While awaiting the arrival of Simón Bolívar's army, groups of patriots gathered clandestinely in the Junín region, ready to confront the troops loyal to the Spanish crown. They were led by the guerrilla fighter José Fresco, renowned for his bravery by General José de San Martín. He was accompanied by Rosita, the peasant Ninavilca, and Friar Bruno Terreros. These warriors would join the fight, reinforcing the regular armies. They fought successfully in the battles of Junín and Ayacucho.
