USAT Warren was the former Hamburg America Line liner Scandia, laid down as the Scandiinavia at AG Vulcan Stettin, launched on 24th Aug 1889.

[4][5] Warren underwent major overhaul and was "practically reconstructed" during fiscal year 1916 (1 July 1915—30 June 1916) including boiler replacement.

[15] In the summer of 1902 the ship transported Dr. Sheldon Jackson from Seattle to Nome in connection with his work with introducing reindeer into Alaska.

[16] Forty-three Filipino political prisoners had been deported to Guam by General Arthur MacArthur Jr. for their loyalty to the Philippine Revolution during the Philippine–American War.

Those were done by piling coal and pig iron on the forward decks and removing heavy material from aft so that the stern was raised out of the water enough for the repairs.

[18][note 2] During August 1914 the Insular Government of the Philippine Islands dealt with stabilizing the market for staple goods in a crisis related to shipping at the start of war with Germany.

[4][21] In May 1924 Warren[note 3] sank for unknown reasons on the Huangpu River in the harbor of Shanghai, next to the pier, and was finally scrapped in 1929.
