ship daily to retrieve cargo, managing to salvage some of La Salle's papers and clothes, barrels of flour, casks of wine, glass beads, and other trade items. Before long, however, a strong southerly wind drove the hull into the muddy bottom, and soon only the rear deck remained above water. Of the 27 people originally assigned to the ship, the only survivors were Tessier, a priest, a military officer, a regular soldier, a servant girl, and a small boy. They remained on the peninsula for three months, as the only way to the fort was to walk through Karankawa territory. After a small Indian canoe washed ashore one day, the survivors were able to paddle across the bay and return to the fort. The destruction of their last ship left the settlers stranded on the Texas coast, with no hope of any assistance from the French colonies in the Caribbean Sea. Discovery by the Spanish The Spanish authorities learned of La Salle's expedition when a former member of the colony, Denis Thomas, was captured aboard a pirate ship. In an attempt to save his life, Thomas related that La Salle had planned to establish a colony near the Mississippi River and eventually take over Spanish silver mines. Although Thomas was quickly hanged, the Spanish believed his information to be reliable and began searching for the French colony. On December 25, 1686, a Spanish expedition led by Captain Martin de Rivas and Captain Pedro de Yriarte left Veracruz to sail along the Gulf Coast. On April 4, they reached Matagorda Bay and dispatched several canoes to explore the area. from their ship, they discovered La Belle, which they described as a "broken ship" with three fleur-de-lys on her stern. The Spanish salvaged two swivel guns and five cannons from the ship, as well as the anchor, some cordage, and the masts, which they made into oars. As final proof that this ship had belonged to the French colony, the expedition also discovered the campsite where the French survivors had lived for three months. Among the remains of the campsite were pages from books written in French. Rediscovery The wreck lay forgotten for over three hundred years in the dark murky waters of Matagorda Bay. In the 1970s, Kathleen Gilmore of Southern Methodist University analyzed historical accounts of the La Salle shipwrecks, and gave general guidance as to where they might be
