# SS Antilles (1906)

SS Antilles was a US passenger-cargo ship launched in 1906. Chartered by the US Army in 1917 for use as a troop transport, Antilles was sunk by a German U-boat on October 17, 1917, resulting in the loss of 67 lives. At the time of its sinking the Antilles was the largest single largest loss of US lives to that point in World War I.

## History
### Construction

Antilles, US official number 204018, was a 6,879 GRT ship built in the shipyards of William Cramp & Sons Shipbuilding Company, Philadelphia, Pennsylvania delivered April 1907. Antilles was a twin screw steam vessel with nominal speed of 15 knots (28 km/h; 17 mph) and dimensions of 421 feet 11.5 inches (128.6 m) on load line, extreme beam 53.2 feet (16.2 m) and mean draft of 26 feet (7.9 m) with a displacement at normal coal supply of 10,500 tons.
The vessel was operated as a combined passenger and cargo ship by the Southern Pacific Steamship Company from the time of its launch until 1917. Antilles and sister ship Momus, along with several other ships, operated between New York and New Orleans with Southern Pacific Steamship's Morgan Line.

### Destruction

Following American entry into World War I, selected by the Shipping Control Committee, Antilles was turned over May 26, 1917, and chartered by the United States Army for use as a civilian crewed US Army Chartered Transport (USACT). The ship was among those in the first troop convoy to depart on June 14, after considerable confusion and delays in troop loading, from the Hoboken Port of Embarkation. Antilles sailed from New York on September 24 in a four ship convoy, designated Group Number 8, composed of Antilles, a new Navy transport Henderson, another Army chartered transport Finland and another Army chartered ship that turned back, Lenape. The convoy made the crossing successfully but both Antilles and Finland were torpedoed on the return voyage.
On October 17, 1917, three days out of Saint Nazaire, France and two days out of Quiberon Bay where another ship had joined the convoy for the return voyage, Antilles was torpedoed by German U-boat U-62 reportedly sinking in four and a half minutes after being hit. The ship was in a small convoy composed of Antilles, Henderson and Willehad escorted by the patrol yachts USS Alcedo, USS Aphrodite, USS Corsair and USS Kanawha. Both Aphrodite and Corsair had been among the escort on that first convoy to France in June. In rough weather Kanawha had been forced to turn back due to the weather with the convoy slowed by the same weather. At about 6:45 a.m., during a course change, Antilles was astern of Corsair and seen to suddenly sheer out of formation and began settling by the stern. Alcedo turned back to where Antilles had sunk and began picking up survivors while Corsair circled in a search for the submarine until about 8:30 with no sign of a submarine found and the search for survivors and the submarine discontinued at 10:30.
The majority, 118 survivors, were rescued by Alcedo with 50 rescued by Corsair. Among the fifty persons rescued by Corsair was then Brigadier General William Sharp McNair who had been ordered to return to take command of 151st Field Artillery Brigade. A total of 67 people died in the sinking. The loss of life was the first case in the war involving a large number of US casualties.
Survivors were landed in France on October 21 where they were immediately cared for by the Red Cross. Those that died were some of the first to come under the new war-insurance law allowing payment of $6,000 ($ 142,700 in 2025) payable to families in installments of $25 ($590 in 2025) per month over twenty years.
