Admiral Sir William George Tennant KCB CBE MVO DL (2 January 1890 – 26 July 1963) was a British naval officer.

He remained in this capacity when the Repulse was sunk by the Japanese along with HMS Prince of Wales in the South China Sea on 10 December 1941, three days after the attack on Pearl Harbor.

[10] Tennant's party was dispatched on board the destroyer Wolfhound to aid in the evacuation of more than 300,000 British and French troops left stranded when France fell to the Nazis.

Tennant stayed right up until the last ships left on 2 June, patrolling the beaches of Dunkirk with a megaphone searching for British troops.

[12] Tennant and Repulse joined Admiral Sir Tom Phillips' Force Z, sent to Singapore to counter Japanese advancement in the Pacific, in December 1941.

Nonetheless, Repulse eventually succumbed to a pincer attack and was hit by five torpedoes, sinking within twenty minutes, with great loss of life.

[15][16] In June 1944, Tennant was placed in charge of the naval side of the transport, assembly and setup of the two Mulberry harbours that provided port facilities for the coming invasion of Normandy.

For his efforts in the success of the Normandy invasion, Tennant was appointed Commander of the Order of the British Empire by King George VI and was awarded the United States Legion of Merit.
