After months of planning and build-up, Supreme Commander Dwight Eisenhower set Operation Overlord for June 6, 1944: some 7000 ships in the British Isles set to sea and sailed across the English Channel, and, under the leadership of Field Marshall Bernard Montgomery, 135,000 troops landed and stormed Feldmarschal Erwin Rommel's German positions along 80 km of the Normandy coast.
7000 British ships sailed across the English Channel.
 The text only says "some 7000 ships in the British Isles set to sea and sailed across the English Channel" - not the nationality of all the ships. The model assumed it.
