Company A, Washington Artillery
The battery was commanded at the Battle of Gettysburg by Captain Charles W. Squires.
From the marker:
July 3. Having but one gun it co-operated all day with Miller’s Battery. Advanced before daylight into position about 100 yards north of the Peach Orchard assisted in repelling skirmishers and took part in the cannonade preceding Longstreet’s assault. Moved several hundred yards to the left after the repulse of that assault to aid in resisting a countercharge if attempted. Withdrew soon afterward to the rear.
July 4. At 9 A. M. marched with the Battalion to Cashtown to reinforce the cavalry escorting the wagon train.
Losses not reported in detail.
