During the English Civil War, Newark was a mainstay of the royalist cause, Charles I having raised his standard in nearby Nottingham. "Newark was besieged on three occasions and finally surrendered only when ordered to do so by the King after his own surrender. It was attacked in February 1643 by two troops of horsemen, but beat them back. The town fielded at times as many as 600 soldiers, and raided Nottingham, Grantham, Northampton, Gainsborough and other places with mixed success, but enough to cause it to rise to national notice. At the end of 1644 it was besieged by forces from Nottingham, Lincoln and Derby until relieved in March by Prince Rupert. (Wikipedia article)
The Relief of Newark (21 March 1644) was a Royalist victory during the First English Civil War. It was a personal victory for Prince Rupert of the Rhine, and it resulted in the Royalists holding Newark-on-Trent until very near the end of the war. (Wikipedia article).
