Musketeers are armed with either a matchlock or doglock musket. In a Civil War regiment of foot they tended to be 2/3rds of the total number of men. Muskets were muzzle loading weapons which fired a 3/4oz lead ball. The injuries inflicted by these projectiles were terrible; as one observer noted at the first battle of Newbury: 'It was somewhat dreadful ... to wipe the brains and bowels from our faces as we advanced...' The English Civil War (1642–1651) was between Roundheads & Cavaliers.
