Washington was launched in May 1933 by the New York Shipbuilding Company of Camden, New Jersey, and operated as a passenger liner from New York City to Plymouth, England, and Hamburg, Germany. Renamed Mount Vernon 6 June 1941, the liner was acquired by the Navy 16 June 1941 and commissioned at the Philadelphia Navy Yard the same day, Captain Donald B. Beary in command.

Converted for naval use by Philadelphia Navy Yard, Mount Vernon trained along the east coast while mounting tension in the Far East drew the United States toward participation in World War II.

The Preamble to Convoy WS-12X (the USA has not declared war on Japan or Germany yet) edit

The Atlantic Conference was held on 9 August 1941 in Placentia Bay, Newfoundland, between Prime Minister Winston Churchill and President Roosevelt. Besides the "official" agenda, Churchill hoped to obtain considerable assistance from the USA, but the American President had his political hands tied. On 1 September 1941, Roosevelt received an urgent and most secret message asking for US Navy troopships manned by Navy crews and escorted by U.S.N. fighting ships to carry British troops for the purpose of reinforcing the Middle East. On 4 September the US destroyer, USS Greer (DD-145), came under an unsuccessful U-boat attack. Roosevelt gave authority to the US Navy to "shoot to kill". On 5 September the President assured the British leader that six vessels would be provided to carry twenty thousand troops and would be escorted by the American Navy.

The chief of Naval Operations ordered troop ships divisions seventeen and nineteen, on 26 September 1941, to prepare their vessels for approximately six months at sea. These transports were to load to capacity with food, ammunition medical supplies, fuel and water and were to arrive at Halifax, NS on or about 6 November and after the arrival of a British convoy from the UK were to load twenty thousand troops. The Prime Minister mentioned in his letter that it would be for the President to say what would be required in replacement if any of these ships were to be sunk by enemy action. Agreements were worked out for the troops to be carried as supernumeraries and rations to be paid out of Lend Lease Funds and officer laundry bills were to be paid in cash. All replenishments of provisions, general stores, fuel and water would be provided by the UK. Fuel and water would be charged for the escorts to the UK in Trinidad and Cape Town only. The troops would conform to US Navy and ships regulation. Intoxicating liquors were prohibited. It was further agreed that the troops were to rig and man their own anti-aircraft guns to augment the ships batteries.[1]

So, convoy WS-12X is most extraordinary. 30 days BEFORE the Japanese attack on Pearl Harbor on 7 December 1941 and the German declaration of war on the USA on 11 December 1941; we have six American transports and American escort carrying British soldiers.

Mount Vernon was the lead ship in Operation Stepsister, the movement of Australian troops from North Africa and the Middle East to Southeast Asia, the Dutch East Indies and Australia in response to war in the Pacific, and was carrying 4,668 of those troops in waters south of the Dutch East Indies even as allied naval forces were withdrawing in the face of Japanese attacks.[15][16] On 9 March Mount Vernon delivered the returning Australian Imperial Force (A.I.F.) troops to Adelaide.[17]
