Killed by Chinese pirates.

Killed at sea." There were more of these gruesome items--so many of them that it appears as though no more than a handful of this stalwart crew survived the Massachusetts by a dozen years.

Incredible as it sounds, Captain Delano's roster accounted for fifty of them as dead while he was still in the prime of life, and most of them had been snuffed out by violence.
As for his own career, it was overcast by no such unlucky star, and he passed unscathed through all the hazards and vicissitudes that could be encountered in that rugged and heroic era of endeavor.

Set adrift in Canton when the Massachusetts was sold, he promptly turned his hand to repairing a large Danish ship which had been wrecked by storm, and he virtually rebuilt her to the great satisfaction of the owners.
Thence, with money in his pocket, young Delano went to Macao, where he fell in with Commodore John McClure of the English Navy, who was in command of an expedition setting out to explore a part of the South Seas, including the Pelew Islands, New Guinea, New Holland, and the Spice Islands.

The Englishman liked this resourceful Yankee seaman and did him the honor to say, recalls Delano, "that he considered I should be a very useful man to him as a seaman, an officer, or a shipbuilder; and if it was agreeable to me to go on board the Panther with him, I should receive the some pay and emoluments with his lieutenants and astronomers." A signal honor it was at a time when no love was lost between British and American seafarers who had so recently fought each other afloat.
And so Amasa Delano embarked as a lieutenant of the Bombay Marine, to explore tropic harbors and goons until then unmapped and to parley with dusky kings.
