On 1 January 1824 Bolívar fell terribly ill in Pativilca. At that time, Félix Álzaga, plenipotentiary minister of Provincias Unidas del Río de la Plata arrived to Lima, requested Peru to adhere to the truce, which was rejected by the Peruvian Congress. Nevertheless, since 4 February 1824 various quarters of Callao mutinied, leading to the whole Argentine infantry of the "Expedición Libertadora", together with some Chilean, Peruvians and Colombians (nearly two thousand men) going over to the royalists, raising the Spanish flag and handing over the fortresses of Callao. The mounted grenadier regiment of the Andes also revolted in Lurin on 14 February: two squadrons went over to the Callao to join the mutiny, but when they noticed that they had joined the royalists, a hundred of them, with their regiment commanders, went to Lima to join the independentists. The unit was then reorganized by General Mariano Necochea. In the midst of these events, the minister of Colombia, Joaquín Mosquera "fearing the ruin of our army" asked Bolivar "and what do you plan to do now?". Bolívar, in a decided manner, answered: "Triumph!".
