action as was needful in the emergency. But as the Indian squadron approached, a breeze suddenly sprang up, and Cortéz, widening his line of battle, bore down upon the frail skiffs, overturning, crushing and sinking them by the first blow of his formidable prows, whilst he fired to the right and left amid the discomfitted flotilla.
