D-Day (game)

D-Day is a board wargame published by Avalon Hill in 1961 that simulates the six months of the European Campaign of World War II from the Normandy Invasion to the crossing of the Rhine. It was the first wargame to feature the now ubiquitous hex grid map and cardboard counters, and was revised and re-released in 1962, 1965, 1971, 1977 and 1991.
