The Thirty Years War of 1618 to 1648 is considered one of the most destructive wars in European history. It is estimated that between 4.5 and 8 million soldiers and civilians died as a direct result, while some areas of Germany suffered population declines of more than 50%, also from famine and disease. The war was part of the German religious struggle that was initiated by the Protestant Reformation of the 16th century. At the battle of Alerheim on August 3, 1645, the French army took from noon until 4 pm to organize its battle line. The only French gain from the bloody victory was the capture of Nördlingen and Dinkelsbühl. Eventually, the battle only provided Bavaria with breathing space and did not prevent its invasion the following year. In the battle simulation I will try to correct the flaws presented in the historical analysis, testing improvements in maneuvers. And then we will see which maneuver will prevail, with both of us instructed with the best and with maximum effort.
