Millarapue also a leader of 6,000 men, but old and not a candidate for the leadership, was the one who persuaded them to quit arguing among themselves and settle the matter with a contest of strength between them which resulted in the victory of Caupolicán who became Toqui.
[2] Lobera later says Colocolo and Peteguelen were the leaders that discovered the advance of the army of Francisco de Villagra and summoned all the people who could fight from the neighboring provinces to oppose the Spanish in the Battle of Marihueñu.
[5] Lobera also says he was one of the major leaders of the Arauco area to submit to Mendoza after the Battle of Quiapo and the reestablishment of the fortress of San Felipe de Araucan in 1559.
[6] Alonso de Góngora Marmolejo in his History of All the Things that Have happened in the Kingdom of Chile mentions Colocolo in 1561 as a principal leader in Arauco and is said to be a friend until death to the Spanish.
[10] Claims are Colocolo held the position of "Toqui de la Paz" (Peace Chief) but took over strategic duties when Spanish conquest began, becoming the head of the native Mapuche forces against these invaders.
