On October 5, 1781 the Little Jack was making its way to Quebec and had arrived at the eastern end of the Gut of Canso. Captain Peter Richard Tonge commanded the Jack, a tiny, full-rigged ship of 160 tons carrying 10 nine-pounders and 4 six-pounders. Captain Tonge was a seaman of considerable experience and a capable officer. Taken completely by surprise, Tonge was confronted by two rebel privateers. Outmanned and outgunned, Tonge had no choice but to try to outrun his pursuers. He made for Petit de Grat inlet only twelve miles from the Gut of Canso, but the American privateers followed. .
Tonge developed a desperate strategy. He anchored the Little Jack where the channel was most narrow and using a spring cable the ship was pulled around so that she blocked the channel thus forcing the Americans to enter one at a time. The battle was joined and although the Little Jack held her own, she was still overwhelmed by the superior firepower of the privateers.
Tonge’s next move was to land a nine-pounder cannon. It was no easy task to maneuver such a large gun out of the ship and haul it to higher ground, but they did and the advantage shifted to the Little Jack. She proceeded to drive one of the privateers out to sea and pounded the other’s main mast, sails, and rigging until she surrendered. Tonge set the American sailors free, repaired their ship and took it in tow to Quebec where she sold for 103 pounds.
