The North Persia Force (Norper force) was a British military force that operated in Northern Persia from 1918 to 1920. Following the British abandonment of Baku on the night of 14 September 1918, Major General Lionel Dunsterville evacuated the forces under his command, known as the Dunsterforce, in the dead of night, arriving in Bandar-e Anzali the following day. Two days later he was relieved of command, that position being taken by Major General W. M. Thomson.{{cite book |last1=Minez |first1=Roland P.
