Why did the South Carolina settlements of San Miguel DE Guadalupe San Felipe and charlesfort fail?

The South Carolina settlements of San Miguel de Guadalupe, San Felipe, and Charlesfort failed primarily due to harsh environmental conditions, supply shortages, and conflicts with Indigenous peoples. The settlers struggled with inadequate food supplies and poor relations with local tribes, which led to hostility and violence. Additionally, internal discord and the lack of a sustainable economy further contributed to the collapse of these early attempts at colonization in the region. Ultimately, these factors made it difficult for the settlements to thrive and sustain themselves.
