The English Civil Wars, between 1642 and 1651, were a series of political machinations between parliamentarians - the round heads - and royalists - the gentlemen -, mainly over the form of governance in England and issues of religious freedom. The Battle of Naseby took place on Saturday, June 14, 1645, during the First English Civil War. The New Model Parliamentarian army, commanded by Thomas Fairfax and Oliver Cromwell, destroyed the main Royalist army under the command of Charles I and Prince Rupert. In the battle simulation I will try to correct the failures presented in the historical analysis, testing improvements in the maneuvers. And then we will see which maneuver will prevail, both being instructed with the best and with the maximum effort.
