Devout Puritan Slave Traders
“The first American slave ship shown in the records was the Rainbow which sailed from Boston for Africa in 1645. On the Guinea Coast her captain found a shortage of slaves at the trading posts. With the help of the captains of several English ships also waiting in vain for slaves, an expedition was organized to go into the interior. The slave hunters took along a “murderer,” a light cannon also called a swivel gun as it was mounted to be easily swung in any direction. With it they attacked a native village, killed many of its people and managed to capture a few slaves.
The Rainbow’s captain got only two for his share, but with his meager cargo he sailed back to Boston since there was a good market for slaves there. In Boston his troubles continued. The ship’s owner learned that the raid on the African village had taken place on a Sunday.
In the eyes of the stern Puritans this was a shocking crime and the captain was arrested, tried for murder, man-stealing and Sabbath-breaking. He was acquitted however, since the Massachusetts Bay court decided it had no power to punish a man for something that happened outside the colony. The two slaves were seized by the government and sent home to Africa, so this first American slaving voyage on record was a dismal failure.”
