Protecting supply traffic after D-Day

How did coastal convoys cope with supplying Europe after D-Day?

The task was difficult, but more escorts were assigned and the Channel approaches were heavily barred while German attention shifted toward cross-Channel traffic.

Moving the invasion force ashore did not end the maritime logistics problem. Escort resources increased for the cross-Channel supply lanes, while barriers at the Channel's ends helped restrict German interference. Protecting the flow of follow-on supplies was a continuing naval operation.
