Beaufort was the site of the final shot of World War I: a 95-pound shell fired at 10:59:59 AM on 11 November 1918 from a 155mm howitzer nicknamed "Calamity Jane", belonging to Battery E of the U.S. 11th Field Artillery, which was entrenched east of the town. The target is uncertain, but was probably the railway between Metz and Sedan.
