of King Louis and the Count of Vermandois, the Admiral of France. An illegitimate son of Louis XIV, Vermandois served as Admiral of the French fleet until his death in 1683, meaning the cannon would have been cast no later than 1683, the time when La Salle was preparing for his voyage. This was considered strong circumstantial evidence that the ship was La Belle. A serial number on the gun (and two others found in 1997) was later matched in a French archival record discovered by Dr. John de Bry with the numbers of four bronze cannons that had been loaded onto La Belle, providing definitive proof of the wreck's identity. The shipwreck may have been known to one or more local watermen before its discovery by archaeologists. During the 1996 excavations, Texas Historical Commission archaeologists observed direct evidence that one of the four bronze cannons known to have been on La Belle had been removed from the wreckage some time before the 1995 discovery of the wreck, possibly decades earlier. It was surmised that this may have been the action of a local shrimper who may have accidentally snagged and recovered the gun in his nets. The whereabouts of this cannon remain a mystery, and no other clear signs of prior artifact recovery were observed at the wreck site. Archaeological excavation The team of state archaeologists spent one month diving on the wreckage, documenting its extent and condition, and recovering a number of artifacts. Because of the historical significance of the wreck, and because of the dark waters of the Bay which severely limited visibility for divers, the decision was made to construct a cofferdam around the wreck site. This was a double-walled steel structure, with compacted sand between the two walls, surrounding the entire wreck. The 1.5 million dollar structure was paid for by the state of Texas, though private funding and federal grants would fund much of the subsequent excavation. After completion in September 1996, the water inside the cofferdam was pumped out and the ship was exposed to air for the first time in centuries. A much larger team of archaeologists, numbering around 20, had been assembled in the nearby town of Palacios and were charged with the complete excavation of the shipwreck, under the direction of Dr. Jim Bruseth. This endeavor lasted from July 1996 to May 1997, and was considered one of the most
