Pennsylvania provided over 323,000 men to the Union Army during the Civil War, the second largest total of any state. More than 23,400 Pennsylvanians took part in the Battle of Gettysburg. (see the States at Gettysburg) It was the largest contingent from any state north or south, making up over a fourth of the Army of the Potomac. Almost 5,900 men from Pennsylvania became casualties during the battle, the second highest total from the Northern states.
The commanding general of the Army of the Potomac at Gettysburg, Major General George Meade, and two of its eight corps commanders, Major General John Reynolds and Major General Winfield Hancock, were Pennsylvanians.
There are monuments to every Pennsylvania unit at Gettysburg, as well as to its leading commanders. Because there are so many Pennsylvania monuments they are listed on three pages:
Monuments to 69 Pennsylvania infantry regiments
Monuments to 5 artillery batteries
Monuments to 10 cavalry regiments
Pennsylvania also has the largest monument on the battlefield, the State of Pennsylvania Monument:
