Brent Spencer

General Sir Brent Spencer GCB (1760 – 29 December 1828) was an officer in the British Army during the American Revolutionary War and French Revolutionary Wars. During the Peninsular War he became Lord Arthur Wellesley's second-in-command on two occasions. He fought at Vimeiro and testified in Wellesley's favor at the inquiry following the Convention of Cintra. He led a division at Bussaco and two divisions at Fuentes de Onoro. After the latter action, he had an independent command in northern Portugal. Wellesley, now Lord Wellington, was not satisfied that Spencer was up to the responsibilities of second-in-command and he was replaced by Thomas Graham. Miffed, Spencer left Portugal and never returned. He became a full general in 1825.

He was the Member of Parliament (MP) for Sligo Borough from 1815 to 1818.

Spencer became a commissioned officer in 1778. He fought with great credit in the West Indies in 1779–1782 during the American Revolutionary War and again in 1790–1794 during the War of the First Coalition. Promoted to brigadier general, he participated in the unsuccessful 1797 Santo Domingo campaign against Toussaint Louverture. In 1799, he led the 40th Foot during the Anglo-Russian invasion of Holland. This campaign included the battles of Bergen and Castricum.
