The line of Campbell's advance was from his extreme right along the right bank of the river for about a mile, and then by a narrow and tortuous lane through thickly-wooded enclosures and between low mud-houses until the vicinity of the rear of the Secundrabagh should be approached. A strong advance-guard of cavalry with Blunt's troop of Bengal Horse Artillery and a company of the Fifty-Third led the way. Hope's and Russell's brigades followed, the ammunition and engineer park came next, and Greathed's brigade brought up the rear. After passing the village of Sultangunge the lane by which the force was advancing turned sharp to the left, when the rear of the Secundrabagh became immediately visible, from the loopholes in which and from the adjacent huts on either side of the lane came a brisk fire. The moment was extremely critical; for the movement in advance was checked, while the cavalry, jammed and helpless in the narrow lane, hindered the passage forward of the artillery and infantry. Sir Colin pushed to the front regardless of the enemy's fire, thrust the cavalry into the side alleys of the village, and ordered a company to line and cover the continuation of the lane passing along the west side of the Secundrabagh and debouching into the open space in its front. He himself then brought up to the front of the building two of Travers' 18-pounders, which promptly set about battering a breach in the south-west bastion of the Secundrabagh. Blunt's troop of horse-artillery came tearing up at a gallop through a heavy cross-fire till it reached the open space between that building and the serai a couple of hundred yards to the southward. Blunt gallantly maintained his fire in three different directions, sustaining heavy losses in men and horses. The Ninety-Third now coming up, three companies of that regiment cleared the serai and the adjacent buildings, drove out the enemy holding those positions, and pursuing the rebels across the plain seized and held the barracks while part of the Fifty-Third in skirmishing order connected that post with the main attack against the Secundrabagh. Sir Colin was near one of Blunt's guns when a bullet which had passed through a gunner struck him with great force on the thigh, but it did not penetrate and he escaped with a severe bruise.
