Book excerpt: The Louisiana Tigers in the Gettysburg Campaign, June -- July 1863, is the definitive account of General Harry T. Hays's remarkable brigade during the critical summer of 1863. While previous studies of the "Louisiana Tigers" have examined the brigade, or its regiments, or its leaders over the course of the American Civil War; and others have concentrated on its one-day role defending East Cemetery Hill on July 2, 1863, The Louisiana Tigers in the Gettysburg Campaign is the first account to focus exclusively and comprehensively on the role the "Louisiana Tigers" played during the 1863 Gettysburg Campaign in its entirety.
