The Commander-in-Chief desired judicious speed, and the operations were hurried on unduly by men who were too impetuous to adhere to the scheme sanctioned by their chief. After a four days' bombardment of the place the assault was ordered for the early morning of the 25th. The storming-party consisted of a battalion of the Royals, with the task of carrying the great breach; of the Thirty-Eighth, told off to assail the lesser breach further to the right; and of the Ninth, to act in support of the Royals. Colin Campbell had a special position and a special duty, of a kind seldom entrusted to a subaltern and markedly indicative of the estimation which he had thus early earned. He was placed in the centre of the Royals with twenty men of his (the light) company, having the light company of the Royals as his immediate support and under his orders, and accompanied by a ladder-party under an engineer officer. His specific orders were on reaching the crest of the breach to gain the ramparts on the left, sweep the curtain to the high work in the centre of the main front, and there establish himself. The signal for an advance to the assault was given prematurely, while it was still dark, by the explosion of a mine, and the head of the storming-party moved out of the trenches promptly but in straggling order. The space between the exit from the parallel and the breach, some three hundred yards, was very rugged, broken by projecting rocks, pools, seaweed and other impediments. These difficulties, the darkness, and the withering fire from the ramparts, increased the tendency to disorder, and presently Campbell was not surprised to find an actual check. The halted mass had opened fire and there was no moving it forward. He pushed on past the halted body having there lost some men of his detachment; and reached the breach, the lower part of which he observed to be thickly strewn with killed and wounded. "There were," to quote from his journal, "a few individual officers spread on the face of the breach, but nothing more. These were cheering, and gallantly exposing themselves to the close and destructive fire directed on them from the round tower and other defences. In going up I passed Jones of the Engineers[1] who was wounded; and on gaining the top I was shot through the right hip and tumbled to the bottom. Finding on rising that I was not disabled from moving, and observing two officers of the Royals who were exerting themselves to lead some of their men from under the line-wall near to the breach, I went to assist their endeavours and again went up the breach with them, when I was shot through the inside part of the left thigh." In the language of the brilliant historian of the Peninsular War--"It was in vain that Lieutenant Campbell, breaking through the tumultuous crowd with the survivors of his chosen detachment, mounted the ruins--twice he ascended, twice he was wounded, and all around him died." The assault failed; and the siege of San Sebastian was
