There are monuments to seven batteries of Pennsylvania artillery represented on the Gettysburg battlefield, although due to casualties four of them had been merged at the time of the battle into two consolidated batteries. To make things more confusing, one of the consolidated batteries, C&F, chose to not only erect a monument for each of its component batteries, but placed a third, combined, monument at a secondary location on the field.
Battery H of the 3rd Pennsylvania Heavy Artillery also has an unusual tale. Assigned to the Baltimore Defenses, Battery H traded its heavy guns for field artillery and was assigned to guard river crossings and the railroad in Maryland. A section of two guns narrowly missed being swept up by Stuart’s Confederate cavalry and attached themselves for safety to passing Union cavalry, which brought them to Gettysburg.
