Lieutenant-General Sir Philip Bainbrigge CB (1786–1862) was a British Army officer. He was present at the sieges and storming of Ciudad Rodrigo and Badajoz, and later the advance to Madrid. He later joined the British army in its advance to Paris, and held positions in Belfast and Ceylon. He was created a Knights Commander of the Order of the Bath and died at St. Margaret's in 1862.
Bainbrigge was descended from an ancient family long resident in the counties of Leicester and Derby. He was the eldest son of Lieutenant-colonel Philip Bainbrigge, of Ashbourne, Derbyshire, and Rachel, daughter of Peter Dobree, Esq., of Beauregard, Guernsey, and was born in London in 1786. He entered the navy as a midshipman in the Caesar, under Admiral Sir James Saumarez, in 1799, but left it from ill-health. His father, who served under the Duke of York in the expedition to Holland, was killed in the attack on Egmond aan Zee on 6 October 1799, and the next year the duke appointed young Bainbrigge to an ensigncy in the 20th regiment.
In 1800 he became a lieutenant, but being fourteen years of age, he obtained a year's leave, which he spent at Green's military academy at Deptford, and joined his regiment at Malta in 1801. At the peace of Amiens his regiment was reduced and he was placed on half-pay, but was brought on full pay into the 7th fusiliers. Returning to England in 1803, he was employed in obtaining volunteers from the militia to form the 2nd battalion of the 7th, which when completed was removed to Colchester. Here the troops were reviewed by the Duke of York, and Lieutenant Bainbrigge, who by his zeal and diligence had given much satisfaction, was gazetted, on 17 Oct. 1805, to a company in the 18th Royal Irish, and joined the 1st battalion of the regiment in the West Indies.
