What bluff did Oglethorpe overlook?

Oglethorpe overlooked the strategic bluff at Yamacraw, which was crucial for the defense of the colony of Georgia. He initially did not recognize its potential as a military and logistical advantage against Spanish forces from Florida. This oversight allowed for vulnerabilities in the colony's defenses, which could have been fortified had he taken advantage of the high ground. Ultimately, the bluff's significance became apparent as the settlement developed.
