The outbreaks of revolution began and in Arequipa, Castilla took over the insurrection. He arrived on 13 February to the acclamation of the people. Echenique sent his troops to the south, but Castilla defended the city with fewer men. At the end of March, Castilla moved to
Cusco. On 14 April he received the announcement that the Revolutionary Junta of Arequipa has proclaimed him Provisional President. With a formed army he arrived in Andahuaylas on 8 June, and on the 23rd he met in Bombón with General Del Castillo's division. On 3 July he occupied Huamanga, escorted by the famous "Morochucos". Despite the fact that the country now had two presidents, Castilla issued on 5 July the historic decree abolishing the indigenous tribute, which gave his revolution a social character. Domingo Elías returned to the country, prompting the government to send troops against him and to attempt an unsuccessful defense of the plaza of
Arica. On the other hand, Vivanco, since his exile in Chile, returned, but did not participate as he felt "marginalized" by Castilla. From
Huamanga, the latter traced his final strategy. Echenique advanced towards Jauja and thought to have attacked Castilla in Huancayo, but he could not defeat General Izcuchaca's troops in Huancavelica. So he occupied the Mantaro Valley, while Castilla campsed in a poor region and decides to go to the heights to threaten
Lima and attempt force Echenique's return. His plan worked. On 3 December in Huancayo, Castilla issued another decree abolishing slavery. On 5 January 1855, at the La Palma hacienda, Castilla's troops defeated those of Echenique, who had to be sheltered in the house of the British charge d'affaires, Sullivan. The Government Palace, the President's house and his wife's
quinta were looted, as well as that of his relatives and his closest collaborators. Echenique then went into exile. ==Aftermath==
