A Panamanian subsidiary of Esso bought her at the end of 1936 and she was sunk by the German submarine U-68 in the Caribbean on June 4, 1942 about 41 nautical miles (76 km) southwest of Isla de Mona, Puerto Rico.

[4] She was named after James Stillman, who was chairman of National City Bank and invested with partners including William Rockefeller of Standard Oil.

She underwent repairs at Rotterdam and then on 24 March 1937 her new owner transferred her registration from Britain to the Panamanian flag of convenience.

[2] She sailed to Halifax, Nova Scotia, joined an eastbound transatlantic convoy and reached Le Havre on 22 December.

Stillman was blacked out in accordance with wartime orders and at dusk the two ships lost visual contact.

Stillman received coded messages warning her that enemy submarines were in the area, so at 2000 hrs she altered course to 95 degrees.

Stillman was about 41 nautical miles (76 km) southwest of Isla de Mona[5] between Puerto Rico and the Dominican Republic when U-68[7] hit her with a torpedo on the ship's starboard side abaft her midships accommodation block.

[5] The three workaways and a US Navy coxswain were trapped in the midships accommodation block but managed to escape by using an axe to break a louvre covering a porthole.

[5] At about 2135 hrs First Officer Harry Bansen and Captain Larsen were trying to launch the work-boat when U-68[7] hit the ship with a second torpedo, again on the starboard side but further aft.

Stillman settled by the stern, her bow rose vertically and she sank within two or three minutes of the second torpedo hitting her.

[8] Three men had been lost: Second assistant engineer Laurence Finn, pumpman George Wickline and able seaman John Lane.

3, whose most senior occupant was the Chief engineer, Fred Lewis, landed at Boca de Yuma,[8] which is almost at the easternmost tip of Hispaniola.

4, whose most senior occupant was the First assistant engineer, Laurence Moore,[8] landed at La Romana,[9] which is on the south coast slightly further west.

[8] A United States Army aircraft sighted the three linked rafts at about 1100 hrs and returned in the late afternoon to guide United States Coast Guard 83-foot patrol boat 83310 (formerly CG 460) from San Juan, Puerto Rico, which reached the rafts just before dusk.

[9] The 25 who were civilian crew were repatriated on a Pan American World Airways flight from Ciudad Trujillo to Miami.

[9] The 25 survivors rescued by the US Coast Guard sailed home from Puerto Rico on the Clyde-Mallory Lines passenger ship[7] SS Seminole, which landed them at Tampa, Florida on 26 June.
