However, I wouldn't be surprised if someone discovered signs of Confederate activities at either the mouth of the Sabine or Neches Rivers as they would have been prime routes for Union gunboats and transports into the eastern interior of the state. I believe that was the goal of the Bank's Expedition that was blown apart at Sabine Pass.
I remember when I was commuting from the old Port Acres community (boyhood home) to Lamar "Tech" in the early 1950s we'd occasonally goof-off enroute by going through the old Spindletop oil field (still had a number of timber derricks dating from the boom in the early 1900s) and somewhere amid them was a Texas historical marker for the Confederate Camp site on "Spindletop Hill." Supposedly, it was one of the highest points--and therefore considered "healthful" in the marshy country--in Jefferson County. According to local legend and lore, the ground had sunk (depending on the teller of tales) something like 15'-20' as the oil was pumped off the top of the salt dome and it subsided to today's level. In so far as I know, the only sites in Jefferson County with a connection to "THE Wah" were Sabine Pass and Spindletop Hill. Do I understand there were other sites???
