When Drummond, hurrying across from York, landed at Fort Niagara in the early morning of the fateful 25th, he found that the orders he had sent over on the 23rd were already being carried out, though in a slightly modified form. Colonel Tucker was marching off from Fort Niagara to Lewiston, which he took without opposition. Then, first making sure that the heights beyond were also clear, he crossed over the Niagara to Queenston, where his men had dinner with those who had marched up on the Canadian side from Fort George. Immediately after dinner half the total sixteen hundred present marched back to garrison Forts George and Niagara, while the other half marched forward, up-stream, on the Canadian side, with Drummond, towards Lundy's Lane, whither Riall had preceded them with reinforcements for the advanced guard under Colonel Pearson. In the meantime Brown had heard about the taking of Lewiston, and, fearing that the British might take Fort Schlosser too, had at once given up all idea of his diagonal march on Burlington and had decided to advance straight against Queenston instead. Thus both the American and the British main bodies were marching on Lundy's Lane from opposite sides and in successive detachments throughout that long, intensely hot, midsummer afternoon. Presently Riall got a report saying that the Americans were advancing in one massed force instead of in successive detachments. He thereupon ordered Pearson to retire from Lundy's Lane to Queenston, sent back orders that Colonel Hercules Scott, who was marching up twelve hundred men from near St Catharine's on Twelve Mile Creek, was also to go to Queenston, and reported both these changes to Drummond, who was hurrying along the Queenston road towards Lundy's Lane as fast as he could. While the orderly officers were galloping back to Drummond and Hercules Scott, and while Pearson was getting his men into their order of march, Winfield Scott's brigade of American regulars suddenly appeared on the Chippawa road, deployed for attack, and halted. There was a pause on both sides. Winfield Scott thought he might have Drummond's whole force in front of him. Riall thought he was faced by the whole of Brown's. But Winfield Scott, presently realizing that Pearson was unsupported, resumed his advance; while Pearson and Riall, not realizing that Winfield Scott was himself unsupported for the time being, immediately began to retire.
