Fredericksburg
13 Dec 1862 — Burnside sends fourteen brigades against a stone wall on Marye’s Heights; 12,600 Union casualties buy nothing at all. Lee, watching: “It is well that war is so terrible, or we should grow too fond of it.”
THE MOMENT IN CONTEXT
Lee’s Maryland campaign and Bragg’s advance into Kentucky aimed at far more than territory, since a success on Northern or border soil might sway the autumn elections, gather border-state recruits, and encourage Britain to offer mediation. Chance then intervened when a Union soldier found a lost copy of Lee’s orders, which revealed that his army was dangerously divided. McClellan still attacked in stages at Antietam and kept large reserves idle, so Lee’s battered army was able to hold its ground and then withdraw safely, while Bragg likewise fell back after Perryville.
From Chapter 6 — Antietam and Emancipation of The American Civil War, 1861–1865 (SEP 1862).

Then ask the room: The Proclamation freed no one in the loyal states and couldn’t be enforced where it applied. Defend the claim that it was still the war’s most important single document. The argued answer is on the chapter page →
