Thanks very much. My specific interest is in finding some mention of two Spanish mortars that were moved from the Castillo de San Marcos at St. Augustine. Maybe they were the two beyond the railroad bridge that were not yet mounted, I don't know. Those two mortars, which I call the "six flags mortars" were taken by the Navy and engraved with "Captured at Fernandina March ____ 1862 by Rer. Ad. Dupont."
Here are some more details on them:

Any more help you can give me on specifics of what kind of pieces were captured at Fernandina, would be most helpful.
