Which lasted longer, the Battle of Chancellorsville or the Battle of the Wilderness ?
Battle of the Wilderness The Battle of the Wilderness, fought May 5–7, 1864, was the first battle of Lt. Gen. Ulysses S. Grant's 1864 Virginia Overland Campaign against Gen. Robert E. Lee and the Confederate Army of Northern Virginia in the American Civil War. Both armies suffered heavy casualties, a harbinger of a bloody war of attrition by Grant against Lee's army and, eventually, the Confederate capital, Richmond, Virginia. The battle was tactically inconclusive, as Grant disengaged and continued his offensive.
Tullahoma Campaign The Tullahoma Campaign (or Middle Tennessee Campaign) was a military operation conducted from June 24 to July 3, 1863, by the Union Army of the Cumberland under Maj. Gen. William Rosecrans, and regarded as one of the most brilliant maneuvers of the American Civil War. Its effect was to drive the Confederates out of Middle Tennessee and to threaten the strategic city of Chattanooga.
