Next in importance to Mesopotamia came the Indian postal services in Egypt, Palestine and Salonika, and in these places the Indian field post offices worked side by side with the British Army Postal Corps. In 1915 they were under the control of Mr. A. J. Hughes as Deputy Director, who was succeeded later by Mr. S. C. Sinclair. In 1915 Indian field post offices were sent to Gallipoli, and the work done by them there won the warm appreciation of the military authorities. The extension of operations to Palestine necessitated the despatch of a number of field post offices to that country. In 1918 it was found necessary to separate the postal contingent at Salonika from the control of the Deputy Director in Egypt, and the force was placed in charge of Mr. A. Gillespie as an independent Assistant Director, with a staff of 1 base postmaster, 2 inspectors, 28 field postmasters and clerks and 36 menials. The Salonika postal service extended to Baku and Constantinople, where there were Indian field post offices. Field post offices were sent to East Africa in 1914 under the control of Mr. K. A. Appleby, who was subsequently made a Brevet Lieutenant-Colonel. The organization consisted of a base office, 25 field post offices, with a staff of 4 superintendents, 6 inspectors, 1 base postmaster, 25 field postmasters, 76 clerks and 67 menials. About a million letters and parcels were handled monthly by this staff, and work had to be carried on under the most trying conditions, as many of the mail lines traversed country covered with thick jungle. In 1917 and 1918 the whole postal service of German East Africa was carried on by the Indian Field Post Office, and the greatest credit is due to Lieutenant-Colonel Appleby for the excellent arrangements made by him. In 1918 Lieutenant Kilman was sent to take control of the field post offices attached to the East Persian Cordon between Meshed and Dalbandin. The East Persian Cordon was subsequently known as the Force in East Persia, and the postal organization consisted of 1 Base post office and 13 field post offices, with a staff of an Assistant Director of Posts and Telegraphs, 1 inspector, 1 base postmaster, 13 field postmasters, 31 clerks and 54 menials.
