Assembling two Mulberry Harbours the day after the landings on 7 June 1944 was one of the most remarkable engineering feats in history.

Following this, No. 6 Commando were used in the defence of the beachhead and the subsequent operations to break out from Normandy before being withdrawn with the rest of
