Political map of South & Southwest Asia 29 January 1915 (Ottoman Raids in Persia and Sinai): The defeat at Sarikamish (Battle of Sarikamish) did not end smaller scale Ottoman offensives, with one Turkish unit even managing to briefly capture the poorly defended Persian city of Tabriz from the Russians. Further south the Ottomans expanded the war in Persia (Persian Campaign) by allying with local tribesmen to threaten the British-held oilfields, while in Egypt they crossed the Sinai to contest British control of the Suez Canal (Raid on the Suez Canal).
