During the early part of the advance the Afghans collected in great strength on the low hills beneath the Baba Wan Kotal, evidently preparing for a rush on our guns; their leaders could be seen urging them on, and a portion of them came down the hill, but the main body apparently refused to follow, and remained on the crest until the position was turned, when they at once retreated.
Having become assured of General Ross's complete success, and seeing that there was now no necessity for detaining Macgregor's (the 3rd) brigade to meet a counter-attack, I pushed on with it to join Ross, who, however, knowing how thoroughly he could depend upon his troops, without waiting to be reinforced, followed up the retreating foe, until he reached an entrenched position at the other side of the Baba Wali Kotal, where the Afghans made another most determined stand. Ghazis in large numbers flocked to this spot from the rear, while the guns on the kotal were turned round and brought to bear on our men, already exposed to a heavy Artillery fire from behind the entrenched camp.
92nd Highlanders and 2nd Gurkhas It now became necessary to take this position by storm, and recognizing the fact with true soldierly instinct, Major White, who was leading the advanced companies of the 92nd, called upon the men for just one charge more 'to close the business.' The battery of screw guns had been shelling the position, and, under cover of its fire and supported by a portion of the 2nd Gurkhas and 23rd Pioneers, the Highlanders, responding with alacrity to their leader's call, dashed forward and drove the enemy from their entrenchments at the point of the [bayonet].[3]
Major White was the first to reach the guns, being closely followed by Sepoy Inderbir Lama, who, placing his rifle upon one of them, exclaimed, 'Captured in the name of the 2nd (Prince of Wales' Own) Gurkhas!'
Whilst the 1st Brigade was advancing towards the last position, a half-battalion of the 3rd Sikhs (belonging to the 2nd Brigade), under Lieutenant-Colonel G. Money, charged a body of Afghans and captured three guns.
Ayub Khan's Camp The enemy were now absolutely routed, but, owing to the nature of the ground, it was impossible for General Ross to realize how complete had been his victory, and he fully expected that the enemy would take up a fresh position further on; he therefore ordered the 1st and 2nd Brigades to halt while they replenished their ammunition, and then proceeded for about a mile, when they suddenly came in sight of Ayub Khan's enormous camp. It was entirely deserted, and apparently stood as it had been left in the morning when the Afghans moved out to the attack. With his camp was captured the whole of Ayub Khan's Artillery, thirty-two pieces, including our two Horse Artillery [guns][4] which had been taken at Maiwand on the 27th July.
Further pursuit by the Infantry being valueless, the 1st and 2nd Brigades halted on the far side of Mazra, where I with the 3rd Brigade shortly afterwards joined them.
Brigadier-General Hugh Gough, having satisfied himself as to the security of our left flank, scouted as far as Kohkeran, and then proceeded with the Cavalry of the Kabul-Kandahar Field Force to execute the extended movement entrusted to him. He crossed the Arghandab, and pushed round to get in front of the line of the enemy's retreat towards Khakrez. Some ghazis and Irregular Afghan troops were overtaken, but no Regular regiments were met with, the soldiers having, as is their custom, quickly divested themselves of their uniform and assumed the garb of harmless agriculturists.
Ayub Khan himself had fled early in the day with his principal Sirdars.
As I rode into the abandoned camp, I was horrified to hear that the body of Maclaine, the Horse Artillery officer who had been taken prisoner at Maiwand, was lying with the throat cut about forty yards from Ayub Khan's own tent. From what I could learn, the latter had not actually ordered the murder, but as a word from him would have prevented it, he must be held responsible for the assassination of an officer who had fallen into his hands as a prisoner of war.
