During the height of that transatlantic excursion season of ours the men on board slept in three shifts of eight hours each; they had two meals a day. Their warm bodies were close-packed, breathing into one another's faces, in tiers of low-ceilinged rooms, for from seven to ten days, after the healthy life of the training camps which had accustomed their lungs to fresh air. When the transport passed into the harbor mouth, and the submarine danger was over, as ants might swarm out of their runways to the top of a hill they swarmed on deck, where first- and second-class passengers had sauntered and promenaded, in solid masses of khaki, who formed the most valuable and superior first-class passengers America had ever sent to Europe. They had arrived. They made the harbor echo with calls and hurrahs. Theirs had been a passage which money could not buy or would want to buy for more than one experience; a passage not for pay or adventure, whose glamour was a sight of the sea and of France and of all they had read about the war. They were man-power, man-power by its thousands and millions, formed in a common mold no less than egg-grenades, their clothes cut according to the same pattern no less than their gas masks, the man-power which we had to give if we did lack artillery and aeroplanes, automata who were sentient parts of a machine responding to the mechanism of orders rather than of levers. Equipped, disciplined, trained, hardened, the preparatory processes of the training camps sent them to us for the final processes in France. Mighty lighters hurried alongside the transport, whose time must not be wasted while the hundreds of thousands of other passengers waited three thousand miles away. Swiftly, more swiftly than any but human cargo could be unloaded, they were disembarked, the decks and the hold becoming strangely empty with the resounding footsteps of the officers and crew in place of the hum of conversation and the atmosphere of human bodies crowded together.
