Frederick stopped the bombardment of Prague and maintained the siege under Duke Ferdinand of Brunswick, while the king marched against the Austrians on 13 June along with Prince Moritz of Anhalt-Dessau's troops.

A counterattack by the Austrian right was defeated by Prussian cavalry and Frederick poured more troops into the ensuing gap in the enemy line.

Prussian cuirassiers under Oberst Friedrich Wilhelm von Seydlitz (promoted to major-general on that day) finally showed up.

The battle was Frederick's first defeat in this war, and forced him to abandon his intended march on Vienna, raise his siege of Prague on 20 June, and fall back on Litoměřice.

The Austrians, reinforced by the 48,000 troops in Prague, followed them, 100,000 strong, and, falling on Prince August Wilhelm of Prussia, who was retreating eccentrically (for commissariat reasons) at Zittau, inflicted a severe check upon him.
