One of the more interesting exhibits at the Springfield Armory National Historic Site is a Model 1861 rifle and bayonet left over from a lightning strike.
According to the tag on the rifle, a contract Springfield 1861 with a 1864-marked barrel equipped with a Confederate-made Tredegar socket bayonet:
During a thunderstorm, a sentry’s musket was struck by lightning which left it just as you see it. Despite the intense heat caused by the lightening, a regulation Civil War paper cartridge was found intact in the breech when the weapon was disassembled for cataloging and preservation. The identity of the sentry, who survived, is not known. It is believed that he was a Confederate since, while the rifle is a Springfield contract arm, the bayonet is apparently of Confederate manufacture.
Records relate the sentry walked away unhurt, but that the soles of the shoes were burned away.
