Henry William Paget, 1st Marquess of Anglesey (17 May 1768 – 29 April 1854), styled Lord Paget between 1784 and 1812 and known as the Earl of Uxbridge between 1812 and 1815, was a British Army officer and politician. After serving as a member of parliament for Carnarvon and then for Milborne Port, he took part in the Flanders Campaign and then commanded the cavalry for Sir John Moore's army in Spain during the Peninsular War; his cavalry showed distinct superiority over their French counterparts at the Battle of Sahagún and at the Battle of Benavente, where he defeated the elite chasseurs of the French Imperial Guard. During the Hundred Days he led the charge of the heavy cavalry against Comte d'Erlon's column at the Battle of Waterloo. At the end of the battle, he lost part of one leg to a cannonball. In later life he served twice as Master-General of the Ordnance and twice as Lord Lieutenant of Ireland. Background, education and politics He was born Henry Bayley, the eldest son of Henry Bayley-Paget, 1st Earl of Uxbridge and his wife Jane (née Champagné), daughter of the Very Reverend Arthur Champagné, Dean of Clonmacnoise, Ireland.

Paget entered parliament at the 1790 general election as member for Carnarvon, a seat he held until the 1796 general election when his brother Edward was elected unopposed in his place. He then represented Milborne Port from 1796 until he resigned his seat in 1804 by appointment as Steward of the Chiltern Hundreds, and again from the 1806 election to January 1810, when he took the Chiltern Hundreds again. Military career At the outbreak of the French Revolutionary Wars, Paget raised a regiment of Staffordshire volunteers and was given the temporary rank of lieutenant-colonel-commandant in December 1793. As the 80th Regiment of Foot, the unit took part in the Flanders Campaign of 1794 under Paget's command. He was formally commissioned into the British Army as a lieutenant in the 7th Regiment of Foot on 14 April 1795 and received rapid promotion, first to captain in the 23rd Regiment of Foot, also on 14 April 1795, then to major in the 65th Regiment of Foot, on 19 May 1795 and then to lieutenant-colonel in the 80th Regiment of Foot on 30 May 1795.
