When Mansfeld was on his way to reinforce general Hohenlohe, who was besieging České Budějovice, Bucquoy intercepted Mansfeld near the small village of Záblatí (German: Sablat), about 25 km (16 mi) km northwest of České Budějovice, and brought him to battle. Mansfeld suffered defeat, losing at least 1,500 infantry and his baggage train. As a result, the Bohemians had to lift the siege of České Budějovice.
