Thomas Cochrane, 11th Earl of Dundonald

Captain Thomas Barnes Cochrane, 11th Earl of Dundonald (14 April 1814 – 15 January 1885) was a British Army officer and politician. He was the son of the radical politician and sailor Thomas Cochrane, 10th Earl of Dundonald. As a child he accompanied his father to Chile as a stowaway on the Chilean frigate O'Higgins. In February 1819 the O'Higgins attempted to raid the city of Callao, but was repelled by the coastal fortresses. Thomas Cochrane was almost hit by a cannonball, which instead killed a sailor next to him.

Cochrane joined the British army and eventually rose to the rank of captain. On 31 October 1860, he succeeded his father as the 11th Earl of Dundonald. Between 1879 and 1885, he was a Scottish representative peer.

Thomas's eldest son, Douglas Cochrane learnt of his father's death when he was serving at the Desert March and the Relief of Khartoum.
