A nation founded on liberty did not drift into war; it tore itself apart. The conflict began not on a battlefield, but with a cane cracking against bone on the floor of the U.S. Senate-the sound of debate ending for good. Following the lead of secessionist "fire-eaters," states left the Union and proudly built a new nation "thoroughly identified" with slavery. When the first mortar shell exploded over Fort Sumter, it was not a surprise. It was the start of a fight for the continent's soul.What followed was not one war, but many. In the East, it was a bloody chess match where the audacity of Robert E. Lee repeatedly paralyzed the Union's massive army. In the West, it was a brutal, grinding fight for the rivers that were the Confederacy's lifelines, a war that produced a new kind of hero in the relentless Ulysses S. Grant. But the war itself was transformed when Abraham Lincoln, acting as Commander-in-Chief, unleashed a weapon more powerful than any cannon: the Emancipation Proclamation. The war for Union became a crusade for freedom.This book peels back the layers of myth to reveal the war's brutal machinery. It descends into the man-made hells of prison camps and the terror of guerrilla raids where rules of combat collapsed. The final campaigns were a form of annihilation, as Grant's grim arithmetic and Sherman's "hard war" were designed to crush not just an army, but the will of a people. A slave-holding aristocracy was destroyed. A new, more powerful nation was forged in blood and iron. The United States was not preserved-it was violently reborn.
