The successful action of the 27th had given Sir Redvers Buller possession of the whole of the left and centre of the Pieters position, and in consequence of these large sections of their entrenchments having fallen into British hands, the Boers evacuated the remainder and retreated westward on to the high hills and northward towards Bulwana Mountain. About ninety prisoners were captured in the assault, and more than a hundred bodies were counted in the trenches. After making allowances for the fact that these men were for the most part killed by shell fire, and that therefore the proportion of killed to wounded would necessarily be higher than if the loss were caused by bullets, it seems probable that no less than three hundred wounded were removed. Forty were collected by British ambulance parties. Of the Boers who were killed in the retreat no accurate estimate can be formed, but the dongas and kopjes beyond the position were strewn with occasional corpses. Undoubtedly the enemy was hard hit in personnel, and the fact that we had taken two miles of entrenchments as well as considerable stores of ammunition proved that a very definite and substantial success had been won. But we were not prepared for the complete results that followed the operations of the 27th. Neither the General nor his army expected to enter Ladysmith without another action. Before us a smooth plain, apparently unobstructed, ran to the foot of Bulwana, but from this forbidding eminence a line of ridges and kopjes was drawn to the high hills of Doorn Kloof, and seemed to interpose another serious barrier. It was true that this last position was within range, or almost within range, of Sir George White's guns, so that its defenders might be caught between two fires, but we knew, and thought the Boers knew, that the Ladysmith garrison was too feeble from want of food and other privations to count for very much. So Sir Redvers Buller, facing the least satisfactory assumption, determined to rest his army on the 28th, and attack Bulwana Hill on March 1.
