Captain Gibson commanded one of these ships, and Avery appears to have been his mate, in the year 1715.  He was a fellow of more cunning than courage, and insinuating himself into the confidence of some of the boldest men in the ship, he represented the immense riches which were to be acquired upon the Spanish coast, and proposed to run off with the ship.  The proposal was scarcely made when it was agreed upon, and put in execution at ten o’clock the following evening.  Captain Gibson was one of those who mightily love their bottle, and spent much of his time on shore; but he remained on board that night, which did not, however, frustrate their design, because he had taken his usual dose, and so went to bed.  The men who were not in the confederacy went also to bed, leaving none upon deck but the conspirators.  At the time agreed upon, the long boat of the other ship came, and Avery hailing her in the usual manner, he was answered by the men in her, “Is your drunken boatswain on board?” which was the watchword agreed between them.  Avery replying in the affirmative, the boat came alongside with sixteen stout fellows, who joined in the adventure.  They next secured the hatches, then softly weighed anchor, and immediately put to sea without bustle or noise.  There were several vessels in the bay, besides a Dutchman of forty guns, the captain of which was offered a considerable reward to go in pursuit of Avery, but he declined.  When the captain awoke, he rang his bell, and Avery and another conspirator going into the cabin, found him yet half asleep.  He inquired, saying, “What is the matter with the ship? does she drive? what weather is it?” supposing that it had been a storm, and that the ship was driven from her anchors.  “No, no,” answered Avery, “we’re at sea, with a fair wind and a good weather.”  “At sea!” said the captain:  “how can that be?” “Come,” answered Avery, “don’t be in a fright, but put on your clothes, and I’ll let you into a secret.  You must know that I am captain of this ship now, and this is my cabin, therefore you must walk out; I am bound to Madagascar, with a design of making my own fortune, and that of all the brave fellows joined with me.”

The captain, having a little recovered his senses, began to understand his meaning.  However, his fright was as great as before, which Avery perceiving, desired him to fear nothing; “for,” said he, “if you have a mind to make one of us, we will receive you; and if you turn sober, and attend to business, perhaps in time I may make you one of my lieutenants; if not, here’s a boat, and you shall be set on shore.”  Gibson accepted of the last proposal; and the whole crew being called up to know who was willing to go on shore with the captain, there were only about five or six who chose to accompany him.
