What caused the abandonment of Fort St. Louis?

• A. Attacks by Karankawas
• B. Disease
• C. Flooding
• D. Shortage of supplies

Answer: (A)

Frontier forts were abandoned when attacks from Indigenous groups made living there untenable. Fort St. Louis faced repeated raids by the Karankawa, which damaged the settlement, disrupted supplies, and eroded morale. Those assaults made it impossible for the colonists to stay safely, so the remaining settlers withdrew. While disease and shortages of food and tools were challenges, the immediate cause of evacuation was the danger and damage from the Karankawa attacks. Flooding wasn’t a factor in this case. This illustrates how conflict with local peoples could end a frontier outpost.
