The hundred soldiers and workers who accompanied Cadillac built a fort enclosing one arpent[12][13] (about 0.85 acres (3,400 m2), the equivalent of just under 200 feet (61 m) per side) and named it Fort Pontchartrain. Cadillac's wife, Marie Thérèse Guyon, soon moved to Detroit, becoming one of the first European women to settle in the Michigan wilderness. The town quickly became a major fur-trading and shipping post. The Église de Saint-Anne (Church of Saint Ann) was founded the same year. While the original building does not survive, the congregation of that name continues to be active today. Cadillac later departed to serve as the French governor of Louisiana from 1710 to 1716. French attempts to consolidate the fur trade led to the Fox Wars involving the Meskwaki (Fox) and their allies versus the French and their Native allies.
