On his coming back from thence, by the recommendation of the Duke of Chandois, he was made by the Royal African Company a lieutenant colonel in their service, and an engineer for erecting a fort on the Coast of Africa. He promised himself great advantage and a very honourable support from this employment, but he and the soldiers under his command being very ill used by the person who commanded the ship in which he went over (being denied their proportion of provisions and in all other respects treated with much indignity) it made a great impression on Captain Massey's mind, who could not bear to see numbers of those poor creatures perish, not only without temporal necessities, but wanting also the assistance of a divine in their last moments. For the chaplain of the ship remained behind in the Maderas, on a foresight perhaps, of the miseries he should have suffered in the voyage. In this miserable condition were things when the Captain and his soldiers came into the River Gambia, where the designed fort was to be built. Here the water was so bad that the poor wretches, already in the most dreadful condition, were many of them deprived of life a few days after they were on shore. The Captain was excessively troubled at the sight of their misfortunes and too easily in hopes of relieving them gave way to the persuasion of a captain[29] of a lighter vessel than his own, who arrived in that port, and persuaded him to turn pirate rather than let his men starve. After repeated solicitations, Captain Massey and his men went on board this ship, and having there tolerable good provisions, soon picked up their strength and took some very considerable prizes. At the plundering of these Massey was confused and amazed, not knowing well what to do, for though he was glad to see his men have meat, yet it gave him great trouble when he reflected on the methods by which they acquired it. In this disconsolate state his night was often so troublesome to him as his days, for, as he himself said, he seldom shut his eyes but he dreamt that he was sailing in a ship to the gallows, with several others round him. After a considerable space, the ship putting into the island of Jamaica for necessary supply of water and provision, he made his escape to the Governor, and gave him such information that he took several vessels thereby; but not being easy there, he desired leave of Sir Nicholas Laws to return home. Sir Nicholas gave him letters of recommendation, but notwithstanding those, he no sooner returned in England but he was apprehended and committed for piracy. Soon after which he was bailed; but the persons who became security growing uneasy, he surrendered in their discharge, soon after which he was tried, convicted and condemned.
