celebrating Saint Andrew's Day and as the attack was under way, the Spanish troops sounded a trumpet reveille, which the Mapuche forces took as an alarm; their belief that they had been discovered caused the attack to be ruined. There were 15,000 attackers, among which Galvarino was included, who went in front, appearing with his severed arms and inciting the passions of his comrades. The battle of Millarapue lasted from the early morning until 2 PM the following day, and Caupolican directed it from atop a white horse.

When almost the entire army was already inside the fort, they were received with rounds of gunfire that caused a high number of casualties among the attackers, who escaped in a disorganized fashion. Caupolican was able to flee thanks to the fact that the Spanish cavalry had
