ex HAMMAC - 1926
Commissioned July 1921, at Bethlehem Shipbuilding Corporation, Alameda, California, where she had been built for original
owners as HAMMAC. Purchased by General Petroleum Company in 1923 and acquired by Socony in 1926.

EMIDIO was left on the Pacific coast to serve the local needs of General Petroleum Company. She had the unhappy distinction
of being the first US tanker definitely known to be torpedoed and lost in WWII. The only prior US tanker loss was the ASTRAL,
whose complete disappearance with all hands in November 1941 has never been solved.
On 20 December 1941, 13 days after Pearl Harbor, EMIDIO was torpedoed and shelled by an enemy submarine, presumably Japanese,
on the surface and in daylight, about 20 miles off the coast of California. Five men lost their lives. The ship was abandoned.

Despite later attempts to salvage her, EMIDIO drifted ashore on the rocks off Crescent City, California. She was given up as lost on
26 December, and the hulk was sold in January 1942, "as is, where is" to R C Porter of San Francisco, who paid $1000 for
salvage rights.
