サムター要塞の戦い
In the two weeks following the Battle of Fort Sumter in April 1861, as sentiments in Tennessee shifted in favor of secession, Turney raised a regiment of troops, the First Tennessee Infantry (sometimes called "Turney's First" to distinguish it from a similarly-designated regiment). As Tennessee had yet to officially secede, Turney acted mostly in secret until early May, when the state aligned itself militarily with the Confederacy.
