and driven back with heavy loss; but the Royalists pursuing them down the slope were in their turn forced to retire by a withering fire from the Chilian guns, under Borgoño, which had remained on the crest of the Loma Blanca.
San Martin now sent orders to the reserve to advance at once, in support of the left wing, by an oblique movement across the low ground, so as to fall upon the flank of the Spanish infantry. On his way Quintana was joined by three battalions of those that had been driven back, and fell with great impetuosity upon the Royalists, who, however, held their ground most tenaciously. Meantime Freyre, with the Chilian cavalry, had charged and put to flight the Royalist cavalry on the right, and now came back upon the other flank of the Spanish infantry. Alvarado, having rallied his broken division, came to the assistance of Quintana with Borgoño and his eight guns.
Osorio, after sending orders to Rivera to withdraw from his advanced position, fled, leaving Ordoñez in command, who at once commenced to retreat in excellent order upon the farmhouse of Espejo.
At this moment O'Higgins, wounded as he was, appeared upon the field, and, meeting San Martin, greeted him as the saviour of Chile; but it was already five o'clock, and the battle was not yet won. Ordoñez, with heavy loss, had made good his retreat to the farmhouse, where he made the most active preparations for defence.
Las Heras, in pursuit of the left wing, was the first to arrive there, but found several detached corps there before him. He immediately ordered the occupation of the high grounds around it, which commanded the position, but Balcarce coming up ordered an immediate attack by the road. Colonel Thompson, with a battalion of Chilian light infantry, led the assault, but was beaten back with grape and musketry, losing 250 killed, and all his officers wounded. Borgoño and Blanco Encalada from the high ground then opened fire with seventeen guns, and soon drove the enemy from his outer defences into the houses
