This state of things continued until after the disastrous result to General George B. McClellan's army in the Seven Days' battles around Richmond. After those engagements General McClellan was superseded in the command of the Army of the Potomac by General John Pope. General Pope was from the Western Army, and upon taking command of the army in Virginia issued a high-sounding, pompous order in which he belittled the valor of the Confederate soldiers of the west, asserting he had "only seen the backs of the enemy," and his purpose in coming to this army was to lead it to victory and success. In that order he declared that he did not want to hear such phrases as "taking strong positions and holding them," "lines of retreat" and "bases of supplies," which he was told was common in the army. He declared that the glory of the soldier was in pushing the enemy and studying the lines of his retreat, which he then proposed to do. He announced his purpose to subsist the invading army by enforced supplies from his enemies, and, in order to prepare the world and give it some idea of his rapid movements and brilliant feats, issued orders from "headquarters in the saddle." This unique order, full as it was of boastings of what he had done and what he proposed to do, failed to frighten the Confederate commanders, as General Pope, no doubt, thought it would do. On the contrary, without loss of time they concentrated their forces, gave him battle and the Federal commander was ingloriously driven from the field, with great loss of men, arms and supplies. And so in less than sixty days from the time he took command of the army he was relieved by General McClellan, whom he superseded, having lost every engagement fought during the time. His advance through the counties of Fauquier and Culpeper to Fredericksburg, when he took command of the army, caused great consternation because of his unreasonable and cruel exactions. Many private citizens, who had never entered the Confederate service, were arrested upon their refusal to take the oath of allegiance to the United States government, and were ruthlessly dragged from their homes and confined in Northern prisons.
