FROM BUENOS AYRES.

The brig Sarah, Ashton, from Rio Grande, which place she left on the 11th of June, arrived here this morning.

The Buenos Ayrean army, consisting of 12 or 13,000 men, under the command of General Alvear,-had fortified themselves at Bejar, about 40 leagues from Rio Grande. Their advance guard of 2000 cavalry was under the command of Gen. Lavelega. On the 1st of June a detachment of about 300 came within twenty miles of Rio Grande, and carried off a large quantity of cattle, after which they fell back to the main army. Since the action of the 20th February, in which the Brazilian forces were defeated, they have not been able to bring any collected force into the field, and no movement of any consequence had taken place. The Buenos Ayrean troops behaved well to the inhabitants, and were joined by some of them. On the 20th May a party of the former, in number about 150, were surprised in a small village, at a distance from the army, by about 400 Brazilian troops; and after an obstinate resistance, during which the Brazilians set fire to the houses in which they were surprised, ninety-five surrendered or were taken prisoners. The remainder refused to yield, and were burnt in the houses. No business was doing. Flour was at 7 mil reas, and the market well supplied.

No immediate attack was apprehended, and the place was well fortified. Capt. Ashford reports, that Com. Brown had captured, on the 4th of June, off Rio Negro, two ships from the Brazilians, one of 32 guns, and the other a corvette.
