The Battle of Blair's Landing saw a Confederate cavalry-artillery force commanded by Brigadier General Tom Green attack several Union gunboats led by Rear Admiral David Dixon Porter and soldiers in river transports under Brigadier General Thomas Kilby Smith in Red River Parish, Louisiana. Green's force attempted but failed to stop the retreat of Porter's and Smith's forces downstream in an action that was part of the Red River Campaign of the American Civil War. The only significant casualty during the fighting was Green, who was killed by an artillery round.
