Mount Olivet Cemetery is at 725 S. Baltimore Street in Hanover, Pennsylvania. Founded in 1859, the cemetery sits atop high ground southeast of downtown, and is a natural gun position from a military perspective. During the afternoon phase of the June 30, 1863, Battle of Hanover, horse-drawn Confederate horse artillery rumbled up the slope from the southwest and unlimbered. Gunners moved the cannon into position and sighted their distant targets, with a particular emphasis on a line of Union artillery on the heights immediately north of Hanover. Fuses were cut to the length appropriate for the distance, and the rounds loaded. Lieutenants sighted the target through field glasses, while crewmen prepared the guns for firing. The orders came, and the resulting detonation of the powder sent sound waves reverberating off houses, rattling windows and fraying nerves of the remaining citizens.
Mount Olivet Cemetery is in the foreground. Rebel guns placed there had to fire over the town of Hanover (note the church spire) to hit Yankee guns on the ridge north of town (the thin line of dark trees next to the spire and below the background Pigeon Hills). Some of the shells fell short and struck the town, or exploded over it. (Left click on the photo to enlarge it for better detail).
