This was always part of local lore. A few years ago, repairs were needed to the church and the Archaeologist from the University of West Florida were able to dig under the flooring as it had to be replaced. I was in the Church during some of the digging. I saw artifacts that were designated as CW era. Some buttons had the US design on them. I'm sure any of the staff at UWF would be happy to discuss their find. They are very active and interactive with the public on the historical details they are into in this area.
My point is that the use of this Church as something other than a house of worship by the Union was proven.
