Earlier this year, NOVA Parks opened the Mt. Defiance Historic Park on a ridge just west of Middleburg. On Saturday, the Union cavalrymen who lost their lives on the battlefield 156 years ago will be commemorated in granite. 

         During the day, 1st Maine Cavalry reenactors will recreate life in camp, explain their uniforms and equipment, give demonstrations of cavalry weapons, and talk about the crucial role of the horse in the war. 

         At 11 a.m. there will be a formal dedication ceremony for a monument to the unit near where their heaviest fighting took place. The 3,000-pound Portland gray granite memorial was commissioned by the 1st Maine Cavalry, Co. reenactment group as a memorial to the men killed during the battles of Aldie, Middleburg and Upperville at the start of the Gettysburg campaign in 1863.

         Historian Rich Gillespie, who helped develop the interpretive signage at the park, will lead guided tours of the battlefield at noon and 4 p.m.

         This is a free event.

         Mt. Defiance Historic Park is located at 35945 John Mosby Highway west of Middleburg, on the eastbound side of Rt. 50, west of Zulla Road.
