World War II (1939-1945), the Battle of Normandy, which lasted
from June 1944 to August 1944, resulted in the Allied liberation
of Western Europe from Nazi Germany’s control. Codenamed Operation
Overlord, the battle began on June 6, 1944, also known as D-Day,
when some 156,000 American, British and Canadian forces landed
on five beaches along a 50-mile stretch of the heavily fortified
coast of France’s Normandy region. The invasion was one of the
largest amphibious military assaults in history and required extensive
planning. Prior to D-Day, the Allies conducted a large-scale deception
campaign designed to mislead the Germans about the intended invasion
target. By late August 1944, all of northern France had been liberated,
and by the following spring the Allies had defeated the Germans.
The Normandy landings have been called the beginning of the end
of war in Europe. (source : History.com).
