The object of the expedition, which was under the command of Brigadier-General Sir William Lockhart, K.C.B., was to overawe the recalcitrant Samil clans of the Urakzai tribe in the Miranzai Valley. The force was ordered to the front in January, 1891, and advanced in three columns, the first column having its base at Shahu Khel, the second at Tog and the third at Hangu. Mr. A. Bean, Superintendent of post offices, Peshawar Division, was placed in charge of field postal arrangements connected with the force in addition to his own duties. _The Wuntho Expedition._ On the 15th February, 1891, the station of Kawlin was suddenly attacked by a party of rebels from the Wuntho State, in Upper Burma, and a few police who formed the garrison of the place had to evacuate it. The post office had to be abandoned and the sub-postmaster had to come away along with the other officials. A combined force of police and military, consisting of about 2500 men, was at once organized and advanced on Wuntho from Shwebo, Katha and Tigyaing to put down the rebellion and bring the country under permanent occupation. The troops employed were not designated a Field Force, and the postal arrangements were therefore carried out on ordinary scale and not according to the rules of the Field Service Manual. _The Isazai Field Force._ In September, 1892, the Government of India decided to send out an expedition under Major-General Sir William Lockhart to punish certain villages of the trans-Indus Isazai clans who had harboured Hashim Ali Khan of Seri in contravention of their agreement entered into at Seri in May, 1891. A force of about 4000 men of all arms concentrated at Derband and was styled the "Isazai Field Force." On the 17th September, 1892, Mr. C. J. Dease, Superintendent of post offices, was deputed to make the special arrangements for the force with the assistance of an inspector. _Kurram Field Force._ In the beginning of October, 1892, the Government of India decided to depute a Political officer at the head of a force in the Lower Kurram Valley. The object was to expel the Chikkai tribes from the valley and to effect a thorough settlement of the country. The force which accompanied the Political officer, Mr. W. R. H. Merk, C.S.I., consisted of about 2500 men, including followers. Mr. P. Sheridan, Postmaster-General, Punjab, arranged for field post offices, and the Superintendent of post offices, Peshawar Division, was placed in charge. By the end of October the presence of troops in Kurram was no longer necessary, and the field offices were closed with the exception of the head-quarters office, which was retained for the use of the garrison. _The Wano Expedition._
