Moïse Vauquelin (?? - 1670), also known as Moses Vanclein was a famous French buccaneers during the 17th century that was known to have sailed with the likes of Francois L'Ollonais as well as Pierre le Picard during the height of the Buccaneering Era. Vauquelin moved to the West Indies around 1650 from the city of Normandy in France.Moïse Vauquelin or Moses Vanclein (fl. 1650-1670) was a 17th-century French buccaneer. During his four-year career as a privateer, he served as an officer under l'Ollonais and formed a brief partnership with Pierre Le Picard. He and Philippe Bequel later co-wrote a book detailing their explorations of the Honduran and Yucatán coastline. He was part of a buccaneering fleet being organized by l'Ollonais at the pirate haven of Tortuga and which would loot and plunder Spanish settlements throughout the Spanish Main during the next two years. Vauquelin was one of several officers serving in this expedition and was present at the raids against Maracaibo and Gibraltar in 1666 and Puerto de Cavallo and San Pedro in 1667.l'Ollonais and his fleet eventually split up, arguing over l'Ollonais desire to sail for Guatemala, shortly after the capture of a Spanish ship off the coast of the Yucatán. He and Pierre le Picard chose to leave the expedition, some accounts suggesting they were the ringleaders and instigators of the fleet's disbandment, and began privateering together for a time. Sailing along the coast of Costa Rica, he captured the town of Veraguas although he was driven from the area when he failed to take the nearby town of Nata and the two split up soon after. This defeat was later recorded in Alexander Esquemeling's The Buccaneers Of America almost twenty years later.Vauquelin seems to have lost his ship after this, although the circumstances are unrecorded. He did, however, manage to join the French privateer Chevalier du Plessis later that year. After du Plessis' death, Vauquelin was elected as his successor by the crew. He and his crew were able to successfully capture a Spanish prize, carrying a large cargo of cacao, near the port of Havana, Cuba before returning to Tortuga. In 1670, he and fellow buccaneer Philippe Bequel wrote an account of their careers at the Vice-Admiral Jean d'Estrées. The book contained detailed information of the geography of the Caribbean and West Indies, particularly the coasts of Honduras and the Yucatán, which were used by the Royal French Navy as well as later buccaneers.
