When the contingency arose, however, the plans were there; and the mobilization and transport to {25} France of our Expeditionary Force will remain on record as one of the most efficient military operations ever undertaken by any country. Second only to the rapidity and completeness with which the navy took command of the sea, were the speed and secrecy with which those first divisions were conveyed across the Channel. That in mere numbers they seem in retrospect to have been almost ridiculously inadequate is merely a measure of the colossal proportions that the war on land afterward assumed. Small as that army was, however, it was the largest force that we had ever sent oversea as a single undertaking; and it must be borne in mind that, in all probability, it was the most highly trained then in existence, and that its presence in France had both moral and material effects of almost incalculable importance. Nobody who lived, or was staying, near any of our great southern railway lines during those early days of August will ever forget the emotions roused by that endless series of troop trains, passing with such precision day and night; and of the feelings produced in France by this visible pledge of our friendship there was instant and abundant evidence. Between August 9th and August 23d five Divisions of Infantry and two Cavalry Divisions were safely landed in France; and when it is remembered what a single division consists of some idea may be obtained of what that accomplishment meant. Apart from the Headquarters' Staff with a _personnel_ of 82, requiring 54 horses, 2 wagons, and 5 motor-cars, it embraced three Infantry Brigades, Headquarters' divisional artillery, three brigades of {26} Field Artillery, one Howitzer Brigade, one heavy battery, a divisional ammunition column, the Headquarters' division of engineers, two Field companies, one Signal company, one Cavalry squadron, one Divisional train, and three Field ambulances--comprising a total _personnel_ of over 18,000 men, 5,500 horses, 870 wagons, 9 motor-cars, and 280 cycles, the number of guns, including machine guns, amounting to 100; and with a base establishment for each division of 1,750 men and 10 horses.
