Built 1922 at Baltimore Dry Dock & Shipbuilding Company, Maryland, as FORT MCHENRY. She entered Socony-Vacuum's British-flag
fleet by a long, circuitous route, having borne three previous names (FORT MCHENRY, VACOIL and SCHULAU) under two other flags
before finally  becoming EOCENE.

The original US-flag FORT MCHENRY was equipped with a towing machine and a "wireless" - the latter with a "daylight range" of 250 miles.
She was fitted to carry either cargo or water ballast in her double bottoms.
In April 1924 FORT MCHENRY was purchased by the Vacuum Oil Company and renamed VACOIL, retaining her American registry. Five
years later, in January 1929, ownership of the VACOIL was transferred to a Vacuum affiliate, the Deutsche Vacuum Oil Company AG, and
renamed SCHULAU under German registry. SCHULAU remained with this Vacuum affiliate for four years after the merger, lifting Russian
kerosene and Baku benzine out of Batumi, USSR, for the Mediterranean markets. Not until February 1935, was the SCHULAU transferred
to the British flag under the holding ownership of the Standard Transportation Company Limited of Hong Kong and renamed EOCENE. At
that time she was assigned to the Istanbul fleet.

She was working out of Istanbul when WWIl broke out. Life continued as usual for EOCENE, until April 1941, when she was immobilised
in the Bosphorus due to the presence of strong enemy forces in the Aegean Sea and around the Dodecanese Islands. In August of that
year the Germans got rather involved on the Russian front, and EOCENE, then under British Admiralty control, tried to run the Aegean
Sea blockade. She left Istanbul on 18 August, kept in Turkish territorial waters as much as possible and eventually arrived safely at Port
Said, Egypt. There she was taken over for special service with the British Sea Transport, carrying aviation gasoline to support
General Montgomery's operations in the African desert.
In the course of this duty EOCENE left Alexandria in convoy for Tobruk. On 20 May 1942, 60 miles east of her destination, she was torpe-
doed. Luckily there was no immediate fire, but the benzine fumes were so strong that men were sickened and fear of explosive fire ran
high. Captain Henry W Willcox gave orders to abandon ship. Subsequently all hands were picked up by a convoy rescue ship, and from
its decks they watched EOCENE break in the middle and go down. No lives were lost.
