Things had been going badly in the Services of Supply. There was congestion at the ports; construction work was not proceeding. In view of the enormous demands which would arise when we should have two million men, instead of the million we had planned, in the autumn, the situation had suddenly become most serious. Washington, with our own ports sensitive to delays at those on the other side of the Atlantic, had about decided to send General Goethals to France to take charge of the Services of Supply as a co-ordinate commander with General Pershing. This was a radical departure. It meant two commanders in France instead of one, directly responsible to Washington. Such divided authority in such a crisis stirred the apprehension of every soldier lest in a great crisis the fighting branch should not be supreme over every other branch which served its will and necessities. The simplest of military principles required that the commander of the forces at the front must command the whole, or his fearful responsibility for needless loss of life rested on inadequate authority. Harbord, Pershing's right-hand man, was the counter to Washington's suggestion; that major of cavalry, whom nobody knew in the days when Goethals was building the Panama Canal, would prove that we already had a Goethals of our own in France. Without going over the ground of the pioneer stages of the Services of Supply, covered in my first book, the requirement upon which all transport depended was construction. We must enlarge the plant which France offered us for our needs. This meant building new docks to accommodate the requisite shipping, webs of spur tracks, immense areas of warehouses at the ports and others inland to accommodate our supplies; plants for assembling our railroad locomotives and cars brought from home; repair shops for them, and for guns and gun carriages, ambulances and aeroplanes and automobiles, motor trucks, and all other vehicular transport. More important still, there must be repair shops for human beings--enormous hospitals for caring for the sick and wounded, who might come by the hundreds of thousands in a single month. Hospital trains must be ready for their transport from the front. Enormous bakeries must provide hundreds of thousands of loaves every day. There must be barracks for the nurses and all the workers; barracks for the aviators and helpers who were drilling; lighters for disembarking troops when they arrived; camps, where they could spend the night ashore. Railroad sidings must enlarge railroad capacity; more spur tracks must be built wherever we had railheads at the front, and regulating stations which should dispatch the trains to the railheads. Around quiet villages must arise temporary cities of our building, connected with all the other activities in a system which was punctual and dependable.
