WINDSOR, Ont. - A historic cannon has been found at the bottom of the Detroit River on the Detroit side.

A Detroit police dive team and the U.S. Coast Guard are working to recover the cannon that was found during a training exercise in July.

It was one of five British guns that were on a ferry that capsized in the river in 1796.

Three of the cannons were found in the 1980s and a fourth recovered in 1994.

This one is about two metres long and is estimated to weigh 540 kilograms.

The cannon will be put in storage until money can be raised to restore it.
