Why did Champlain send someone to live the algonquin?

Champlain sent someone to live with the Algonquin to strengthen alliances and gather intelligence about the region and its inhabitants. By establishing a closer relationship with the Algonquin, he aimed to secure their support against common enemies, particularly the Iroquois. This also facilitated trade and cultural exchange, which were vital for the success of French colonial endeavors in North America.
