The Prussian 31st Brigade, part of the Elbe Army, started the battle and attacked Klaster making the 38th Austrian Regiment, consisting out of Venetians, to rapidly abandon their position on the hill.

In the north, Prince Frederick Charles attacked the north side of Musky Hill with his Prussian 8th Division, under Horn, where they encountered Piret and Abele, while the Prussian 7th Division, under Fransecky, marched through the morass behind the heights to cut the Austrian communication lines to Mnichovo Hradiště and Jičín.

Seeing the danger of being encircled, Leiningen ordered his brigade to withdraw from the town.

Abele's brigade held long enough on the slopes of the hill for Leiningen and Piret to untangle and the Austrian brigades escaped to the east, leaving some 3,000 men in killed, wounded and prisoners.

The Prussians, having only engaged with 14 battalions, only lost about 300 men, but managed to link up their two armies and drive the Austrians and their Saxon allies out of their Iser line.
