In the fast paced battlefields of the the Reiters were a swift strike force of blazing pistols. A staple of many armies from the late 16th century to early decades of the 17th century the Reiters were light cavalry with a special flourish.
They developed a special tactic where they would charge towards the enemy, and let blast with their pistols at near point blank range.
They would then wheel away from the enemy, returning towards their lines, reload and repeat the maneuver. When the enemy was suitably weakened they would finish them off with a sword melee.
These are metal 25mm pieces from Hinchcliffe that I painted in the late 1970's.
