All was instantly on the alert. The staff went off at speed to bring up the fifth and sixth divisions. The infantry stood to arms, primed and loaded, fixed bayonets, uncased the colours, and abandoning the defensive system, hitherto so admirably employed, prepared for an immediate attack. Pakenham commended the action by advancing in four columns along the valley, assailing the left flank of the enemy, and driving it before him in great confusion. D’Urban’s Portuguese dragoons, and Harvey’s light cavalry (the 14th), protected the flank during the movement, and, when the French became disordered, charged boldly in and sabred the broken infantry. Nothing could be more brilliant than Pakenham’s advance. A level plateau of nearly eight hundred yards was to be crossed before the assailants could reach the heights, whither Fox’s division were marching hastily to occupy the ground. A heavy fire from the French guns was showered on the advancing columns, while the British batteries, under Captain Douglass, replied by a furious cannonade. Wallace’s brigade--the 45th, 74th, and 88th--formed the first line, and moved forward in open column. The face of the height was covered with tirailleurs, who kept up an incessant fusilade, while grape and canister ploughed the ground, occasioning a heavy loss, and more particularly to the centre. They suffered, but they could not be checked; not waiting to deploy, the companies brought forward their right shoulders in a run, forming line from open column without halting, while the wings of the brigade, having moved up the hill with less impediments than the centre, were more advanced, and the line thus assumed rather the figure of a crescent. All the mounted officers, regardless of a withering fusilade, were riding in front of the battalions, and the men following with their muskets at the rest. At last they reached the brow. Foy’s division, beating the _pas de charge_, advanced, and threw in a murderous volley. Half the British front rank went down. Staggered by that deadly fire, the brigade recoiled a step or two, but, instantly recovering, the rear rank filled the places of the fallen. On it went with imposing steadiness, regardless of the irregular fusilade, for the French continued to pour in their fire with more rapidity than effect.
