Serpent

The Serpent was a pirate gunboat briefly captained by the French pirate Alonzo Batilia during June 1716.

Before it was given to Alonzo, the Serpent was part of the fleet of Olivier Levasseur. Impressed by Alonzo's courage and determination after rescuing him from Captain Barnes, Levasseur gave the Serpent to the released pirate. Alonzo briefly used this ship, before claiming the larger schooner, the Wanderer as his own.
