Within half an hour after the first gun was fired, Porter and Miller had effected their junction within the British lines, had captured Battery No. 2, and moved on Battery No. 1, by the Lake-shore. There the success ended. Battery No. 1 could not be carried. By that time the Royal Scots, the Eighty-ninth, the Sixth, and the Eighty-second British regiments had arrived,--probably about one thousand men.[133] A sharp engagement followed before Brown, after ordering his reserve under Ripley to the assistance of Porter and Miller, could disengage his troops. The three commanders of Porter’s divisions--Gibson, Wood, and Davis--were killed or mortally wounded,--Gibson at the second battery, Davis and Wood in assaulting the shore battery. Ripley was desperately wounded at the same time. General Porter, Lieutenant-Colonel Aspinwall of the Ninth, and Major Trimble of the Nineteenth, as well as a number of other officers, were severely wounded. That the last action was sharp was proved by the losses suffered by the British reinforcements. According to the British official return, the four regiments which came last into the field--the Royal Scots, Sixth, Eighty-second, and Eighty-ninth--lost thirty-six killed, one hundred and nine wounded, and fifty-four missing,--a total of two hundred men, in a short action of half an hour at the utmost, without artillery. The American forces were recalled by Brown and Miller as soon as their progress was stopped, and they retired without serious pursuit beyond the British lines. Their losses were very severe, numbering five hundred and eleven killed, wounded, and missing, or about one fourth of their number. Among them were several of the best officers in the United States service, including Ripley, Wood, and Gibson. Drummond’s loss was still more severe, numbering six hundred and nine,[134] probably almost one man in three of the number engaged. The British killed numbered one hundred and fifteen. The Americans reported seventy-nine killed,--sixty regulars, and nineteen militia. The next day Drummond issued a general order claiming a victory over an American force of “not less than five thousand men, including militia;” but his situation, untenable before the sortie, became impossible after it. Three out of six battering cannon were disabled;[135] he had lost six hundred men in battle, and his losses by sickness were becoming enormous. “My effective numbers are reduced to considerably less than two thousand firelocks,” he reported, September 21. Immediately after the sortie, although reinforced by the Ninety-seventh regiment, he made his arrangements to retreat.
