> *As we emerged from the woods into an open space or field where our mounted skirmishers were deployed, it was clearly discovered that our troops were confronted with a heavy line of infantry, who, with weapons of a longer range than that of our carbines, were dismounting our men at a fearful rate, whilst they were unable to inflict any punishment upon the enemy. As Colonel Devin approached the skirmish line, he at once became the target for the Rebel sharp shooters and, the way the minnie balls were whiz…READ MORE

Lee also sought to take the war out of the ravaged Virginia farmland and gather supplies for his Army of Northern Virginia. Using the Shenandoah Valley as cover for his army, Lee was pursued first by Union Maj. Gen. Joseph Ho…READ MORE

John B. Gordon suggested to Lee the possibility of a successful offensive strike against Grant. In front of Gordon's men, Union-held Fort Stedman seemed the best target for a Confederate a…READ MORE
