Requisitioned for service as a troopship with the US Navy during World War II, she was renamed USS Joseph T. Dickman (APA-13) and served in the Atlantic and Pacific theaters, being scrapped postwar in 1948.

In January 1926, President Roosevelt was involved in the rescue of the crew of the British cargo ship SS Antinoe that foundered in the Atlantic Ocean.

After the Battle of France began, the State Department sent the President Roosevelt to Galway, Ireland in late May 1940 to pick up Americans who wanted to come home from the British Isles.

[4] Taken over by the War Department in October 1940, it was renamed Joseph T. Dickman and converted to a troopship by Atlantic Basin Iron Works of Brooklyn.

The Atlantic Conference was held on 9 August 1941 in Placentia Bay, Newfoundland, between Prime Minister Winston Churchill and President Roosevelt.

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.

Stores were loaded at Norfolk, Virginia in October and in early November, the troopship proceeded to Halifax, Nova Scotia, to take on board British troops.

[6] Wakekfield (AP-21), with 6,000 men embarked, and five other transports Mount Vernon (AP-22), West Point (AP-23), Orizaba (AP-24), Leonard Wood (AP-25) and Joseph T. Dickman (AP-26) got underway as Convoy WS12-X on 10 November 1941.

Joseph T. Dickman carried further reinforcements to Caribbean bases in June, and spent July on amphibious exercises in Chesapeake Bay.

Training and additional conversion to increase her boat capacity continued into October, when the ship prepared for Operation Torch, the invasion of North Africa.

As a part of Rear Admiral Hall's Gela landing force, she arrived off the beaches 10 July and began the long process of debarkation.

The next major amphibious operation in the campaign to regain Italy was slated for Salerno; and, after training, Joseph T. Dickman arrived off the beaches with Hall's Southern Attack Force 9 September.

Rockets from an LCS attached to the ship helped clear the way for the first wave of boats, and, after receiving near misses from shore batteries, the transport debarked her troops and returned to Mers el Kebir.

On the afternoon of D-Day, she steamed to Portland with casualties, later making a shuttle voyage to the beaches 14 June as troops moved inland to liberate France.

Upon arriving Mers el Kebir 10 July 1944, Joseph T. Dickman began preparations for still another landing, this time in southern France.

After exacting training operations, she sailed from Sicily 13 August 1944, arriving off the Delta Force beaches next day to debark her troops.

In the weeks that followed, Joseph T. Dickman made five follow-up voyages to southern France from Mediterranean staging points as the Allies pressed northward.

Joseph T. Dickman then sailed for the Philippines 24 August; and, upon arrival in Manila 17 September, took on American and Allied soldiers who had been prisoners of the Japanese for transportation to the United States.

Coincidentally, four British enlisted men came on board, who after 3½ years in a prison camp were returning to the United States on the same ship which had carried them from Halifax to Bombay in 1941.
