History of Sussex airfields around Sussex. During the lead-up to the D-Day landings, the people of Sussex were witness to the build-up of military personnel and materials, including the assembly of landing crafts and construction of Mulberry harbours off the county's coast. Five new airfields were built to provide additional support for the D-Day landings, four near Chichester and one near Billingshurst. A legacy of the D-Day landings are the sections of Mulberry harbour that lay broken and abandoned on the sea floor off the coast, of Selsey Bill, having missed the invasion. Sussex was an industrial county, from the stone age, with
D-Day (game) part due to its simplicity. Along with "Stalingrad" and "Afrika Korps", it was considered one of the "classic" games released in the 1960s by Avalon Hill, all of which shared a similar move-attack-advance game system. D-Day (game) D-Day is a board wargame published by Avalon Hill first in 1961 and later re-released in 1965, 1971, 1977 and 1991. An operational/strategic simulation of the Western Front between June and September, 1944, the game simulates the invasion by the Allies of France while it was occupied by the Axis Powers. The title references the Normandy Landings in France on 6 June 1944,
