Bernard Martin, left, and Shelley Bryant found a cannonball during a hike in Petty Harbour, which they believe could be from the 1690s. The couple came across the finding at Graveyard Ridge between Petty Harbour and Maddox Cove around the east side of Miner's Pond. Perfectly round," Martin told CBC Radio's On The Go Thursday. Martin began researching what could have brought the cannonball to Petty Harbour and came across the stories of Pierre Le Moyne d'Iberville. The Frenchman went on to besiege St. John's, burned houses in the city and had a prisoner scalped in a successful effort to force surrender from the English.
