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.

Australian contribution to the Battle of Normandy (EATS), were stationed in the United Kingdom (UK) and took part in operations against Germany. The Australian Government had very little influence over where Australian graduates of EATS were posted, and many were assigned directly to British units. As of 6 June 1944, 1,816 Australian airmen (including 584 pilots) were posted to RAF squadrons. Many of the thousands of Australian ground crew in the UK at this time were also serving with RAF units. In addition, ten RAAF flying squadrons were stationed in the UK. These included one regular RAAF unit, No. 10 Squadron, and nine temporary "Article XV squadrons,"
