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.
The story behind this marker
AI contextThe era
By the summer of 1863, the Civil War was two years old and had grown far bloodier than anyone in 1861 had imagined. Armies now numbered in the tens of thousands, and the rifled muskets and artillery of the era tore through bodies faster than any medical service had been built to handle. When the Army of the Potomac collided with Lee's Army of Northern Virginia at Gettysburg in the first days of July, the quiet farm country of Adams County became the setting for the largest battle ever fought on the continent.
Straban Township sat just east of that maelstrom. Here, on the gentle farmland beyond the fighting, barns, farmhouses, and open fields were pressed into service as the guns still thundered a few miles away. What looks today like ordinary Pennsylvania countryside was, for a few desperate weeks, one of the busiest centers of human suffering and human care in America.
This was also a moment of change in how armies treated their wounded. The improvised, chaotic response of the war's early battles was giving way to something new and deliberately organized — and Gettysburg would be its greatest test.
People & events
The name to know here is Jonathan Letterman, the Army of the Potomac's medical director. In the months before Gettysburg, Letterman had rebuilt the army's medical service almost from scratch. He created a dedicated ambulance corps to carry wounded men off the field, organized field hospitals by division, and pushed a system of sorting the wounded by the severity of their injuries so that surgeons could do the most good with the time they had.
At Gettysburg, that system met a staggering demand. Both armies together left tens of thousands of wounded men behind, and the medical department worked around the clock across a landscape of field hospitals stretched behind the lines. Surgeons operated for days with little rest, and the farms of townships like this one filled with the injured of both blue and gray.
When the armies marched away, the wounded could not. In the weeks after the battle, scattered field hospitals were gradually consolidated into a large general hospital of tented wards east of Gettysburg, where men too badly hurt to move were nursed, fed, and tended by surgeons, volunteers, and relief workers until they could recover or be sent home. This ground remembers not the charge or the cannonade, but the long, patient work of putting men back together.
Its place in the American story
What was pioneered under Letterman did not stay at Gettysburg. His approach — evacuate the wounded quickly by a dedicated ambulance service, sort them by need, and move them through a chain of increasingly capable hospitals — proved itself here on a scale no one had attempted before. Within a year, the framework was adopted across the entire United States Army.
That matters far beyond the Civil War. The core ideas Letterman put into practice — triage, organized evacuation, and tiered levels of care — became the foundation of military medicine for generations, and they echo today in the way modern emergency rooms, trauma centers, and ambulance systems handle a rush of casualties. The instinct to sort patients by urgency and get the most critical care first traces a direct line back to fields like these.
So while Gettysburg is remembered above all for deciding a battle, it also quietly reshaped how a nation cares for its wounded. The monument here marks the birthplace, at full scale, of a system that has since saved countless lives who never wore a uniform at all.
If you visit
This is a place that rewards quiet and imagination. There is no dramatic ridgeline or famous stone wall here — just the rolling farmland of Straban Township, east of the town of Gettysburg and a little removed from the crowded stops of the main battlefield. That's part of the point. Stand here and picture these open fields dotted with hospital tents and crowded farmhouses, and the sound not of muskets but of surgeons, stretcher-bearers, and the wounded.
Come as part of a larger Gettysburg road trip, after you've walked the more famous ground of the battle itself. Seeing the killing fields first, then this place of mending, tells the whole human story of what happened here in July 1863 — the wound and the healing side by side.
Give yourself a moment to read the marker and simply look around. The landscape has largely returned to farmland and quiet, which makes it easier, not harder, to feel the weight of what once filled it. It's a fitting spot to remember the men who worked here to save lives, and the ordinary countryside that carried an extraordinary burden.

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.
Amherst VA Artillery "Kirkpatrick Battery”
Straban Township, PA
On the rolling farmland east of Gettysburg, this tablet marks where the Amherst (Virginia) Artillery — Kirkpatrick's Battery of Nelson's Battalion — was posted during the three-day battle of July 1863. Attached to the artillery reserve of Ewell's Corps in the Army of Northern Virginia, the battery went into action with a rifled gun and three smoothbore Napoleons in support of Lee's assaults on the Union line. Hundreds of such cast-iron tablets were placed across the field to record exactly where each unit stood.
CS Chesapeake MD Artillery "Brown’s Battery"
Straban Township, PA
This monument marks the Confederate Chesapeake Maryland Artillery — Brown's Battery — of Latimer's Battalion in Johnson's Division of Ewell's Corps, Army of Northern Virginia, armed with four 10-pounder Parrott rifles. Marylanders who cast their lot with the South served in units like this one, which fought on the Confederate left during the battle of early July 1863. Gettysburg drew soldiers from across a divided nation, including border-state men fighting far from a home that had stayed in the Union.
54th NY “Hiram Barney Rifles” Kovacs+ / Both marker
Cumberland Township, PA
This monument honors the 54th New York Infantry, the "Hiram Barney Rifles," of the First Brigade, First Division, Eleventh Corps at Gettysburg. On July 1, 1863, the regiment fought on the northern field as part of the division holding the Union right, taking part in the hard combat that ended in a fighting retreat through the town to Cemetery Hill. Like many Eleventh Corps regiments, it was raised in New York with a strongly German-immigrant character.
