Naval operations for the invasion were described by historian Correlli Barnett as a "never surpassed masterpiece of planning".
In overall command was British Admiral Sir Bertram Ramsay, who had served as Flag officer at Dover during the Dunkirk evacuation four years earlier.
He had also been responsible for the naval planning of the invasion of North Africa in 1942, and one of the two fleets carrying troops for the invasion of Sicily the following year.

The invasion fleet, which was drawn from eight different navies, comprised 6,939 vessels: 1,213 warships, 4,126 landing craft of various types, 736 ancillary craft, and 864 merchant vessels.
The majority of the fleet was supplied by the UK, which provided 892 warships and 3,261 landing craft.
In total there were 195,700 naval personnel involved; of these 112,824 were from the Royal Navy with another 25,000 from the Merchant Navy, 52,889 were American, and 4,998 sailors from other allied countries.
The invasion fleet was split into the Western Naval Task Force (under Admiral Alan G Kirk) supporting the US sectors and the Eastern Naval Task Force (under Admiral Sir Philip Vian) in the British and Canadian sectors.
Available to the fleet were five battleships, 20 cruisers, 65 destroyers, and two monitors.
German ships in the area on D-Day included three torpedo boats, 29 fast attack craft, 36 R boats, and 36 minesweepers and patrol boats.
The Germans also had several U-boats available, and all the approaches had been heavily mined.
