The Battle of Frohnhofen or Battle of Laufach took place on 13 July 1866 as part of the Main Campaign of the Prussian Army in the Austro-Prussian War. In a battle lasting several hours, the Prussian 26th Infantry Brigade repulsed attacks by the 3rd (Hessian) Division of the VIII. Corps of the North German Confederation , with the Hessians suffering heavy losses. It thus secured the Spessart crossings and created favorable conditions for the Battle of Aschaffenburg around the Main crossing the next day.
