Nice quiz, but Cherbourg was encircled on 21 June 1944 and surrendered on 26 June 1944, not on D-Day itself. Cherbourg was not even an initial D-Day objective, Caen was but was not captured for several weeks after D-Day.
The fact that Cherbourg was not captured emphasised the importance of the Mulberry harbours, which were largely destroyed by a storm some time after D-Day.
