British military leadership, which had been decisive up to Brock's death, suffered a blow with his loss. Brock's direct successor, Major-General Sheaffe, although successful in his approach at Queenston Heights, was never able to live up to Brock's reputation. He was criticized by many, including influential clergyman [[John Strachan]], for his retreat at the [[Battle of York]] in April 1813. Sheaffe was shortly afterwards recalled to England, where he continued a successful, if not brilliant, military career.{{sfn|Whitfield|Turner|1985}}

In 1813, Brock's successor at Detroit, Colonel [[Henry Procter (general)|Henry Procter]], faced an attack from the reconstituted [[Army of the Northwest (United States)|Army of the Northwest]] under Brigadier General [[William Henry Harrison]]. Harrison set out to retake Detroit, but the column led by his second-in-command, Brigadier General [[James Winchester (general)|James Winchester]], was defeated at the [[Battle of Frenchtown]] on 22 January 1813. Procter, displaying poor judgement, left several dozen wounded prisoners behind when the British withdrew. The prisoners were subsequently massacred by some of Procter's Indigenous allies.{{sfn|Hitsman|Graves|1999|p=126}} Following the American naval victory at the [[Battle of Lake Erie]] on 10 September 1813, Procter's supply lines were cut, and he and Tecumseh were forced to hastily retreat from Detroit and Amherstburg. Harrison caught up with Procter near Moraviantown on the [[Thames River (Ontario)|Thames River]], leading to the [[Battle of the Thames]] on 5 October 1813. Following a frontal attack by mounted riflemen the British retreated in disorder. Procter and about 246 of his men escaped while the rest of his soldiers surrendered. Tecumseh continued fighting but was fatally wounded.{{sfn|Hitsman|Graves|1999|p=173-176}} Procter was later court-martialed and reprimanded. He returned to England in 1815 and lived in semi-retirement until his death in 1822.<ref>{{cite encyclopedia |last=Hyatt |first=A. M.

Lieutenant General Sir George Prévost, who often clashed with Brock, remained in control of British forces in North America until the end of the war, but was relieved of command immediately afterwards in consequence of his conduct during the September 1814 [[Battle of Plattsburgh]]. The battle was intended to be a joint naval and infantry attack, but Prevost failed to commit his land forces until the naval battle was nearly over. When he finally did advance, his forces were unable to cross the [[Saranac River]] bridge. Despite a heavy advantage in manpower, Prevost retreated upon hearing of the failure of the naval attack.  Prevost was later recalled to England to face an inquiry. It was determined that the blame for the loss primarily rested with Prevost. Prevost's health failed him, and he died in early 1816.{{sfn|Burroughs|1983}}
