The oil fields of Binagardy, Baku, August 1918

Photograph, World War One, Caucasus (1914-1918), 1918.

Both the Baku oil installations and the strategically important Trans-Caucasian railway were deemed vital to the Allied war effort so after the Russian armies in the Caucasus collapsed following the October Revolution (1917), the British attempted to bolster the Allied position there by despatching a military mission called Dunsteforce.

The resources available to Dunsterforce, both in terms of men and equipment, were insufficient to accomplish this and Baku fell to the Turks on 14 September 1918.
