The Battle of Sablat or Záblatí occurred on June 10, 1619, during the Bohemian period of the Thirty Years' War. The battle was fought between the Roman Catholic army of Karel Bonaventura Buquoy and the Protestant army of Ernst von Mansfeld.
When Mansfeld was on his way to reinforce general Hohenloe, who was besieging Budějovice, Buquoy intercepted Mansfeld near the small village of Záblatí (German: Sablat) 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 Budějovice.
