Union troops advancing in darkness on Munson's Hill fire on each other, killing nine and wounding twenty-five

Confederate troops had abandoned Munson's Hill, over;looking Washington DC, the morning before.  Union troops were advancing in that area in the early hours of the morning when several units mistook each other for enemy and began firing on each other. Before the mistake could be discovered, nine men had been killed and around twenty-five wounded in this "friendly fire" incident.   (By John Osborne)
