Confederate Cavalry.
Fort Grigsby, a small Confederate post during the Civil War, sat on the Neches River at present-day Port Neches, Texas.
Confederate Major Julius Kellersberg built the post in October 1862. It was to be but one of a series of posts built as river defenses to block a possible Union advance up the Neches River after the fall of Fort Sabine. Though it consisted only of mud embankments reinforced with upright pointed logs, the post was defended by two 24-pound guns overlooking a bend in the river. After the construction of Fort Manhassett, it was no longer necessary and was abandoned sometime after July 1863.
The site is located eleven miles Southeast of Beaumont in eastern Jefferson County.
