Garland transferred to the General List of officers on 6 May 1920 with the grade of a class FF staff officer (equivalent to staff captain), but without pay or allowances. He relinquished his commission on 14 May that year, but received permission to retain his rank. He was later appointed major and became director of the Arab Bureau in Cairo, under the High Commissioner to Egypt Lord Allenby. Garland's main task was to resolve the post-war state of the Arabian Peninsula which the war had left in the hands of a number of competing Arab tribes and to tackle the delicate matter of the ending of lavish subsidies from the British treasury to Hussein bin Ali, Sharif of Mecca.
