According to a report from The Washington Post, organizers of the Civil War reenactment which took place in on a rolling patch of grass 80 miles west of Washington, D.C. over the weekend, the battlefield had to be temporally cleared because a suspicious device, possibly a pipe bomb, was found. The event organizers also admitted they had received a letter threatening "bodily harm" to attendees.
I was actually there, as a reenactor. My group was about 50 feet away from where the pipe bomb was found. We had supper cooking on the campfire, and around 4pm, VA State Troopers asked us to move about 50 feet away. Over an organizer's walkie, I overheard them say a device was found in the activities tent.
We waited along a path between camps for about 30 minutes before troopers asked us to move another 50 feet away. No one knew what was really happening. Everyone who camped in that section was completely displaced. Another 20 minutes passed, and they asked us to go across the battlefield to the other encampment. (One side of the battlefield held the Union camps and the other held the Confederate, the Sutlers (think outdoor shops), the activities tent, and the Living History section (think demonstration camps of both Union and Confederates).
Our group was confused, with little to no information. So we decided to head to our sister regiment to see if they would take us in for the time being. Our group is a Regimental Band, which is why we camp in Living History, and our sister group are infantrymen.
Our small gaggle of 10 walked aimlessly until we found info as to where our sister group was. We, unfortunately, couldn't find them. Turns out only a small portion of that group came. Disheartened, we asked another group if they had any room. They, and a couple other groups, provided us with food (our supper was on the fire back near the bomb), tents, blankets, and wine.
Around 10:30 it was announced that we were clear to make our way back to camp. Tired, cold, and worn out, we made the trek back to our camp where we were informed that the camps were not checked by police (there were tons of tents to check), and that we were to check our camps ourselves. And should another bomb be found, that it may be motion activated...
Luckily, no other bombs were found and no one was hurt. The latest rumors, at that time, were that 4 individuals were involved and that 2 were arrested, and 2 were on the run.
Crazy world out there....
