upon him at night with 700 light troops, but was beaten off with the loss of two guns; and the next day Las Heras occupied Concepcion.
Concepcion lies on the northern bank of the Bio-Bio, at the head of the peninsula of Talcahuano, and about five miles distant from the fortified town of the same name. Las Heras was thus in a critical position; he dare not retreat, and his force was insufficient to attack Ordoñez in his entrenchments. He built a small fort on the Gavilán Hill, to the south-west of Concepcion, and waited for O'Higgins. On the 1st May four Spanish vessels anchored in the Bay of Talcahuano, bringing the 1,600 fugitives from Chacabuco, who had been sent back from Peru to reinforce the garrison, and Ordoñez thought himself strong enough to resume the offensive. On the night of the 4th he sallied out with 700 men and four guns to attack the left flank of the position held by Las Heras, while Colonel Morgado, with 400 men and two guns attacked on the right, and a small force in boats rowed up the Bio-Bio to menace the city from the river. The action commenced at daybreak and was hotly contested for three hours, until Freyre, who commanded on the right of the position, having routed Morgado and captured his two guns, came to the assistance of Las Heras, and Ordoñez was compelled to retreat, hotly pursued by the grenadiers under Medina, who captured one of his guns.

Ordoñez having command of the sea and the Bio-Bio, had easy communication with the ports of Arauco, which both furnished supplies and harassed the left flank of the Patriots. Freyre, with a
