And now we prepared to return to Juan Fernandez, and hauled up to the south-west with that view, having but very little wind till the 12th, when, at three in the morning, there sprang up a fresh gale from the west-south-west, and we tacked and stood to the north-west; and at daybreak we were agreeably surprised with the sight of a sail on our weather-bow, between four and five leagues distant. On this we crowded all the sail we could, and stood after her, and soon perceived it not to be the same ship we originally gave chase to. She at first bore down upon us, showing Spanish colours, and making a signal as to her consort; but observing that we did not answer her signal, she instantly luffed close to the wind and stood to the southward. Our people were now all in spirits, and put the ship about with great alacrity; and as the chase appeared to be a large ship, and had mistaken us for her consort, we conceived that she was a man-of-war, and probably one of Pizarro's squadron. This induced the Commodore to order all the officers' cabins to be knocked down and thrown overboard, with several casks of water and provisions which stood between the guns; so that we had soon a clear ship, ready for an engagement. About nine o'clock we had thick, hazy weather, and a shower of rain, during which we lost sight of the chase; and we were apprehensive, if the weather should continue, that by going upon the other tack, or by some other artifice, she might escape us; but it clearing up in less than an hour, we found that we had both weathered and forereached upon her considerably, and now we were near enough discover that she was only a merchantman, without so much as a single tier of guns. About half an hour after twelve, being then within a reasonable distance of her, we fired four shot amongst her rigging, on which they lowered their topsails and bore down to us, but in very great confusion, their top-gallant-sails and stay-sails all fluttering in the wind. This was owing to their having let run their sheets and halyards just as we fired at them, after which not a man amongst them had courage enough to venture aloft (for there the shot had passed but just before) to take them in. As soon as the vessel came within hail of us, the Commodore ordered them to bring to under his lee-quarter, and then hoisted out the boat and sent Mr. Suamarez, his first lieutenant, to take possession of the prize, with directions to send all the prisoners on board the Centurion, but first the officers and passengers. A TERRIFIED CREW.
