A well researched account, by Calvin Bryant, with access to several books on the subject in the Library of Congress. Not many viewers are aware the ancient eyewitness accounts have 5 French Ships being sunk in the St. Johns river, to deny their use by the Spaniards in 1565. I am unaware of anyone ever searching for the remains of these ships. One ship was sunk opposite Fort Caroline by the Spanish. The other French ships were sunk near the mouth of the St. Johns, being scuttled by the French who sailed back to France in two ships. For details google "Mattfeld Fort Caroline." A side note: A 16th century map exists showing the location of Fort Caroline on the south bank of the St. Johns River. To date (2023) the fort has not been found. This 16th century map shows a rather unique lake in the shape of a crescent, to the WNW of Fort Caroline. I located this crescent-lake a few years ago (2020) on a Google satelite map of the Jacksonville area. I am unaware of anyone identifying this rather unique crescent shaped lake. It is near the headwater of a Trout River (WNW of the city of Jacksonville) and near this lake is stream called 6 mile Creek, which eventually unites with a Ribault River, which, in turn, flows ESE to modern day Jacksonville. The 16th century map also shows a crescent shaped forest just west of the crescent lake, a forest which still retains its crescent forest shape (the Cary Forest).
