Final answer:
Louis de St. Denis did not lead a French force to destroy Spanish missions in East Texas; rather, he was instrumental in French-Spanish relations and establishing missions.
Step-by-step explanation:
The statement that Louis de St. Denis led a French force to destroy Spanish missions in East Texas is False. Louis de St. Denis was actually a French explorer who played an important role in establishing French and Spanish relationships in the region, including founding a mission among the Hasinai in East Texas, but he did not lead forces to destroy Spanish missions. Instead, his role was more diplomatic and foundational for French presence in the area.
