Early in 1814, it was clear that
Napoleon was defeated in Europe, and seasoned British veteran soldiers from the
Peninsular War would be redeployed to Canada. The
United States Secretary of War,
John Armstrong Jr., was eager to win a victory in Canada before British reinforcements arrived there. Major General
Jacob Brown was ordered to form the Left Division of the Army of the North. Armstrong intended him to mount an attack on
Kingston, the main British base on
Lake Ontario, with a diversion by militia across the
Niagara River to distract the British. He had drawn up alternative orders for a major attack across the Niagara, possibly as a contingency plan, but probably to mislead the British through deliberate leaks. Brown thought that he was being presented with two possible plans, and was free to choose between them. Although Brigadier General
Edmund P. Gaines tried to persuade Brown to make the attack on Kingston, Brown was unable to gain cooperation from Commodore
Isaac Chauncey (commanding the American naval squadron based at
Sackets Harbor, New York), which he considered essential for such an attack across Lake Ontario. Chauncey was waiting for new warships to be completed in the shipyard at Sackets Harbor and refused to make any move before the middle of July. Brown made the attack across the Niagara the main focus of his forces. At Buffalo, Scott instituted a major training program. He drilled his troops for ten hours every day, using the 1791 Manual of the
French Revolutionary Army. (Prior to this, various American regiments had been using a variety of different manuals, making it difficult to manoeuvre any large American force). Scott also purged his units of any remaining inefficient officers who had gained their appointments through political influence rather than experience or merit, and he insisted on proper camp discipline including sanitary arrangements. This reduced the wastage from
dysentery and other enteric diseases which had been heavy in previous campaigns. There was only one major deficiency; Scott had been unable to obtain enough regulation blue uniforms for his men. Although they had been manufactured and sent to the northern theater, they had been diverted to Plattsburgh and Sackets Harbor. The United States Army's commissary general, Callender Irvine, hastily ordered 2,000 uniforms to be made and despatched to Buffalo for Scott's other units, but because there was insufficient blue cloth, short jackets (roundabouts) of gray cloth were used instead. Armstrong suggested that Brown should therefore capture and hold
Fort Erie, opposite Buffalo, while waiting for Chauncey to ready his squadron. Brown assented, but was prepared to push much further than the immediate vicinity of Fort Erie. in
Upper Canada, Major General
Phineas Riall assumed the American forces in the area were drawn from the militia. Late in the day, Scott encountered British defences on the far bank of
Chippawa Creek, near the town of
Chippawa. After a brief exchange of artillery fire, Scott withdrew a few miles to Street's Creek. Here he planned to give his troops a belated
Fourth of July parade the next day, while Brown manoeuvred other units to cross the Chippawa upstream. Opposed to Scott was the Right Division of the
British Army in Upper Canada, under Major General
Phineas Riall. Riall believed that Fort Erie was still holding out, and the Americans would therefore have detached large numbers of troops to mask it, leaving only 2,000 men to face his division. He may also have believed that his opponents were militia but was comparatively new to command in Canada and relied on information from Lieutenant Colonel
John Harvey, the deputy
adjutant general for the forces in Upper Canada, that even the United States regulars were of poor quality. Riall determined to cross the Chippawa River and mount an attack to drive the Americans back across the Niagara and relieve Fort Erie. ==Battle==
