By daybreak of the 16th the army was in motion. The enterprise before it was arduous in the extreme. After the subtraction of the details necessary to hold the Alumbagh, the Martinière, and the Dilkoosha, there were available for the relief operations only the Ninety-Third, part of the Fifty-Third, two weak Sikh regiments, two provisional battalions of detachments, and portions of the Twenty-Third and Eighty-Second regiments--in all not above three thousand bayonets. Opposed to this handful was a host of some sixty thousand armed men concentrated in a central position of great strength. The task would have been rash even to madness but for Campbell's great strength in artillery, on which he chiefly depended for overcoming the obstacles which interposed between him and the garrison he had come to relieve. That artillery comprised the gallant Peel's naval brigade, consisting of six 24-pounders, two 8-inch howitzers, and two rocket-tubes; the sixteen field-guns of Greathed's column, a heavy and a light field-battery and a mortar-battery of the Royal Artillery, one half field-battery of the Bengal Artillery, and two native Madras horse-artillery guns--in all thirty-nine guns and howitzers, six mortars, and two rocket-tubes. 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
