light infantry to harass or disorder the American line, or to locate any weak points in it. The Americans beat back the attack after a short-range musketry duel over the abandoned British guns, in which both sides suffered heavy casualties. The Glengarry Light Infantry, who had once again begun to harass the American left flank, were mistaken for Americans by other British units and forced to withdraw after suffering casualties from British fire. Undeterred by his first failure, Drummond launched a second attack, using the same methods and formation as in the first. Although some American units wavered, they were rallied by Ripley and stood their ground. While the combat was taking place, Winfield Scott led his depleted brigade (which had been reorganized into a single ad hoc battalion under Major Henry Leavenworth) in an unauthorized attack against Drummond's centre. Scott's brigade was engaged both by the British and by units of Ripley's brigade, who were not aware of the identity of the troops at which they were shooting. Drummond's line was driven back but Scott's men broke in disorder and retreated, before rallying on the American left. Scott rode to join Jesup's regiment, still out on the right flank, but was severely wounded shortly afterwards. Shortly before midnight, Drummond launched a third counter-attack, using every man he could find, although by this time the British line consisted of mixed-up detachments and companies, rather than organized regiments and battalions. The fighting over the artillery was closer than before, with bayonets being used at one point, but again the exhausted British fell back. End of the battle By midnight both sides were spent. On the American side only 700 men were still standing in the line. Winfield Scott and Jacob Brown were both severely wounded. Brown would soon recover but Scott's injury removed him from the campaign. With supplies and water short, Brown ordered a retreat. Porter and Lieutenant Colonel Jacob Hindman (Brown's artillery commander) protested but complied. Ripley apparently did not learn of Brown's order until he realised that Hindman's artillery had been withdrawn. Although urged by Porter to maintain his position, he also withdrew. The British still had 1,400 men on the field but they were in no condition to interfere with the American withdrawal. Drummond had ordered some units to hold the Portage Road and left some light infantry outposts near the Americans, but had withdrawn the remainder
