High Quality Content by WIKIPEDIA articles! Colin Campbell Mitchell (17 November 1925 – 20 July 1996) was a British Army lieutenant-colonel and politician. He became famous in July 1967 when he led the Argyll and Sutherland Highlanders in the British reoccupation of the Crater district of Aden. At that time, Aden was a British colony and the Crater district had briefly been taken over by nationalist insurgents. Mitchell became widely known as “Mad Mitch”. His reoccupation of the Crater became known as "the Last Battle of the British Empire". Although some observers questioned whether the Last Battle was ever worth fighting, the event marked the end of an era in British history and made Mitchell an iconic figure.
