Was Operation Diadem or the Battle of Cold Harbor fought during the Civil War?
Battle of Cold Harbor The Battle of Cold Harbor was fought from May 31 to June 12, 1864, with the most significant fighting occurring on June 3. It was one of the final battles of Union Lt. Gen. Ulysses S. Grant's Overland Campaign during the American Civil War, and is remembered as one of American history's bloodiest, most lopsided battles. Thousands of Union soldiers were killed or wounded in a hopeless frontal assault against the fortified positions of Confederate Gen. Robert E. Lee's army.
Knoxville Campaign The Knoxville Campaign was a series of American Civil War battles and maneuvers in East Tennessee during the fall of 1863 designed to secure control of the city of Knoxville and with it the railroad that linked the Confederacy east and west. Union forces under Maj. Gen. Ambrose Burnside occupied Knoxville, Tennessee, and Confederate forces under Lt. Gen. James Longstreet were detached from Gen. Braxton Bragg's Army of Tennessee at Chattanooga to prevent Burnside's reinforcement of the besieged Union forces there. Ultimately, Longstreet's own siege of Knoxville ended when Union Maj. Gen. William Tecumseh Sherman led elements of the Army of the Tennessee and other troops to Burnside's relief after Union troops had broken the Confederate siege of Chattanooga. Although Longstreet was one of Gen. Robert E. Lee's best corps commanders in the East, he was unsuccessful in his role as an independent commander in the West and accomplished little in the Knoxville Campaign.
