Battle of Shiloh
6–7 Apr 1862 — A Confederate attack at dawn nearly drives Grant into the Tennessee River. On the second day the fighting reverses. The battle produces 23,700 casualties, more than all previous American wars combined, and dispels any remaining illusion of a short war.

Layer records and reconstruction methods
The moment in context A blockade need not catch every ship to put pressure on a country. A merchant who risks capture or delay must pay more for freight and insurance, and the buyer must pay more in turn. As the Union navy grew from a few dozen ships to hundreds, the Confederacy received fewer useful supplies at higher prices. Bases taken along the coast served another purpose too: at Port Royal, enslaved people escaped to the fleet. Commanders then had to decide whether to return them to their claimants or protect their freedom.
