Santa Anna was angered by Valencia's disobedience, but nonetheless sought to save his army. He moved with Brigadier General Francisco Pérez's 3,000 man brigade to San Ángel, just north of the fighting. Night brought a cold rain and the end of fighting for the day. The American forces had positioned themselves to block Santa Anna's approach to Valencia's army. Santa Anna wanted to fall back in an orderly fashion and ordered Valencia to abandon his artillery and retreat with his men and their smaller weapons. Valencia refused to obey the order.
