Moody marooned Cocklyn and 25 others, denying them shares of treasure. Moody's crew, angry over his treatment of Cocklyn, returned the favor by setting Moody and 12 of his supporters adrift in a small boat. The Rising Sun’s crew elected French pirate Olivier Levasseur as captain.

Soon met by Howell Davis near the Sierra Leone River, the group captured a number of vessels in quick succession, including Snelgrave's Bird Galley. The pirates exchanged ships several times, each keeping best of the lot, finally leaving the captured snow Bristol to Snelgrave and his crew. Snelgrave had been fond of Davis, who protected him, but was wary of the cruelty of Cocklyn, having witnessed him caning his own sailors

The three captains eventually quarrelled and went their separate ways. Another source reports that Cocklyn was hanged for piracy.
