The Siege of Colchester ends when Royalists Forces surrender to the Parliamentary Forces after eleven weeks, during the Second English Civil War.
The siege of Colchester occurred in the summer of 1648 when the English Civil War reignited in several areas of Britain. Colchester found itself in the thick of the unrest when a Royalist army on its way through East Anglia to raise support for the King, was attacked by Lord-General Thomas Fairfax at the head of a Parliamentary force. The Parliamentarians' initial attack forced the Royalist army to retreat behind the town's walls, but they were unable to bring about victory, so they settled down to a siege. Despite the horrors of the siege, the Royalists resisted for eleven weeks and only surrendered following the defeat of the Royalist army in the North of England at the Battle of Preston (1648).
