He positioned his troops on high ground so the British would basically be attacking up hill, he kept his dragoons in reserve so he launch a rapid counterattack if necessary. He ended up achieving a double envelopment and annihilated Tarleton's force.
The drill manuals of the period are the original source for tactics as the drills were the tactics.
