[2] She had a single screw, driven by a three-cylinder triple-expansion steam engine built by Richardsons Westgarth & Company of Hartlepool, England.

[5] When the First World War started at the end of July, all of Isthmian's ships were transferred to the direct ownership of the US parent company, and re-registered in New York.

[7] USS St. Francis made three voyages for the Naval Overseas Transportation Service: two to France before the Armistice of 11 November 1918 and one to Latin America afterwards.

For her first voyage she loaded US Army supplies at Baltimore, sailed to New York, and there joined a convoy which left on 4 July.

The convoy reached Brest, France on 19 July, from where St. Francis continued to England to discharge her cargo.

She returned through the canal, loaded a commercial cargo of sugar at Cienfuegos, Cuba, and on 8 April arrived in New York.

The Navy decommissioned her at New York on 28 April 1919, and returned her via the US Shipping Board to her owners,[7] who restored her name to San Francisco.

In 1933 the International Freighting Corporation, Inc. bought San Francisco, renamed her Lammot du Pont and registered her in Wilmington, Delaware.

[9] On the evening of 23 April 1942 she was steaming unescorted at 9+1⁄2 knots (17.6 km/h) about 500 nautical miles (930 km) southeast of Bermuda.

Heavy seas prevented the other survivors from reaching it, and the two men aboard the broken raft were lost.
