Soon after his capture he was exchanged, and promoted to the rank of colonel. He joined the American armies as chief of staff to the major-general commanding, and being about the only man in the army who had any knowledge of tactical manuals and military treatises generally, he was kept busy from morning till night in organizing the staff service, drilling the officers, and the like. These duties, however, did not interfere with his leading and commanding his troops in battle. He led the advance guard in the successful assault on Fort George in May, 1813, took part in a number of skirmishes, and served with gallantry in Wilkinson's unsuccessful campaign. Early in the spring of 1814 a camp of instruction for officers and men was formed, with Scott in command, near Buffalo. Up to this time the imbecility of the administration (and of the people whom the administration represented) in not preparing for the war, had been well matched by the supineness with which they carried it on. During the eighteen months that had elapsed since the beginning of the contest, only the navy, built by the Federalists when in power fifteen years before, had saved the country from complete disgrace, the armies generally being utterly inadequate in number, and moreover models of all that troops ought not to be. Even in 1814 this remained true of the forces intrusted with the defence of the Capital itself; but on the northern frontier Scott, and his immediate superior, Brown, by laborious work succeeded in turning the inefficient mob of the first two campaigns into as admirable a weapon of offence and defence as ever was handled by a general officer. In July the little army of skeleton regiments, thus carefully drilled, was ready for the invasion of Canada. On July 5th the fight at Chippewa took place. The battle was practically between Scott's wing of Brown's army and Riall's British troops, the numbers being almost exactly equal. There was very little manoeuvring. After a tolerably heavy artillery fire and some skirmishing between the light troops and Indians on each side, in the woods, the British regulars and Scott's American regulars advanced against each other in line across the plain, occasionally halting to fire. It was noticed that the fire of the Americans was the more deadly; their line was thinner and more extended than that of the British. When within sixty or seventy paces of one another the two sides charged; there was a clash of bayonets; then the thinner American line, outflanking the more solid British column, closed in at the extremities, and the British broke and fled immediately.
