The Siege of Exeter took place during the First English Civil War, from 18th November 1642 to 4th January 1643. During this period, a Parliamentary garrison frustrated two attempts to capture the city by Royalists under Sir Ralph Hopton. Although much of the West Country was strongly Royalist, the ports of Exeter and Plymouth were controlled by Parliament, hindering the import of vital military supplies. From October 1642 to January 1643, the Royalists made several efforts to take one of them. When Hopton arrived at Exeter on 18 November, he found it occupied, and withdrew. In late December, he made a more serious attempt, before retreating on 4 January. Following a series of victories in summer 1643, the Royalists captured Exeter on 6 September; it remained in their possession until April 1646. (Wikipedia).
