Immediately after Bull Run McClellan had been summoned to Washington to command the army of the Potomac. In November, Scott, worn out by infirmity, and finding his authority slighted by "my ambitious junior," retired, and thereupon McClellan, while retaining his immediate command upon the Potomac, was made for the time General-in-Chief over all the armies of the North. There were, it should be repeated, two other principal armies besides that of the Potomac: the army of the Ohio, of which General Buell was given command in July; and that of the West, to which General Halleck was appointed, though Fremont seems to have retained independent command in Missouri. All these armies were in an early stage of formation and training, and from a purely military point of view there could be no haste to undertake a movement of invasion with any of them. Three distinct views of military policy were presented to Lincoln in the early days. Scott, as soon as it was clear that the South meant real fighting, saw how serious its resistance would be. His military judgment was in favour of a strictly defensive attitude before Washington; of training the volunteers for at least four months in healthy camps; and of then pushing a large army right down the Mississippi valley to New Orleans, making the whole line of that river secure, and establishing a pressure on the South between this Western army and the naval blockade which must slowly have strangled the Confederacy. He was aware that public impatience might not allow a rigid adherence to his policy, and in fact, when his view was made public before Bull Run, "Scott's Anaconda," coiling itself round the Confederacy, was the subject of general derision. The view of the Northern public and of the influential men in Congress was in favour of speedy and, as it was hoped, decisive action, and this was understood as involving, whatever else was done, an attempt soon to capture Richmond. In McClellan's view, as in Scott's, the first object was the full preparation of the Army, but he would have wished to wait till he had a fully trained force of 273,000 men on the Potomac, and a powerful fleet with many transports to support his movements; and, when he had all this, to move southwards in irresistible force, both advancing direct into Virginia and landing at points on the coast, subduing each of the Atlantic States of the Confederacy in turn. If the indefinite delay and the overwhelming force which his fancy pictured could have been granted him, it is plain, the military critics have said, that "he could not have destroyed the Southern armies--they would have withdrawn inland, and the heart of the Confederacy would have remained untouched." But neither the time nor the force for which he wished could be allowed him. So he had to put aside his plan, but in some ways perhaps it still influenced him.
