The Story
When the Civil War began, battlefield medicine was a chaos of scattered wounded and improvised care. Jonathan Letterman, a career Army surgeon raised in Canonsburg, rebuilt it from the ground up: a tiered system of triage, dedicated ambulance and supply wagons, and an orderly chain to move the injured from the firing line to the rear. At Gettysburg his methods treated the wounded of both armies, and the framework he devised became the backbone of modern military medical evacuation.
Why it matters
Letterman's triage-and-evacuation system saved countless lives in his own war and still shapes how armies and emergency services move the injured today.
