"...the War Council was a sort of inner Cabinet, starting out with Root, Herrick, Ballinger, and the most senior officers of the Army and Navy. It was here where Hadley's experience as a Governor came in handy, as by January of 1914 he had taken over essentially most civilian-related aspects of the executive branch while Hughes turned his focus largely to coordinating the running of the war. Like the rest of the executive branch, the War Council met every day at the unused Merchants' Exchange Building, which Hughes facetiously called "the field White House," and the dominant personalities of the remainder of the conflict can see their influences traced to the very earliest meetings there in late September.
Hughes had mulled sacking Herrick as early as the train ride into Philadelphia but did not want to start a panic throughout the armed forces at a time of such fragile morale and instead began to slowly box his Secretary of War out, dealing directly with Wotherspoon and his chief aide, Bliss. It was the junior general who impressed Hughes, and Root for that matter, and they resolved that sometime soon, they would quietly ask Wotherspoon to retire to allow his more capable lieutenant to take the job of Chief of Staff. To his credit, Wotherspoon did perform capably and contrary to his reputation as "William Worthless-spoon" in the early weeks of the war, aggressively coordinating with regional garrison commanders, the infamously lead-footed Ordnance Bureau, and National Guards to bring as much mobilized force to the frontlines as possible by the end of the month, and a potential disaster at Harrisburg was averted thanks to his routing nearly the entire strength of the Northeast to central Pennsylvania even as Baltimore was falling into enemy hands.
Nonetheless, Bliss showed his mind for organization and strategy in those early meetings. It was Bliss' idea to look back to the War of Secession and not repeat the mistakes made then; first and foremost, he encouraged the civilian leadership to think in terms of strategic theaters, defined loosely by river systems, and three Army field commands were formed accordingly that would work independently under individual commanding generals but as part of a coordinated, grander strategy. In the east, the Army Command Susquehanna was created to prevent the Confederates from advancing any further north, placed under one of the most senior serving generals in the Army and a native Pennsylvanian, Hunter Liggett. Army Command Ohio was formed to attack the Confederate Midlands, placed under the purview of Charles Farnsworth, and finally Army Command Colorado, to coordiante all actions in the Southwest along the Texan and Mexican frontiers, under Charles Treat, though Hughes suspected that the forces under John J. Pershing in the western Arizona Territory would largely operate as they saw fit with little input from Treat's command post in Santa Fe.
Bliss' thinking in organizing the Army commands this way was that it aligned with the strategic realities of the various theaters of war and allowed various commanders to think on their feet accordingly in terms of pursuing their objectives. Further, he made a compelling case to the War Council that the Midlands were the true objective of the war and if the Confederates could be held off in southern Pennsylvania through winter, then a massive offensive into Kentucky the following spring could rapidly break Confederate morale and warmaking capabilities. "The key to defeating the enemy," Bliss wrote in a memorandum, "is to thrust through the heartland of their industry, a belt from Louisville on the Ohio through the central Cumberland Valley all the way to the transportation key at Chattanooga and on to grand Atlanta herself."
Similar actions were taken navally, where the various squadrons of the Navy were organized into two commands, Atlantic under William Sims and Pacific under Henry Mayo. Both would report directly to Austin Knight, who was designated as Chief of Naval Operations not long thereafter..."
