World War II service
Aquitania, with a normal troop capacity of 7,400, was among the select group of large, fast former passenger ships capable of sailing independently without escort transporting large numbers of troops that were assigned worldwide as needed. These ships, often termed "Monsters" until London requested the term be dropped, were Aquitania, Queen Mary, Queen Elizabeth, Mauretania (II), SS Île de France and SS Nieuw Amsterdam (1937) with "lesser monsters" being other large ex-liners capable of independent sailing with large troop capacity that accounted for much of the troop capacity and deployment, particularly in the early days of the war.
Plans to replace Aquitania with the newer Queen Elizabeth in 1940 had been forestalled by outbreak of World War II in 1939.[5] On 16 September 1939 Aquitania, awaiting initial refit as a troop ship, was at pier 90 in New York along with Queen Mary while nearby, at pier 88, were the French ships Île de France and SS Normandie.[1][5] She returned to Southampton and was requisitioned on 18 November.[52]
Aquitania's initial troop transport operation was taking Canadian troops to Scotland, Convoy TC1 in company with Empress of Britain, Empress of Australia, SS Duchess of Bedford, Monarch of Bermuda, HMS Hood, HMS Warspite, HMS Barham, HMS Resolution, HMS Repulse, HMS Furious, December 1939.[1] Meanwhile, a massive transport of Australian and New Zealand troops to Suez and North Africa, with possible diversion to the United Kingdom if events required, was in planning with the numbered convoys to be designated as "US" with the large Atlantic liners assigned a role. The fast convoy designated as US.3 was composed of Aquitania and the liners Queen Mary, Mauretania, Empress of Britain, RMS Empress of Canada (1920), RMS Empress of Japan (1929), and RMS Andes (1939). Aquitania, Empress of Britain, and Empress of Japan, after embarking New Zealand troops at Wellington in May, sailed escorted by HMAS Canberra (D33), HMAS Australia (D84), and HMNZS Leander to join the Australian component off Sydney on 5 May 1940. Joined off Sydney by Queen Mary and Mauretania the convoy sailed the same day to be joined the next by Empress of Canada from Melbourne for a stop at Fremantle 10–12 May before the voyage intended to be for Colombo. About midway to Colombo, on 15 May, the convoy was rerouted due to the rapid German penetrations into France with the ultimate destination of Gourock, Scotland via Cape Town
Now repainted battleship grey, in November 1941 Aquitania was in the British colony of Singapore, from which she sailed to take part indirectly in the loss of the Australian cruiser HMAS Sydney (1934). Sydney had engaged in battle with the German auxiliary cruiser GERMAN AUXILIARY CRUISER Kormoran. There has been much unsubstantiated speculation that Kormoran was expecting Aquitania, after spies in Singapore had notified Kormoran's crew of the liner's sailing and planned to ambush her in the Indian Ocean west of Perth but instead encountered Sydney on 19 November. Both ships were lost after a fierce battle. On the morning of 24 November Aquitania en route to Sydney from Singapore spotted and picked up twenty-six survivors of the German ship but maintained radio silence and did not pass word until in visual range of Wilson's Promontory on 27 November. The captain had gone against orders not to stop for survivors of sinkings.[1] There were no survivors from Sydney.
December saw the outbreak of war in the Pacific, then Japanese advances throughout Southeast Asia and toward Australia, necessitating the redeployment of defensive forces. On 28 December Aquitania and two smaller transports departed Sydney with 4,150 Australian troops and 10,000 tons of equipment for Port Moresby, New Guinea. (On the same date, USS Houston (CA-30) and other U.S. ships evacuating from the north reached Darwin, with USS Pensacola (CA-24), and elements of her diverted Philippine convoy some 260 nmi ahead.) Aquitania was back in Sydney on 8 January 1942. The next effort was reinforcement of Singapore and the Netherlands East Indies with Aquitania transporting Australian troops (whose equipment was in Convoy MS.1) as the single ship MS.2 convoy, under escort of HMAS Canberra. The ship had been the only suitable transport for such a large movement. Originally, transport directly to Singapore was considered, but the danger from aircraft to such a valuable asset and so many troops caused a change of plans. Instead, Aquitania departed Sydney on 10 January, reaching Ratai Bay at the Sunda Strait on 20 January, where 3,456 personnel (including some Navy, Air Force and civilians) were transhipped under a covering naval force to seven smaller vessels (six of them Dutch KPM ships) that would continue to Singapore as convoy MS.2A. Aquitania was returned to Sydney on 31 January.
With the United States in the war, Aquitania (then with a troop capacity of 4,500) had been scheduled for transport duties from the United States to Australia in February, but necessary repairs delayed that. Because her deep draft was hazardous in Australian and intermediate ports in the Pacific Islands, she spent March and April 1942 transporting troops from the west coast of the U.S. to Hawaii. Then Aquitania was temporarily transferred from Pacific duties to support the movement of troops from the United States to Britain, sailing 30 April from New York in a large convoy that transported some 19,000 troops. On 12 May 1942 Aquitania loaded troops at Gourock destined for the war in the Middle East, departing in convoy WS19P on 1 June with destroyers and heavy weather, she broke off independently on 7 June due to her greater speed with designation WS19Q.[53] The first port of call was 48 hours at Freetown (West Africa) on 11 June, then 3 days at Simonstown, South Africa 20 June 48 hours at Diego Suarez, Madagascar from 30 June 24 hours at Steamer Point, Aden on 3 July, and then disembarkation at Port Tewfik, Egypt from 8 July 1942.[54] The return journey was via Diego Suarez, Cape Town, Freetown and then to Boston. By September Aquitania was engaged in a triangular troop deployment of United States-United Kingdom-Indian Ocean voyages. As part of the major redeployment of Australian troops from North Africa to the defence of Australia and start of offensive operations in the Southwest Pacific. Aquitania, Queen Mary, Île de France, Nieuw Amsterdam, and the armed merchant cruiser HMS Queen of Bermuda transported the Australian 9th Division to Sydney in Operation Pamphlet during January and February 1943.
By the buildup for the invasion of Europe in 1944 troop deployments to Britain depended heavily on Aquitania and the other "Monsters" and no allowance could be made for interruption of their service for other transport requirements.
Wartime embarkation at New York is described in some detail in the description of the departure of the Special Navy Advance Group 56 (SNAG 56) that was to become Navy Base Hospital Number 12 at the Royal Victoria Hospital, Netley, England, to receive casualties from Normandy. The unit was sent by "devious routes" by train to Jersey City where under cover of darkness they boarded a ferry crossing to the covered pier 86 in New York where a band played and the Red Cross served their last coffee and doughnuts as they boarded "N.Y. 40", the New York Port of Embarkation code designation for Aquitania, which got underway the morning of 29 January 1944 with some 1,000 Navy and 7,000 Army personnel for arrival at Gourock, Scotland 5 February.
In eight years of military work, Aquitania sailed more than 500,000 miles, and carried nearly 400,000 soldiers,[1][55] to and from places as far afield as New Zealand, Australia, the South Pacific, Greece and the Indian Ocean.[56] Cunard historian Michael Gallagher said: "Wartime Prime Minister Winston Churchill credited Aquitania, with Queen Mary and Queen Elizabeth, for shortening World War II in Europe by a year."[57]
