Powder magazine explosion at Fort Lyon in Virginia kills and injures dozens of New York artillerymen
In the early afternoon, a series of explosions rocked Fort Lyon on Eagle's Hill, south of Alexandria, Virginia. Eight tons of black powder in the main magazine exploded, along with thousands of rounds of small arms munitions and devastated the center of the camp. The garrison, members of the Third New York Artillery, suffered more than twenty deaths and more than a dozen badly injured in the accident. (By John Osborne)
