CHAPTER XXXV.
THE DISASTER AT ICA.
1821—1822.
After the return of the expedition from Callao, La Serna removed his head-quarters to Cuzco, leaving the bulk of the army behind him in the valley of Jauja, under Canterac. He strengthened the garrisons of Puno, Arequipa, and Tacna, and entrusted the defence of the southern coast to the army of Upper Peru.
Canterac detached two light columns under Loriga against Pasco, where the insurrection had still a footing under Otero, who had 200 regulars with him and 5,000 Indians. On the approach of Loriga, Otero marched out to attack him, and fell upon him suddenly, in the early morning of the 7th December, at the village of El Cerro, where the Royalists had halted to collect supplies. In the confusion a part of the ammunition blew up, and the troops in the darkness were seized with panic, but Loriga succeeded in rallying them, occupied the church and some neighbouring houses, and waited for daylight, when he in his turn attacked the Patriots, and completely routed them, killing 700 Indians.
In Upper Peru, Lanza, the guerilla chief, maintained himself in the mountains between Cochabamba and La Paz.
In Potosí a mutiny broke out among the troops, which was quelled by General Maroto.
