Field Post Office No. 25 was the office at Camp Khar on the Swat Frontier, Nos. 5A and 22 were respectively at Zam and Jani Khel in connection with the blockading of the Mahsud Waziris (_Type of Fig._ 70). [Illustration: 70] Indian stamps were also used by the forces engaged in the Somaliland campaign of 1903-4, at first without overprint, of which the following are types of the postmarks (_Figs._ 71, 72): [Illustration: 71 72 73 74] and during 1903 stamps of India appeared overprinted for use in British Somaliland (_Fig._ 73). Colonel Younghusband's mission to the Tibetan Government was accompanied by army postal service which set up its base in the Chumbi valley, and during the occupation of the forbidden city a field post office was set up at Lhassa. Indian stamps used on this mission are recognisable by the postmarks of Lhassa, including two mis-spellings of the name LAHASSA (_Fig._ 74), and LAHSSA (_Fig._ 75). [Illustration: 75 76 77 78 79 80 81 82 83 84 85 85A] The Indian forces in South Africa also had their own postal establishment, with a special series of postmarks. In the present campaign the Indian forces are accompanied by fully-equipped field postal arrangements, and following up the precedent of the China Expeditionary Force, the Indian Expeditionary Force in Europe is furnished with a set of current Indian postage stamps, cards, etc., overprinted I.E.F. (_Figs._ 76-85). The Indian troops enjoy free postage on unregistered letters and postcards posted to the United Kingdom, France, and India, but correspondence to all other countries, such as Switzerland, Holland, Scandinavia, and the rest of the world has to be prepaid with I.E.F. stamps, as also the parcels and registered letters for all countries.
