The original cache here was a nano. Now it is what a nano might want to be when it grows up.
The sign is gone thanks to hurricane Michael, but the cache is still there.
Since the sign is gone, I'm adding it's inscription:
"Near this site on March 20, 1863, Confederate soldiers commanded by Captain Walter J. Robinson repelled a landing by Union sailors led by Acting Master James Folger of the blockading vessel U.S.S. Roebuck. The 11-man scouting party of Union sailors was seeking to locate a southern civilian vessel near the "Old Town" spring, when they were reportedly ordered to surrender by Captain Robinson. During the ensuing skirmish, several Union sailors were killed and wounded as they fled to their launch boat. Quarter, or safe passage, was requested by the remaining Union sailors to retrieve their dead and wounded. Total Union casualties were six dead and three wounded. Union sailors buried four of the deceased on nearby Hurricane Island, and a fifth sailor was interred by the Confederate soldiers. No casualties were recorded by the Confederate unit, which later became Company A of the 11th Florida Infantry Regiment. After the conclusion of the Civil War, the remains of the Union sailors were removed to the national cemetery at Fort Barrancas."
