The arrangements for conveying the mails between the base office and the field offices devolves on the supervising officers, and endless difficulties have to be faced in order to obtain transport. A great deal depends on the personality of the postal officer in charge. If he is a pleasant fellow and popular with the transport staff he can get most things done, but, if he is insistent on his rights and has not learnt the meaning of "give and take" on a campaign, he will get nothing but excuses and regrets, the mail bags will be left behind in the last camp, irate Colonels will write to their personal friend the Director-General and the promising career of a conscientious public servant will be seriously injured. In Appendix H is given a list of the most important expeditions in which field post offices have been employed, with a brief account of the arrangements made on each occasion. Most of these were small frontier wars and little difficulty was felt in providing the personnel. The Great War, however, was a very different matter. It necessitated the despatch of large numbers of post offices all over the world, and the demand on the resources of the Post Office of India was on such a vast scale that an account of it has been reserved for a separate chapter. CHAPTER XVIII THE INDIAN FIELD POST OFFICE DURING THE GREAT WAR In 1914, when war broke out, a large postal contingent accompanied the troops sent to France. It was under the control of Mr. Pilkington, Assistant Director-General of the Post Office, who had the rank of Lieutenant-Colonel, and it comprised one Base Office and 22 field offices, with a staff of 13 supervising officers, 22 field postmasters, 84 clerks and 78 menials. During the early years of the war the work performed by this staff was very heavy. Frequently over 23,000 letters and 2000 parcels would arrive for the Indian contingent in one day, while newspapers published in England were regularly received for delivery to the troops. At the end of 1916 the Indian field postal staff in France was considerably reduced, as large numbers accompanied the Indian troops transferred to Egypt and Mesopotamia, and at the end of the war only one or two field offices remained to serve some Labour Corps units which had been left behind.
