Robert Lochner (engineer) harbours to Franklin Roosevelt and Winston Churchill. The decision to go ahead was taken and full-scale trials of the floating breakwater started in April 1944. During the trial, an onshore gale produced heavy seas, but Robert's bombardons calmed the waves effectively. Assembling two Mulberry Harbours the day after the landings on 7 June 1944 was one of the most remarkable engineering feats in history. A total of 1,500,000 tons of harbour equipment had to be taken across the channel in an operation involving 150 Allied tugs, and by D-Day 'plus 12', most of Lochner's concrete breakwaters were in position.

British logistics in the Normandy Campaign the purpose. During the first seven weeks after the British and Canadian landings in Normandy on D-Day, 6 June 1944, the advance was much slower than anticipated, and the lodgement area much smaller. The short lines of communication provided an opportunity to build up reserves of supplies. Two army roadheads were created, No. 1 Army Roadhead for I Corps and No. 2 Army Roadhead for XXX Corps. When the Canadian First Army assumed control of the British I Corps on 21 June, No. 1 Army Roadhead also passed to its control. No. 2 Army Roadhead formed the nucleus of what
