From the monument along Chambersburg Road:

This monument marks right of first position July 1, 1863, facing north and second position facing west, which the Regiment held from 11:30 a.m. until First Corps fell back. Last position on Seminary Ridge right resting on railroad cut.

July 2 and 3. Regiment was in line on left centre and on the 3rd assisted in repulsing the final charge of the enemy.

The monument shows Sergeant Ben Crippen shaking his fist at advancing Confederates. Crippen was killed bearing the flag, and his body not recovered during the retreat through the town on July 1st. He is assumed to be one of the “unknowns” in the National Cemetery.
