often tends to overshadow the overall importance of the whole Normandy campaign.
It was necessary for the Allied groups to establish a bridgehead, though this was just their first step. They launched a series of additional assaults in the three months that followed D-Day to try and advance further into France. Strong German forces were resisting them all the way. The Normandy landscape was peculiarly characterized by recessed lanes and thick high hedges. These gave the advantage to the Germans and made it difficult for the invaders to penetrate.
Nonetheless, the protracted and bloody Normandy war paved the way for the Allied victory and the eventual liberation the broader Northwest Europe.
