The Battle of Tulifinny, also known as Battle of Deveaux Neck, was an American Civil War engagement fought December 6–9, 1864 in South Carolina during General Sherman's March to the Sea, also known as the Savannah Campaign. Outnumbered 5-1 a Confederate force successfully defended a critical section of the Charleston-Savannah railroad.
This engagement was historically significant because it was one of the rare occasions when United States Marines fought in combat during the Civil War, in addition the Confederate forces included the entire Corps of Cadets from the South Carolina Military Academy (now The Citadel), who comprised more than a third of the Rebel force; it is also the only occasion that the entire student body of a U.S. college fought in combat.
