The new Triumvirate lost no time in setting about their appointed task; the Constituent Assembly was speedily convened, the victorious army of Tucuman was strongly reinforced, and another army was despatched to besiege Monte Video.

Thus in the space of seven months from the arrival of San Martin in Buenos Ayres the aspect of affairs was completely changed. Government was consolidated, its policy defined, public spirit was aroused, and the revolution, with two armies, boldly displayed the flag of independence. But the military situation was precarious, everything depended upon the result of a battle.

Monte Video was a fortress of the second class, was defended by 335 guns, of which 175 were in battery, was garrisoned by more than 3,000 troops and by 2,000 militia, and was further protected by a squadron of 14 ships of war, mounting 210 guns, and by a flotilla, while the United Provinces had not even a gunboat. Here was the centre of reaction and the natural base for any expedition from the Peninsula, while the state of relations with Brazil increased the danger from this quarter.

The Royalist army, beaten at Tucuman, had been strongly reinforced, and lay entrenched at Salta, waiting the arrival of another army from Upper Peru.

Government summoned a council of military chiefs—of whom San Martin was one—and of influential citizens, to aid the Cabildo in devising measures to meet these threatening dangers. It was decided that Monte Video must be taken at any cost, and that Belgrano should be instructed to drive the enemy from Salta, in order to open the road to the centre of the Spanish power at Lima.

CHAPTER IV.
SAN LORENZO.
1813—1814.

ON the 31st December, 1812, the vanguard of the army sent against Monte Video, under the command of Colonel Rondeau, completely defeated a strong sortie of the garrison and laid siege to the city.

On the 31st January, 1813, the general Constituent Assembly met in Buenos Ayres. The majority were members of the Lautaro Lodge, so there was no longer that anarchy of opinion which had neutralized the former Assemblies. For the moment it fulfilled popular aspirations; the nominal sovereignty of the King of Spain was eclipsed, his name disappeared for ever from public documents, the escutcheons of Spain were torn down, titles of nobility, the Inquisition, and judicial torture were abolished. The effigy of former monarchs was substituted on coins by the seal of the United Provinces—a sun with rays and a Phrygian cap, within a wreath of laurel. The colours of the Spanish flag were replaced by the blue and white of the Patriot cockade, and the last link with the mother country was broken by declaring the supremacy of the National Courts of Law. Everything was reformed, even to the prayers of the priests and the songs of the people, who now in inspired verse saluted,

“A new and glorious Nation,
With a conquered lion at her feet.”[9]
