Both Union Soldiers training at Ft. Warren and Confederate prisoners of war were quartered along this side of the fort, often in adjoining rooms. his area also contained a schoolroom, 1900-volume library, and a chapel which was used almost daily by the Southerners. Both groups battled monotony by playing football, pitching quoits, and engaging in group songfests. North-South tensions were often reflected in taunts between the soldiers. When Unionists sang "John Brown's Body," Confederates reminded them of the Union loss at Bull Run. In return, when news of General Grant's capture of Ft. Donelson reached Ft. Warren, Union soldiers paraded with a sign reading "Bull Run Outdone"
