On the night or morning of the 19th March, 1823, an attempt was made at another revolution, upon the plea that the religion of the country was in danger. Gregorio Taglé, a lawyer, and a man of some talent, was the chief of this conspiracy: he had been formerly one of the state ministers; and, after its failure, he escaped to Colonia. The disturbance began by some hundreds of Gauchos from the country galloping into the town, shouting "_Viva la religion!_" &c. &c. They overpowered the guard at the Cabildo, released the prisoners, and began to toll the bell; and at that hour (two o'clock in the morning) it did certainly frighten the town "from its strict propriety." In the Plaza they were received by a discharge of musquetry from a few troops, who had advanced out of the Fort, and who, after killing and wounding several, put the rest to the rout. Garcia, a Colonel, implicated in the plot, was shot a few days afterwards: he met his fate with firmness. This execution was followed by two more, those of Colonel Peralto and Urien. The latter had been an officer both in the Buenos-Ayrean and Peruvian services, and now suffered for a participation in the conspiracy, and a murder committed some years ago. He was in confinement at the Cabildo, awaiting his sentence for the latter offence, and being a relation of Mr. Rivadavia, interest was making to save him, when the conspirators released him. Strict search was made for the escaped criminal; and in a few days, he surrendered himself, upon a promise of pardon on condition of his making discoveries of those concerned in the late conspiracy. Several were arrested upon his depositions; amongst them, an English shopkeeper named Hargreaves, whom he accused of selling fire-arms to the rioters at one and two in the morning of the 19th March. An examination proved that all the accusations were false: the accused were released, and Urien desired to prepare for death. Urien was well known in the coffee-houses of Buenos Ayres; he was much in debt, and some of his creditors were Englishmen. The murder of which he was convicted, was committed in conjunction with a female, the wife of the murdered man, and the body had been cut in pieces, and buried at different times. Since the murder, he had been in Peru, and had also lived in Buenos Ayres, unsuspicious of discovery. Having a fine person and countenance, he was a favourite with the ladies, and a complete "man upon town."
