Answer:
To establish a new French colony in North America
Explanation:
Back in the 19th century, France sought to establish a new French colony in North America.
They believed that by capturing Mexico, they could establish a foothold and expand their influence in the region. So, their primary goal was to establish a new French colony rather than celebrating Cinco de Mayo, aiding the Union in the American Civil War, or collecting debts owed by Mexico.
