Monday, December 17th, 1821, commenced with fine breezes from the eastward. At daybreak saw some of the islands northward of Cape Cruz, called Keys--stood along northwest; every thing now seemed favorable for a happy termination of our voyage. At 3 o'clock, P.M., saw a sail coming round one of the Keys, into a channel called Boca de Cavolone by the chart, nearly in latitude 20° 55' north, longitude 79° 55' west, she made directly for us with all sails set, sweeps on both sides (the wind being light) and was soon near enough for us to discover about forty men on her deck, armed with muskets, blunderbusses, cutlasses, long knives, dirks, &c., two carronades, one a twelve, the other a six pounder; she was a schooner, wearing the Patriot flag (blue, white and blue) of the Republic of Mexico. I thought it not prudent to resist them, should they be pirates, with a crew of seven men, and only five muskets; accordingly ordered the arms and ammunition to be immediately stowed away in as secret a place as possible, and suffer her to speak us, hoping and believing that a republican flag indicated both honor and friendship from those who wore it, and which we might expect even from Spaniards. But how great was my astonishment, when the schooner having approached very near us, hailed in English, and ordered me to heave my boat out immediately and come on board of her with my papers.--Accordingly my boat was hove out, but filled before I could get into her.--I was then ordered to tack ship and lay by for the pirates' boat to board me; which was done by Bolidar, their first lieutenant, with six or eight Spaniards armed with as many of the before mentioned weapons as they could well sling about their bodies. They drove me into the boat, and two of them rowed me to their privateer (as they called their vessel), where I shook hands with their commander, Captain Jonnia, a Spaniard, who before looking at my papers, ordered Bolidar, his lieutenant, to follow the Mexican in, back of the Key they had left, which was done. At 6 o'clock, P.M., the Exertion was anchored in eleven feet water, near this vessel, and an island, which they called Twelve League Key (called by the chart Key Largo), about thirty or thirty-five leagues from Trinidad. After this strange conduct they began examining my papers by a Scotchman who went by the name of Nickola, their sailing master.--He spoke good English, had a countenance rather pleasing, although his beard and mustachios had a frightful appearance--his face, apparently full of anxiety, indicated something in my favor; he gave me my papers, saying "take good care of them, for I am afraid you have fallen into bad hands." The pirates' boat was then sent to the Exertion with more men and arms; a part of them left on board her; the rest returning with three of my crew to their vessel; viz., Thomas Young, Thomas Goodall, and George Reed--they treated them with something to drink, and offered
