Up to 1884 there was no real cause for complaint; it had been found necessary in this year to blockade the Chagarzais, Akazais and Pariari Saiyids, and the same punishment was extended later to the Hassanzais; but it was not until June 1888 that a serious outrage occurring on the Agror frontier necessitated the despatch of another expedition to the Black Mountain. On the 18th of this month an attack was made upon a small party of British troops within British territory by Akazais, Hassanzais and Pariari Saiyids, and two British officers and four men were killed. Immediately upon this, large bodies of these tribesmen assembled with the intention of attacking Agror, but dispersed again without taking any further offensive action; the Indian Government now once more took into consideration the question of punitive measures against the Black Mountain tribes, and on the 29th August an expedition was decided upon. [Sidenote: Expedition of 1888] _Expedition against the Black Mountain Tribes, 1888._—The force was formed on the 7th September, 1888, and consisted of three mountain batteries, one company sappers and miners, four battalions of British, nine of Native infantry, with two battalions of Kashmir infantry and the Khyber Rifles, and was placed under command of Brigadier-General (temporary Major-General) J. McQueen, C.B., A.D.C. The total strength was 9416 of all ranks, and the force was organised in two brigades under Brigadier-Generals Channer and Galbraith, each brigade being sub-divided into two columns. There was further a reserve composed of a regiment of cavalry and two battalions of infantry. Headquarters and the first, second and third columns were directed to concentrate at Oghi in the Agror valley by the 1st October, and the fourth column at Darband on the Indus on the same date; and the object of the expedition was stated to be the coercion into submission of the Akazais and the Khan Khel division of the Hassanzais, with the punishment of any clans or divisions which might assist these tribesmen in their opposition to our troops. The following were the orders issued for the advance of the four columns: No. 1 Column to move on the 4th to Mana-ka-Dana, and the following day to Chitabat, leaving a sufficient force at Mana-ka-Dana to protect its line of communications. No. 2 Column to advance up the Barchar spur on the 4th, occupying Barchar; thence moving on the 5th to the crest of the ridge, one regiment being at once detached to the left to meet No. 3 Column.
