The Battle of Sahay or Zahájí was fought on 24 May 1742 near village of Zahájí, about 15 km (10 mi) northwest of České Budějovice in southern Bohemia, between the French under the Duc de Broglie and the Austrians under Lobkowicz. The battle was part of the War of the Austrian Succession and was conducted in cooperation with the Prussians under Frederick the Great who had defeated the Austrians a week previously at the battle of Chotusitz. Broglie won a small, but politically important, victory which combined with Frederick's success at Chotusitz disposed Maria Theresa to cede Silesia in the Treaty of Breslau on 11 June 1742.
