A 22-gun British warship that sank during the American Revolution and has long been regarded as one of the “Holy Grail” shipwrecks in the Great Lakes has been discovered at the bottom of Lake Ontario, astonishingly well-preserved in the cold, deep water, explorers announced Friday.
Shipwreck enthusiasts Jim Kennard and Dan Scoville used side-scanning sonar and an unmanned submersible to locate the HMS Ontario, which was lost with barely a trace and as many as 130 people aboard during a gale in 1780.
The 80-foot sloop of war is the oldest shipwreck and the only fully intact British warship ever found in the Great Lakes, Scoville and Kennard said.
The finders of the wreck said they regard it as a war grave and have no plans to raise it or remove any of its artifacts. They said the ship is still considered the property of the British Admiralty.
The dark, cold freshwater acts as a perfect preservative, Smith said. At that depth, there is no light and no oxygen to hasten decomposition, and little marine life to feed on the wood.
The Ontario went down on Oct. 31, 1780, with a garrison of 60 British soldiers, a crew of about 40, mostly Canadians, and possibly about 30 American war prisoners.
The warship had been launched only five months earlier and ferried troops and supplies along upstate New York's frontier. Although it was the biggest British ship on the Great Lakes at the time, it never saw battle, Smith said.
Explorers have been searching for the Ontario for decades, and there have been numerous false finds over the years, said Eric Bloomquist, interpretative programs manager at Old Fort Niagara.
A rare feature that helped identify the ship: the two crow's nests on each mast. Another was the decoratively carved scroll bow stem.
