I was thoroughly well acquainted with the ground comprised in the theatre of the proposed operations, having frequently ridden over it during the preceding two months; I was thus able to calculate to a nicety the difficulties each column would have to encounter and the distances they would have to cover, and arrange with the utmost precision the hour at which each Commander should move off to insure a timely junction.

So that when I left Sherpur at ten o'clock on the 11th December to take command of Macpherson's and Massy's columns as soon as they should unite, I had no misgivings, and was sanguine that my carefully arranged programme would result in the discomfiture of Mahomed Jan; but the events which followed on that day afforded a striking exemplification of the uncertainty of war, and of how even a very slight divergence from a General's orders may upset plans made with the greatest care and thought, and lead to disastrous results.
Massy could not have clearly understood the part he was meant to take in co-operation with Macpherson, for instead of following the route I had directed him to take, he marched straight across country to the Ghazni road, which brought him face to face with the enemy before he could be joined by Macpherson.

In his explanatory report Massy stated that he had been misled by a memorandum[9] which he received from the Assistant Adjutant-General after his interview with me (although this memorandum contained nothing contradictory of the orders I had given him); that he understood from it that his business was to reach the Ghazni road at its nearest point in the direction of Arghandeh, and that he thought it better, with a thirty miles' march in prospect, to take the most direct line in order to save his horses, to economize time in a short December day, and to keep as near as he could to the column with which he was to co-operate; further, he stated that he was under the impression there was little likelihood of his meeting with any of the enemy nearer than Arghandeh.
On starting from Aushar Massy detached a troop of the 9th Lancers to communicate with Macpherson.

This reduced his column to 247 British and 44 Native Cavalry, with 4 Horse Artillery guns.
As the party moved along the Chardeh valley, a loud beating of drums was heard, and Captain Bloomfield Gough, 9th Lancers, commanding the advance guard, perceived when he had moved to about a mile north of Kila Kazi, that the enemy were occupying hills on both sides of the Ghazni road, about two miles to his left front, and sent back word to that effect.

Massy, not believing that the Afghans had collected in any considerable numbers, continued to advance; but he was soon undeceived by the crowds of men and waving standards which shortly came into view moving towards Kila Kazi.
