A fresh incident arose to interrupt the succour carried to them, and to redouble the terror and confusion. Captain Curtis, a sailor as daring as he was skilful, suddenly advanced with his gun-boats, which had been constructed to confront those of the Spaniards, and each of which carried in front an eighteen or twenty-four pounder. Their fire at water-level rendered them exceedingly formidable; and they were disposed by Captain Curtis so as to take the line of floating batteries in flank.

From that moment the position of the Spaniards became terribly critical. The boats no longer dared to approach them, but were constrained to abandon those enormous machines, so lately the objects of their admiration, to the flames, and their companions in arms to the mercy of an enraged enemy. Several of them were seen to founder. Others only escaped by forced rowing. A few sought shelter by the land during the night; but, on the appearance of daylight, they were easily captured by the English.
