The Battle of Gefrees was fought on 8 July 1809 during the War of the Fifth Coalition between a joint force of Austrians and Brunswickers under the command of General Kienmayer and a French force under the command of General Junot, Duke of Abrantès. The battle ended in victory for the Austrians who avoided being trapped by Junot and a force of Saxons and Westphalians led by Jérôme Bonaparte, King of Westphalia. After Jérôme's troops were defeated at the Battle of Hof, the Austrians effectively had control over all of Saxony. However the victory was in vain, due to the major Austrian defeat at Wagram and the Armistice of Znaim.
