About the end of June, the Americans concentrated at Buffalo, Black Rock, and other places, on the Niagara frontier, for the invasion of Upper Canada, only waited for the co-operation of the fleet, which had not, as yet, come out of Sackett's Harbour. The army was commanded by General Brown, however, an officer, of considerable judgment, and now not by any means inexperienced in the art of war, who could not remain long inactive. On the 3rd of July, he despatched Brigadiers Scott and Ripley, with their two strong brigades, to effect a landing on the Canada shore. They landed from boats and batteaux, at two different points. One brigadier landed above Fort Erie, and the other below it, the brigades being two miles apart, and the fort in the centre. Captain Buck, of the 8th regiment, was in command of Fort Erie, and, oddly enough, although he had put it in a tolerably good state for defence, he at once surrendered it, and his garrison of seventy men, to the enemy. Scott and Ripley now marched on Chippewa, and were making preparations to carry that post when they were met by General Riall, with fifteen hundred regular troops, and a thousand Indians and militia, and offered battle. The offer was no sooner made than accepted, and at five in the afternoon, a battle was commenced, which proved disastrous to Riall. The enemy were overwhelmingly numerous. Riall's militia and Indians attacked the American light troops vigorously, but they were unable to cope with Kentucky riflemen, sheltered behind trees. Death came with every rifle flash, and the militia and Indians must have given way, had not the light companies of the Royal Scotts and 100th regiments come to their relief. Now came the main and, on the part of Riall, ill-judged attack. He concentrated his whole force, while the Americans stretched out in line. He approached in column, attempting to deploy under a most galling fire, and the result was, as might have been anticipated, fearfully disastrous. With 151 men killed and 320 wounded, among whom was Lieutenant-Colonel, the Marquis of Tweedale, the British were compelled to retire. Riall's object in retiring was to gain his intrenched camp, but General Brown, who now commanded the Americans, discovered a cross road, and Riall, abandoning Queenston, fell back to Twenty Mile Creek. The loss of the Americans was 70 killed and 9 officers and 240 men wounded. This was the most sanguinary of any battle that had been fought during the war, and the enemy, gaining courage, advanced gradually, and made demonstrations upon Forts George and Mississaga. On the 25th of July, Brown, not considering it expedient to advance and, unsafe to stand still, retreated upon Chippewa, the village of St. David's having been previously set on fire, by a Lieutenant-Colonel Stone, whom Brown compelled to retire from the army for his barbarity. General Riall now again advanced, when the enemy wheeled about and endeavoured to cut him off from his expected reinforcement.
