Location of the Field Hospitals During the Battle of Gettysburg

The Story

In the first days of July 1863, the fields and farmhouses south and east of Gettysburg were transformed into a vast open-air hospital as the Army of the Potomac's Medical Department fought to save thousands of wounded men. Under the reforms of medical director Jonathan Letterman, the army had built a system of forward field hospitals, ambulance corps, and triage that was tested here at an unprecedented scale. This ground in Straban Township marks where surgeons worked around the clock amid the aftermath of the war's bloodiest battle.

Why it matters

Gettysburg's field hospitals proved the value of organized battlefield medicine, and the Letterman system pioneered here became the template for military and emergency medical care that endures to this day.

Camp Letterman

Straban Township, PA

In the sweltering weeks after the Battle of Gettysburg in July 1863, the fields east of town became Camp Letterman, the largest field hospital of the Civil War, where thousands of wounded soldiers from both armies were treated in orderly rows of tents. Named for Dr. Jonathan Letterman, the Army of the Potomac's medical director whose battlefield-evacuation system revolutionized military medicine, the camp combined surgery, convalescence, and an adjoining cemetery. The fragment quoted here — a grim bedside note that a soldier's recovery 'is yet doubtful' — captures the daily uncertainty that hung over the men who lay here through the summer and fall.

Gettysburg Battlefield

Gettysburg, PA · est. 1895

Lee's second invasion of the North ended here in three days of fighting that left over 50,000 casualties. Four months later Lincoln redefined the war's purpose in 272 words.

The Opera House

Westminster, MD

This Westminster landmark went up in 1845 as a hall for the Independent Order of Odd Fellows, one of the fraternal lodges that anchored civic life across small-town America in the early republic. Doubling as an "opera house" and community center, it hosted the performances, lectures, and gatherings that passed for a town's cultural heart for the better part of a century. During the Civil War, with Maryland a divided border state and armies crisscrossing the region around Gettysburg, the building reportedly served Union troops.

Mason-Dixon Crown Marker

Manheim Township, PA

The Mason-Dixon Line began as the peaceful settlement of a long and bitter boundary quarrel between the Penn family of Pennsylvania and the Calverts of Maryland. Between 1763 and 1767 the English surveyors Charles Mason and Jeremiah Dixon ran the line westward with remarkable precision, setting stone markers as they went; at every fifth mile they planted an ornate "crownstone" carved with the coats of arms of the two proprietary families. A crown marker like this one, re-dedicated in 1984, honors that painstaking survey and the famous boundary it fixed across the York County countryside.
