The Spanish sent a screen of 500 harquebusiers to cover their advance; but soon the two unruly mutineer regiments in the vanguard started the attack with a rash charge up the hill. They were repulsed in disorder, while the light cavalry, counter-charged by the Dutch cuirassiers, were routed. It was then time for the second line of the Spanish infantry to advance. The Sapena and Ávila Tercios made quick progress against the Frisian regiment on the Dutch right, and Maurice sent his entire second line to protect that sector, stabilising the front.
