Manley Power and two other successful Peninsular War veteran brigade leaders,
Thomas Brisbane and
Frederick Philipse Robinson, were sent to bolster British forces in the
War of 1812 in North America (and therefore did not participate in the
Battle of Waterloo). The veteran brigade leaders were deeply disappointed by Sir
George Prevost's caution at the
Battle of Plattsburgh. Prevost had placed
Francis de Rottenburg in charge of infantry, with the brigades under his command (Power with 3500, Brisbane with 3500, and Robinson with 2500 troops). The brigade leaders were dismayed with the decision to withdraw from battle because they felt they could have easily captured Plattsburgh despite the unsuccessful British naval action. Their opinions carried significant weight in Britain, which led to the removal of Prevost as
Commander-in-Chief, North America. The
Duke of Wellington wrote on 30 October 1814, It is very obvious to me that you must remove Sir George Prevost. I see he has gone to war about trifles with the general officers I sent him, which are certainly the best of their rank in the army; and his subsequent failure and distresses will be aggravated by that circumstance; and will probably with the usual fairness of the public be attributed to it. In December, Wellington's former Quartermaster General, Sir
George Murray, was sent to Canada with the local rank of lieutenant-general, specifically to order Prevost to return to London to explain his conduct of the Plattsburg campaign. Another Peninsular War veteran and Manley Power's previous commanding officer, Sir Edward Pakenham, became the commander of the British North American army. Manley Power took part in the
Battle of New Orleans, where Pakenham was killed, which unbeknown to its participants occurred after the
Treaty of Ghent was signed in
Belgium, but it did not take effect until it was ratified by the United States in February 1815. ==Occupation of France==
