Second Battle of Nördlingen
The second Battle of Nördlingen (or Battle of Allerheim) was fought on August 3, 1645 southeast of Nördlingen near the village of Alerheim.
France and its Protestant German allies defeated the forces of the Holy Roman Empire and its Bavarian Catholic league allies.
Despite Königsmarck’s detaching himself from the Franco-Hessian armies, the Bavarians were still considerably outnumbered. Nonetheless, they determined to give battle to the French at Alerheim, near Nördlingen.
There, on 3 August, 1645, the Bavarians were driven from the field in a bloody battle that cost the life of the Bavarian general Mercy. The conflict left the French too weakened to follow up on their advantage, although they did occupy Nördlingen.
