The research of John A. Boyd tracks all known pirate activity on the island of St. Croix. Many pirates brought treasure to the island as did smugglers and merchants. It is well documented that Captain James Martel was killed on the island and half of his fortune lost to time so he certainly rates a Chapter. Owen Lloyd took the treasure of Nuestra Señora de Guadelupe. Part of Lloyd's treasure was buried on the island and this stash became his bank until he was murdered in Christiansted. His story has been retold for centuries as part of Robert Luis Stevenson's book, Treasure Island. Only a small amount of this treasure remains on St. Croix so his chapter is small. By far the biggest fortune that probably remains hidden on St. Croix is the vast amount of wealth amassed by Jean La Vasseur while Governor of Tortuga. During his reign, 1640 to 1652, he took a minimum of ten percent of all of the prizes captured by the Buccaneers of Tortuga referred to as the Brethren of the Coast. He also collected taxes on all imports to the island. However, he cheated his partner in this criminal empire, Governor Phillippe de Lonvillers dePoincy of St. Croix, by keeping everything for himself. De Poincy retaliated by conquering Tortuga and claiming the Fortune of La Vasseur as his own. After de Poincy's military conquest of Tortuga, this treasure is also lost to time. The research for this book brings that fortune to St. Croix where it is probably still well hidden.
