How did Donnacona and the Iroquois people help Jacques Cartier and his followers when they first arrived in North America?
They helped them survive winter by giving them a tea with the
leaves of northern white cedar tree would cure scurvy which helped
them survive the long winter.
Also Chief Donnacona's 2 sons went to France with Cartier and

Iroquois and the French.
