This historical For King and Parliament scenario was written by myself and Andrew Brentnall, with text by Charles Singleton. It depicts the final battle of the first English Civil War, fought near the eponymous Gloucestershire village on 21st March 1646, when the last Royalist field army, led by brave Sir Jacob Astley, was brought to bay by superior Parliamentarian forces.
Requiring just 20 units on a 12 x 8 box battlefield, this is an excellent introductory scenario for For King and Parliament. It is available as a free download.
