On July 1st, the Union First Corps fought a successful delaying action west of Gettysburg, which bought time for the rest of the Army of the Potomac to move to the vital high ground south of town. This battle walk follows the actions of the First Corps artillery batteries in order to trace their contributions to the fight. The tour will include approximately one mile of walking through fields and some rough terrain. Meet at the West End Guide Station on U.S. Route 30.
