Video: Dieppe Raid (at 1:58)

(Wednesday, August 19, 1942, 5 a.m. local time, part of the North West Europe Campaign of World War II) — An Allied force of 7,000 men today carried out a large daytime raid against German positions at the French seaport of Dieppe, suffering more than 50 percent casualties.

While it ended in disaster for the Allies, the Dieppe Raid provided valuable logistical information later used in planning the successful 1944 Allied landing at Normandy.
