Although the evidence of the site has nearly vanished, Port Hudson, Louisiana, holds a distinct place in Civil War History. Located just north of Baton Rouge, the village was the last Confederate stronghold on the Mississippi River and the site of the longest genuine siege in American military history. In Port Hudson, Confederate Bastion on the Mississippi, Lawrence Hewitt offers a compelling account of the Confederate occupation of Port Hudson in August, 1862, and the Union's efforts to capture the stronghold, culminating in a final unsuccessful assault in May, 1863.
