The object of the expedition was to explore the borders of the Zhob Valley and to take steps either to capture the outlaw Dost Muhammad or to expel him from the Kakar country and to coerce the Khiddarzai Shirani tribe into submission. Towards the middle of September, 1890, intimation was received from the Quartermaster-General in India that a force of about 2000 men, besides camp followers, was about to start for the Zhob Valley, and on the 27th of that month a small field post office, consisting of a sub-postmaster and two peons, started from Quetta with a portion of the troops for Hindubagh, which was to be the general rendezvous. The expedition was commanded by Sir George White. _The Black Mountain Expedition._ In 1891 a force was sent for operations against the Hassanzai and Akazai tribes of the Black Mountains. The strength of the force, which was under the command of Major-General Elles, C.B., was about 6800 men, and it advanced from Darband in two columns--one marching via Baradar and Pailam to Tilli, and the other along the river route via Kotkai and Kunhar. The postal arrangements were made by Mr. W. T. van Someren under the direction of Mr. G. J. Hynes, Postmaster-General, Punjab. _The Chin Hills Expedition._ The Government of India sanctioned military operations in the north and east frontier of the Bhamo district and Chin Hills during the cold season of 1891-92. In the Bhamo direction the object of the expedition was to explore the amber and jade mines, the Hukong Valley and the country on the east and north-east frontier above the Taeping river on the Chinese border. The expedition had a quasi-military character, and about 5000 troops, including police battalions, operated in various columns, under the direction of Major-General R. C. Stewart, commanding the Burma districts. Mr. F. McCrea, Inspector of post offices, Eastern Division, was deputed to organize and supervise the arrangements. _The Manipur Expedition._ The outbreak in Manipur in 1891, and the consequent massacre of Mr. Quinton, the Chief Commissioner of Assam, and his party, necessitated the despatch of troops to quell the rebellion. The force was designated the "Manipur Field Force," and about 2500 men, including followers, operated from the Tammu side and about the same number from Kohima and Silchar. Mr. W. Roussac was in charge of the postal arrangements with the Tammu column, and Mr. F. P. Williams, assisted by an inspector, with the Kohima column. All correspondence for the Tammu column was sent from India to Rangoon and thence by boats to Kindat. From Kindat to Tammu the mails were conveyed by runners, and a runners' line was opened from Tammu to Manipur. These arrangements worked for a very short time on account of the rapid advance of troops and their immediate return. _The Miranzai Expedition._
