The Battle of Nördlingen (1645) took place on 3 August 1645 in the later stages of the Thirty Years' War, southeast of Nördlingen near the village of Alerheim. A combined Franco-Hessian army led by d'Enghien and Turenne defeated a Bavarian force led by Franz von Mercy. Both sides suffered heavy casualties, with Mercy himself among the dead, but the result had very little strategic impact on the war.
