Walbach) now intervened, charging the exposed right flank of the 49th. The 49th halted their own advance, reformed line from echelon formation and wheeled back their right. Under heavy fire from the 49th, Pearson's detachment and Jackson's two guns, the dragoons renewed their charge twice but eventually fell back, leaving 18 killed and 12 wounded (out of 130). They had bought time for all but one of the American guns to be removed. Barnes's companies of the 2/89th overtook the 49th and captured the one gun which had become bogged down and been abandoned. It was now about half past four. Almost all of the American army was in full retreat. The 25th U.S. Infantry under Colonel Edmund P. Gaines and the collected boat guards under Lieutenant Colonel Timothy Upham held the ravine for a while, but Pearson threatened to get around their left flank, and they, too, fell back. As it was growing dark and the weather was turning stormy, the British halted their advance. The American army meanwhile retreated in great confusion to their boats and crossed to the south (American) bank of the river, although the British did not stand down from battle stations for some time, wary of the Americans renewing the attack. An American witness stated that 1,000 American stragglers had made their way across the river during the battle itself. Casualties Although the British casualties were reported in Morrison's despatches as 22 killed, 148 wounded and 9 missing, it has been demonstrated that a further nine men were killed and an additional four men were missing, giving a revised total of 31 killed, 148 wounded and 13 missing. The American casualties, from the official return, were 102 killed, and 237 wounded including Brigadier General Covington. No figures were given for men missing or captured but the official return notes that three of the sixteen officers listed as wounded were also captured. The number of American prisoners taken was initially reported as "upwards of 100" by Morrison but he wrote that more were still being brought in. The final tally was 120. Most of these were severely wounded men who had been left on the field but fourteen unwounded enlisted men were captured after trying to hide in a swamp. A Canadian who rode across the battlefield on the morning of 12 November remembered it being "covered with Americans killed and wounded". Aftermath On 12
