The Battle of Hořice (German name: Horschitz) was fought on 27 April 1423, between the Orebites faction of the Hussites and Bohemian Catholics.
Hussites took the high ground and built their wagon fort there.
The Catholic cavalry could not ride up such a steep hill and was forced to dismount.
Žižka's men held the Wagenburg against repeated attacks by dismounted cavalry.
With some cavalry, the Hussites charged downhill and swept Catholic forces from the battlefield.
