In March 1819, a Beothuk woman named Demasduit was kidnapped and taken from her tribe on frozen Red Indian Lake in central Newfoundland. She watched as the white men shot her husband, Chief Nonosabasut. They called her "Mary March," out of deference to the date of her capture. Less than two years later, she was dead. Within a decade, the entire tribe was extinct. IDEAS host Paul Kennedy examines what actually happened.
