The Battle of Stadtlohn was fought on August 6, 1623 between the armies of Christian of Brunswick and of the Catholic League during the Thirty Years' War. The League's forces were led by Johann Tserclaes, Count of Tilly.
On the afternoon of August 6, Christian was forced to turn and fight just outside the village of Stadtlohn in Westphalia, a little over five miles short of the Dutch border. Taking position on a hill, Christian's forces withstood lengthy bombardment before an attack by Tilly's cavalry engulfed Christian's right flank, leading his own cavalry to break and rout. On this sight, the infantrymen also attempted to flee. Tilly's forces swept upon their retreating enemies, killing some 6,000 and capturing 4,000 more as prisoners of war. Among the losses were 50 of Christian's highest ranking officers, and all of his artillery and ammunition. Christian himself escaped, together with 2,000 cavalrymen. Tilly's army suffered 1,000 casualties. A thousand of the prisoners of war enlisted in Tilly's army, but most deserted when they found standards of discipline higher than they had become used to in Christian's army.
The captured artillery pieces were displayed on the marketplace in Coesfeld, and some of the enemy wounded were conveyed to MĂŒnster for treatment. It was reported that many of those fleeing who managed to evade their enemies, fell victim to the ill-will of the peasantry.
