"I told you I would be with you when the fighting came," said the boy, with a bright smile. "Before day I was up and saddled my pony and came away. I have watched them all the morning, and I knew you could not be far off."

"But they? Where are they?"

"They have gone, do not I tell you? There where those quintas hide the river, the Paso Chico. They have crossed by the pass, and have marched up the road straight away for town."

"There, Evaristo, over there," said Marcelino, pointing towards the hollow where the army of Buenos Aires was waiting, drawn up in battle-array, for the foe who had escaped them; "gallop as hard as you can to General Liniers and tell him that. Tell him that I have gone in pursuit."

As Evaristo galloped off, Marcelino put spurs to his horse, and, rejoining his negroes, urged them on; but, rapidly as they marched, the British riflemen, who had nothing more than their rifles and cartridge-boxes to carry, out-paced them, and had crossed the pass ere Marcelino and his negroes reached the river.

Evaristo was not the first to announce to General Liniers the evasion of the English vanguard. Colonel Lopez had also watched them all the morning, hovering on their flanks and rear, but not venturing to molest them. When he saw them march from their second position straight for the Paso Chico, he sent off an officer at once to the general with the intelligence, and putting himself at the head of such of his cavalry as he could collect around him he drew them up across the road leading to the pass. One British regiment deployed, poured in a volley, charged, and drove most of the horsemen pell-mell across the pass to the other side, dispersing the rest in all directions. Again collecting some of his scattered troops, Colonel Lopez endeavoured to cut off the retreat of the detachment which had remained on the lomada. But the ground favoured the light-armed infantry. Instead of following in the track of the main body, they made at once for a quinta which lay between them and the river, and bursting through the fences, which were impracticable for cavalry, reached the pass, and crossed without the loss of one man. The colonel then led his troopers to the road at a gallop, but on reaching the river was met by a volley of grape from two field-pieces in position on the far bank. Many of his men fell. He drew back to the shelter of the poplars which formed the quinta fence, and awaited the arrival of his nephew.

Marcelino, dismounting when he reached the quinta, led his men on foot to the edge of the river, just in time to witness the repulse of the cavalry. The owner of the quinta had a boat moored to a post about a square down the stream, hidden from sight of the pass by a bend in the river and the trees of another quinta on the left bank. Enjoining the strictest silence, Marcelino marched his men with trailed arms through the quinta to beyond the bend, rapidly passed them across the river, and took possession of the other quinta without being perceived by the enemy, who first knew of his whereabouts as from the shelter of the trees he opened a heavy fire upon the artillerymen and the light infantry who had halted close at hand. Colonel Lopez, who had been informed by him of his intention, and who had meantime been reinforced by several squads of cavalry, once more emerged into the main road, and, at the head of a yelling mob of horsemen, dashed through the pass. For a moment the capture of the guns appeared inevitable; the artillerymen defended themselves desperately, but were completely surrounded by the furious horsemen.

Colonel Lopez, however, by his eagerness to capture the guns, blocked up the head of the pass, and prevented the passage of half of his troops, and the riflemen, who were screened by the horsemen from the fire of the negro corps, rushed upon the disordered mass with levelled bayonets, forced many of them into the river, and drove the rest back upon the quinta. The negroes, who were advancing from the shelter of the trees to the assistance of the horsemen, were thrown into great disorder by the fugitives, and before Marcelino and Asneiros could reform their broken ranks and draw them clear they were attacked in flank by an entire regiment of light infantry, which was sent at the double by General Gower to the support of the rifles.

The bulk of the British vanguard had halted about a quarter of a mile from the pass to rest the troops after their rapid march from the lomada. General Gower had not perceived the passage of the river by the negroes, and was taken by surprise at the sudden fire opened upon his two guns from the quinta. The whole force was immediately under arms, and one regiment, driving Colonel Lopez and his scattered horsemen before them, charged upon the right flank of the "Morenos" at the same moment that the guns opened fire upon them from the river-side.

"To the quinta, muchachos!" shouted Marcelino.
