Established in December 1917,
Dunsterforce was an Allied military force named after its commander, General
Lionel Dunsterville, of fewer than New Zealand, British and Canadian officers and NCOs, drawn from the
Western and
Mesopotamian fronts. The force was intended to organise local units in northern Iran and southern Caucasus, to replace the Tsarist armies that had fought the Ottoman armies in Armenia and occupied northern Iran in co-operation with the British occupation of the south, to create a cordon, preventing German and Ottoman agents from reaching central Asia, Afghanistan and India.
