Title:
Marshall_Islands

Context:
A number of vessels visiting the islands were attacked and their crews killed. In 1834, Captain DonSette and his crew were killed. Similarly, in 1845 the schooner Naiad punished a native for stealing with such violence that the natives attacked the ship. Later that year a whaler's boat crew were killed. In 1852 the San Francisco-based ships Glencoe and Sea Nymph were attacked and everyone aboard except for one crew member were killed. The violence was usually attributed as a response to the ill treatment of the natives in response to petty theft, which was a common practice. In 1857, two missionaries successfully settled on Ebon, living among the natives through at least 1870.:3
