The park will commemorate the 150th anniversary of the Battle of Prairie Grove. The original battle, fought on December 7, 1862, saw about 22,000 soldiers fighting most of the day, with about 2,700 killed, wounded, or missing. Every even-numbered year, Prairie Grove Battlefield State Park hosts a battle reenactment. During the weekend there will be many lead and self-guided activities including tours through the Union, Confederate, and civilian camps, various military drills, cooking, spinning, and lace making demonstrations along with other living history programs. “Sutlers Row” features a number of vendors selling 19th century reproduction, books, and souvenirs. The battle demonstration begins at 1 p.m. each day, featuring charges and counterattacks by Union and Confederate infantry and cavalry. The reenactment is held on the actual battlefield near the historic Borden House. Contact the park (closer to event time) for a detailed schedule. Reenactors, contact the park to register.
