Volunteers Chris Williamson, 23, left, and Cameron Owen, 16, get a taste of what trench life was like for soldiers during the Siege of Vicksburg during the 26th annual Living History program at the Vicksburg National Military Park. “That’s what they did when they weren’t fighting,” said David Slay, a doctoral student at Texas Christian University. “They sat out there in the hot sun and fried.” Vicksburg National Military Historian Terry Winschel said the park is offering interpretive programs like Living History seven days a week for the first time this summer.
