You are in for a treat if you like bateaux, sunken fleets and so forth of the Seven Years War. I recommend you watch this. The blurb reads
There is a graveyard on the bottom of Lake George, New York, cultural resources from the French & Indian War (1755-1763). These skeletons are the remains of a submerged military wharf, dozens of bateau wrecks, and a missing 1960 research sub built to photograph 18th century shipwrecks. Follow underwater archaeologists as they investigate one of the great mysteries of the 18th century— The Sunken Fleet of 1758.
