The Tres Marias, or Three Marias, off the western coast of Guadalaxara, in the kingdom of Mexico, are in a range stretching from S.E. to N.W. of about forty-five English miles in length. The largest island is the N.W. which appeared a high double land, and above five leagues in length: the middle island about three leagues; and the south-eastermost hardly two leagues. There also are high lands, full of trees; and near the least island there are two or three small broken white islets, one of which was so like a ship under sail, that we gave the signal for a chase. The S.E. end of the island is in lat. 21° 10' N. long. 105° 56' W. and the N.W. point of the N. island is in lat. 21° 40' N. long. 106° 26' W. the distance from each being about two marine leagues. These islands have abundance of parrots of different sorts, with pigeons and other land-birds, of which we killed great numbers. There were also many excellent hares, but much smaller than ours. We saw likewise abundance of guanas, and some racoons, which barked and snarled at us like dogs, but were easily beaten off with sticks. The water is more worthy of remark than any other thing we saw here, as we only found two good springs, which ran in large streams; the others being bitter and disagreeable, proceeding, as I suppose, from being impregnated by shrubs or roots growing in the water, or from some mineral.

The turtle we found here are of a different sort from any I had ever seen, though very good. Though it is ordinarily believed that there are only three sorts of sea-turtles, yet we have seen six or seven sorts at different times, and our people have eaten of them all, except the very large whooping or loggerhead kind, which are found in great plenty in Brazil, some of them above 500 pounds weight. We did not eat of these, because at that time our provisions were plentiful. At the Gallapagos, both males and females were observed to come on shore only in the day time, quite different from what I had heard of them at other places; whereas all we caught here were by turning them over in the night, when the females come on shore to lay their eggs and bury them in the dry sand. One of these whom we caught had 800 eggs in her belly, 150 of which were skinned over and ready for being extruded at once. Some authors alledge that these eggs are six weeks in hatching, which I can hardly credit, as the sun makes the sand in which they are deposited excessively hot, and they are only covered by a very thin film or skin, instead of a shell. In order to ascertain this point, I made some of our men ashore watch one carefully, and mark the place and time of laying her eggs. In less than twelve hours they found the eggs addled, and in about twelve hours more they had young ones completely formed and alive. Had we remained some time longer, I might have thoroughly satisfied myself and others, respecting the quick production of tortoises; for I am apt to credit the report of several of our men, who asserted that having found eggs in the sand, and looked for them three days afterwards in the same place, they then found nothing but films; which shews that the young ones are hatched in that time. They assured me also that they had seen the young brood run out of the sand every day, making directly in great numbers for the sea.

There were few fish about the shores of this island, these being of the ordinary sorts usually met with in these seas; but the abundance of turtle at this time amply made up for this defect. The chief officers fed here deliciously, being scarcely ever without hares, turtle-doves, pigeons, and parrots of various colours and sizes, many of which had white or red heads, with tufts of feathers on their crowns. We found good anchorage at this middle island, and gradual soundings from twenty-four to four fathoms close by the shore; and between this and the least or southern island the depth was about the same as where we were, having no shoal between but what was visible, as a rock lay off the S.W. point and a shoal off the N.E. point of the same, with another at a great distance from that point of the least island, but neither were above half a mile from the shore.

Sailing from these islands, we saw land on the 1st November, which proved to be the point of California, or that headland called Cape St Ducas. It was now necessary to put in execution the rules we had formerly laid down for cruizing, as also to settle our regulations about plunder. Accordingly, my station was to be the outermost in the Duke, the Duchess in the middle, and the Marquis nearest the shore; the nearest ship to be at the least six leagues, and nine at the most from shore, and the bark to ply between ship and ship, carrying advice. By this means we could spread out fifteen leagues, and might see any thing that passed in the day within twenty leagues of the shore; and to prevent any ships passing in the night, we were to ply to windward all day, and to drive to leeward all night. On the 5th November, the Duchess went nearest shore, and the Marquis took the middle station. We were much encouraged by considering that in this very place, and about the same time of the year, Sir Thomas Candish took the Manilla ship.

On the 16th we sent our bark to look for fresh water on the main, and next morning she returned to us, reporting that they had seen wild Indians, who paddled to them on bark-logs. These Indians were fearful of coming near our people at first, but were soon prevailed upon to accept a knife or two and some baize, for which they gave in return two bladders of water, two live foxes, and a deer skin. Till now, we thought that the Spaniards had missionaries among these people, but finding them quite naked, with no appearance of any European commodities, nor a single word of the Spanish language, we concluded that they were quite savage, and we dispatched the bark and a boat a second time, in hopes of procuring some refreshments, with some trifles to distribute among the natives. On the 19th our men returned, having become very familiar with the Californians, who were the poorest wretches that could be imagined, and had no manner of refreshments whatever to afford us. They brought off some Indian knives made of sharks teeth, and a few other curiosities, which I preserved to shew what shifts may be made. It was now the 9th of December, near a month after the time when the Manilla ships generally fall in with this coast, and we were much embarrassed by the impossibility of procuring any intelligence respecting them. On examining our provisions, we found only bread on board for seventy days, even at our present short allowance, and it would require not less than fifty days for our run across the Pacific to Guam, one of the Ladrones; wherefore we resolved to continue our cruize here no longer than other eight days. Being in want of water also, it was agreed upon that the Marquis should go first into a harbour for that necessary article, while the Duke and Duchess continued on the look-out, and then these other ships to do the same in succession.

On the 21st December, while bearing up for the port in which was the Marquis, the man at the mast-head, about nine in the morning, gave notice that he saw a sail besides the Duchess and bark, seeming about seven leagues from us. We immediately hoisted our ensign, and bore for the strange sail, as did the Duchess; and as it fell calm, I sent the pinnace to endeavour to make out what she was. All the rest of the day we had very little wind, so that we made hardly any way, and as our boat did not return we remained in much anxiety, not knowing whether the ship in sight were our consort the Marquis, or the Manilla ship. In this uncertainty, I sent Mr Fry in our yawl to the Duchess, to endeavour to learn what this ship was, and as soon as the yawl was gone I hoisted French colours and fired a gun, which the stranger answered, and in some measure cleared our doubts. Mr Fry soon returned, bringing the joyful news that the ship in sight really was the Manilla galleon for which we had waited so long, and of which we were now almost in despair of meeting. This revived our courage, and every one actively prepared for the engagement; all our melancholy reflections on the shortness of our provisions for the run to Guam being now dispelled, and nothing now occupied our thoughts but of our being masters of the mighty treasure supposed to be on board this ship, while every moment seemed an hour till we could get up with her. We gave orders for the two pinnaces to keep with her all night, shewing false fires from time to time, that we might know whereabout they and the chase were; and it was agreed, if the Duke and Duchess could get up with her together, that we should board her at once. Before night we had made a clear ship, and had every thing in readiness for action at day-light; and all night long we kept a sharp look-out for the boats false fires, which we frequently saw and answered.

At day-break of the 22d December, 1709, we saw the chase about a league from us on our weather bow, the Duchess being a-head of her to leeward about half a league. About six a.m. our boat came aboard, having kept very near the chase all night without receiving any damage, and told us that the Duchess passed the chase in the night, at which time the chase fired two shots at her, which were not returned. Having no wind, we got out eight sweeps, with which we rowed for near an hour, when there sprung up a small breeze. I ordered a large kettle of chocolate to be prepared for the ship's company, having no spirituous liquor to give them, and then went to prayers; but were disturbed before these were finished, by the enemy firing at us. To deter as from attempting to board, they had barrels hung at their yard arms, which resembled barrels of powder. About eight a.m. we began to engage by ourselves, for the Duchess being still at leeward, had not been able to get up, as there was very little wind. At first the enemy fired at us with their stern-chase guns, which we returned with those on our bows, till at length we got close on board each other, when we gave her several broadsides, plying our small arms very briskly; which last the enemy returned as thick for a time, but did not fire their great guns half so fast as we. After some time, we shot a little a-head, laying the enemy athwart hawse close aboard, and plied her so warmly that she soon lowered her colours two-thirds down. By this time the Duchess had got up, and fired about five guns with a volley of small arms; but as the enemy had submitted she made no return.

We now sent our pinnace on board the prize, and brought away the captain and other officers; from whom we learnt that a larger ship had come from Manilla along with them, having forty-six brass guns and as many swivels, but they had parted company with her about three months before, and supposed she had got to Acapulco by this time, as she sailed better than this ship. Our prize had the following high-sounding name Nostra Senoria de la Incarnacion Disenganio, commanded by the Chevalier Jean Pichberty, a Frenchman. She had twenty guns and twenty pattereroes, with 193 men, of whom nine were killed, ten wounded, and several sore scorched with gun-powder. We engaged her three glasses, in which time only I and another were wounded. I was shot through the left cheek, the bullet carrying away great part of my upper jaw and several of my teeth, part of which dropt on the deck, where I fell. The other was William Powell, an Irish landman, who was slightly wounded in the buttock. After my wound, I was forced to write my orders, both to prevent the loss of blood, and because speaking gave me great pain. We received little damage in our rigging during the engagement, except that a shot disabled our mizen-mast. On the 23d, after we had put our ship to rights, we stood in for the harbour where the Marquis was, distant about four leagues to the N.E. sending our surgeons on board the prize to dress her wounded men. We same to anchor in the harbour about four p.m. where we received the compliments of all on board the Marquis on our sudden and almost unlooked-for success, which gave us all much satisfaction. We found that ship in good condition and ready to sail, and all on board her in high spirits, eager for action. At eight the same evening we held a consultation on two important points: first, what we should do with our hostages; and, secondly, how we should act in regard to the other Manilla ship, which we still thought there was a strong probability of our taking, if we could remain here a little longer. As the hostages from Guayaquil, and the Chevalier Pichberty, brother to the famous Monsieur du Cass, appeared to be men of strict honour, we thought it was best to make the best terms we possibly could with them, and then set them at liberty. We had more difficulty in settling the other point in discussion, as to the mode of attacking the other Manilla ship. I was desirous of going out along with the Marquis on that service; but as some reflections had been cast on the Duchess for not engaging our late prize so soon as it was thought she might have done, Captain Courtney was absolutely bent on going out with his own ship and the Marquis, and having a majority in the committee, my proposal was overruled, and we in the Duke were reluctantly constrained to remain in harbour. It was agreed, however, that we should put ten of our best hands on board the Duchess, the better to enable her to engage the great Manilla ship, if she were fallen in with; and she and the Marquis sailed on Christmas-day. As soon as they were gone, we put part of the goods from our bark into the prize, in order to send away our prisoners in the bark; and as there were still due 4000 dollars of the Guayaquil ransom, we agreed to sell them the bark and her remaining cargo for 2000 dollars, taking the Chevalier de Pichberty's bill for 6000 dollars, payable in London, which he readily gave us, together with an acknowledgment under his hand that we had given him a good bargain. This matter being settled, we had only to look to our own safety while our consorts were out on their cruize for the Manilla ship. We posted two centinels on a hill, whence they had a clear view of the sea, with instructions to give us notice by a signal whenever they saw three ships in the offing, that we might have time to secure our prisoners, and to get out to the assistance of our consorts, as we expected they might have hot work, this other Manilla ship being much stronger and better manned than the one we had taken, and better provided in all respects.

On the afternoon of the 26th, our sentries made the appointed signal of seeing three ships; on which we immediately put all our prisoners into the bark, from which we removed her sails, and took away all our men, except two lieutenants and twenty-two men, whom we left to look after our prize and the prisoners. As the prisoners, though 170 in number, were secured in the bark, without sails, arms, rudder, or boat, and moored near a mile distant from our prize, there were more than sufficient for guarding them and giving them provisions and drink during our absence. This being arranged, we immediately weighed and stood to sea, in order to assist our consorts in attacking the great ship. Captain Dover thought proper to go on board the prize, instead of one of our lieutenants, whom he sent to me. I was still in a very weak condition, my head and throat being very much swelled, so that I spoke with great pain, and not loud enough to be heard at any distance; insomuch that all the chief officers and our surgeons wished me to remain in the prize, but I would not consent. We got under sail about seven p.m. and saw lights several times in the night, which we supposed to be false fires in the boats of our consorts. In the morning of the 27th at day-break, we saw three sail to windward, but so far distant that it was nine o'clock before we could make out which were our consorts and which the chase. At this time we could see the Duchess and the chase near together, and the Marquis standing to them with all the sail she could carry. We also made all the sail we could, but being three or four leagues to leeward, and having a very scant wind, we made little way. At noon they bore S.E. from us, being still three leagues right to windward. In the afternoon we observed the Marquis get up with the chase, and engage her pretty briskly; but soon fell to leeward out of cannon shot, where she lay a considerable time, which made us conclude that she was somehow disabled.

I sent away my pinnace well manned, with orders to dog the chase all night, making signals with false fires that she might not escape us; but before our boat could get up to them, the Marquis made sail again towards the chase, and went to it again briskly for more than four glasses. At this time we saw the Duchess steer ahead to windward, clear of the enemy, as I supposed to stop her leaks or repair her rigging. Meanwhile the Marquis kept the enemy in play, till the Duchess again bore down, when each fired a broadside or two, and left off because it grew dark. They then bore south of us in the Duke, which was right to windward, distant about two leagues; and about midnight our boat came to us, having made false fires, which we answered. Our people had been on board both the Duchess and Marquis, the former of which had her foremast much disabled, the ring of an anchor shot away, one man killed and several wounded, having also received several shots in her upper works and one in her powder-room, but all stopt. The Duchess had engaged the enemy by herself the night before, which was what we took to be false fires, being too distant to hear the guns. At that time they could perceive the enemy to be in great disorder, her guns not being all mounted, and neither her nettings nor close quarters in order; so that, if it had been my good fortune in the Duke to have gone with the Duchess, we all believed we might then have carried this great ship by boarding; or, if the Duchess had taken most of the men out of the Marquis, which did not sail well enough to come up to her assistance in time, she alone might have taken her by boarding at once, before the Spaniards had experienced our strength, and become afterwards so well provided as encouraged them to be driving, giving us every opportunity to board them if we pleased.
