In the meantime immediate action was necessary to carry out my idea of preventing the different sections of the enemy concentrating at Kabul. I accordingly prepared two columns: one under Macpherson, whose orders were to attack the tribesmen coming from the north before they could join those advancing from the west; the other under Baker, who was instructed to place himself across the line by which the enemy would have to retreat when beaten, as I hoped they would be, by Macpherson.
Macpherson[5] started on the 8th towards Kila Aushar, about three miles from Sherpur, en route to Arghandeh. And on the following morning Baker, with a small force,[6] proceeded to Chihal Dukhteran, giving out that his destination was the Logar valley, and that he would march by Charasia, as I had directed him to make a feint in that direction, and then to turn to the west, and place himself between Arghandeh and Maidan, on the Ghazni road.
To give Baker time to carry out this movement, I halted Macpherson at Kila Aushar on the 9th, whence he sent out two reconnoitring parties—one in the direction of Kohistan, the other, in charge of Lieutenant-Colonel Lockhart,[7] A.Q.M.G., towards Arghandeh.
The intelligence brought in induced me to change my orders to Macpherson. The first party reported that a very considerable force of Kohistanis had collected at Karez-i-Mir, about ten miles north of Kila Aushar, while Lockhart had discovered large numbers of the enemy moving from Arghandeh and Paghman towards Kohistan. Accordingly, I directed Macpherson to attack the Kohistanis, in the hope of being able to disperse them before the people from Ghazni could join them; and, as the part of the country through which he had to move was unsuited to Horse Artillery and Cavalry, I ordered him to leave the mounted portion of his column, except one squadron of Cavalry, at Kila Aushar.
Macpherson made a rapid advance on the morning of the 10th December, skirting the fringe of low hills which intervenes between Kohistan and the Chardeh valley. He reached the Surkh Kotal—which divides western Kohistan from the Arghandeh valley—without opposition. From this point, however, the Kohistanis were sighted, occupying a position about two miles to his right front, their centre on a steep, conical, isolated hill, at the base of which lay the village of Karez-i-Mir.
Macpherson was now able to obtain a good view of the Paghman and Chardeh valleys on his left and left rear, and the numerous standards planted on the different knolls near the villages of Paghman gave ample evidence of the presence of the enemy discovered by Lockhart the previous day, and showed him that, unless he could quickly succeed in scattering the Kohistanis, he would find himself attacked by an enemy in his rear, in fact, between two fires.
