On the 4th July, the armistice having run out, La Serna publicly announced his determination to abandon Lima, and delegated the supreme authority to the Marquis of Montemira. He left a garrison of 2,000 men in the fortifications of Callao, 1,000 sick in the hospitals, and, on the morning of the 6th, marched off with barely 2,000 men, by the valley of Cañete.

The city was panic struck. The leading Spaniards fled with their families to Callao. The women rushed to the monasteries. San Martin hastened to reassure the people by a letter to the Archbishop, and, faithful to his declared policy, made no attempt to occupy the city. A deputation of the inhabitants waited upon him, asking his protection: whereupon he ordered the guerillas, of whom they were most afraid, to retire from the neighbourhood, and surrounded the city with a cordon of regular troops, placing them under the orders of the civil governor. Still the citizens could not believe that he was acting in good faith till an order from the Governor to a regiment of cavalry, which had encamped a mile and a half from the city, to retire to a greater distance, was at once obeyed, when confidence was restored, and, at the invitation of the authorities, at sundown on the 9th, a division of the army entered the city amid the shouts of the populace.

The next day, after sundown, San Martin, accompanied only by an aide-de-camp, rode quietly through the streets of the city to the palace of the Viceroys, where the citizens thronged to give him welcome, and the members of the Cabildo, hurriedly convened, presented him with an address. He soon wearied of their enthusiastic protestations of regard, and, remounting his horse at half past ten, he rode out to the village of Mirones, half-way to Callao, where he had established the headquarters of his army, as a preliminary step to laying siege to the fortress.

On the 11th he issued various proclamations to the citizens, and the royal arms were torn down from over the doors of the public offices, the escutcheon of Peru being put in their place, with the inscription Lima Independiente.

San Martin also issued a proclamation to the inhabitants of the liberated departments, calling them to arms, and promising, with their assistance, to finish the campaign in forty days. But he took no active measures in furtherance of this project. Apparently he attached too much importance to the possession of Lima, for, with the exception of Trujillo, the country had as yet made no effort to second him, and remained passively watching the course of events.

The Viceroy, with his dispirited army, was allowed to retreat almost unmolested, though his loss by desertion was very great. Canterac was already securely established in the Highlands. San Martin here repeated the mistake he was guilty of after Chacabuco. Again he showed want of energy in following up a victory. He attached too much importance to the success which had so far attended his political combinations.

CHAPTER XXX.
THE SECOND CAMPAIGN IN THE HIGHLANDS.
1821.

WHEN Arenales rejoined the main army at Huara, and Ricafort descended by the mountain passes to Lima, Aldao and his Indian hordes were left in possession of the greater part of the Highlands, opposed only by a division under Carratala, who held Huancavelica and Huamanga. Aldao had given his Indians some sort of organization, styling the cavalry “The Mounted Grenadiers of Peru,” and the infantry, “The Loyalists of Peru,” under which names they figured as the two first Peruvian regiments on the muster roll of the liberating army. San Martin had small faith in such troops, nevertheless, as a step towards forming a native army, he appointed Colonel Gamarra, a Peruvian, Commandant-General of the Highlands, and in February sent him, with a number of officers of all ranks, to take the command.

About the same time Ricafort returned to Huancavelica, and one of the first measures of La Serna after he became Viceroy, was to send Valdés with 1,200 men to support him. The united forces of the Royalists numbered 2,500 men, but on advancing against Aldao, they found that the suspension bridges over the Rio Grande had been cut by the Indians. Nevertheless they found a place at which they could ford the stream and easily put to flight the raw levies opposed to them.

Before they could reach Gamarra, he had retreated from Jauja and Pasco with 600 of Aldao’s men, by the pass of Oyuna, where his men dispersed. Carratala remained watching the pass, while Valdés and Ricafort returned by Canta to Lima; but were so harassed on the march by Vidal’s guerillas, that an entire company of light infantry were taken prisoners, and Ricafort, badly wounded, was carried into Lima on a stretcher.
