Staying with our WWII theme from the last two days, this is a portion of the coastal defense along the Gulf. We are at the Gulf Island National Seashore where toward the Fort Pickens end where there are several of these defensive emplacements. Some are larger than this one but it is so cool to actually see a gun still in place. The bunker is under a dune. It appears that there were two guns, both still here and three anti-aircraft guns (not here) to protect them. I saw four separate batteries and I am sure there were many more. The Gulf was awash with German U-Boats.
