D-Day Gold Beach - Arrowmanches - Remnants of Mulberry Harbour

Mulberry Harbour was the marvellous invention which consisted of pre-cast concrete sections which were towed across the English Channel to Normandy, then bolted together to create artifical harbours to allow allied ships to offload vehicles, artillery, and supplies at speed to reionforce and supply the Allied bridgehead established on D-Day, 6th June 1944. 

The Allies took around 10,250 casualties on D-Day (including the Britsh 6th Airborne Division's casualties on Op TONGA), of whom around 4,400 were killed in action; one of the aspects we remember on the anniversary of D-Day, the scale of sacrifice made to liberate Europe.
