Naturally, Captain Vavassour was not the sort of man to see a possible rich prize riding at anchor in the enemy's waters without making a determined attempt to secure possession of her; we therefore stood boldly in after the Indiaman until we arrived within half a mile of the entrance of the bay--at that point about two miles across--when two batteries of six guns each, built upon opposite headlands forming the entrance to the bay, opened fire upon us, and with such effect that within five minutes we had been hulled seven times, and had lost two men killed and five wounded.  This afforded the skipper all the information that he just then required, namely, the fact that batteries existed, and also the exact position and strength of them--it now appearing that they were armed with 32-pounders.  We therefore hove about and got out of range again as quickly as possible; for, as the Captain said, it was no good returning the fire of earthwork batteries; we might have plumped into them every shot we had on board without doing them a farthing's-worth of damage, while, had we attempted to force a passage into the bay with the frigate, they might easily have sunk us.
