Re-organization of British System on Western Front.— From 1914 up to the date of the first battle of the Somme (July 1916) the British administrative services had had no very severe tests, but had developed their system almost completely. In munitions, the British army was now better supplied than any other force in the field. It had control of its own railway services, and supplementing the French broad-gauge railway system on its front—which it had taken over and increased—had a system of light railways, and a greatly increased scale of motor transport. But the Somme battles showed that supply had been increased beyond the scale that transport could cope with. There followed in Nov. 1916 a reorganization of the system. One feature of this reorganization was good. The division of authority which put the administrative services really under two heads, one for the battle area and one for lines of communication, was done away with. The military railways, which had been hitherto somewhat starved, were reorganized according to the plans of a civilian expert and were generously supplied with staff and material. But here, what proved in the result to be a mistake in organization was made: railways were separated from the control of the quartermaster general (who kept control of other forms of transport) and put under a director-general of transportation. Thus there were two separate transport authorities.

complete reorganization of it, with the central idea of doing away as far as possible with the "earmarking" of motor vehicles for particular units or particular tasks and making its total strength completely mobile and elastic. Vehicles saved by this "pooling" were formed into a G.H.Q. motor reserve. In the spring of 1918 this G.H.Q. motor reserve was able to take up part of the traffic load and was largely responsible for saving the situation.
Light railways (q.v.) at one stage of the war were perhaps over estimated. There was an inclination to regard them as all-suf ficing. The British system ultimately gave to them what was considered their proper role, recognizing that they were most valuable when the fighting line was stabilized for some length of time, but tended to be less valuable as the war became one of movement. In the spring of 1918 the British army had 920 m. of light railways in operation; in the summer, 'co m. less. Its advance was planned on the principle of concentrating labour in pushing forward the broad-gauge railways and then the roads from them, trusting to motor transport and to horse transport to carry on the load from broad-gauge railhead. Earlier in 1918, controversy on the subject was keen and the French were in clined to take a differing view. The Germans were tied to light railways, for they had not the means to extend their motor traction.
But his administration had no functions of procurement, only of distribution. In some points of administration the dividing line between the zone of advance and the zone of supply was abolished, e.g., all motor transport and all light railways, wherever operating, were controlled from headquarters. The French system of supply and distribution was fashioned for war in the home country or near to it ; when it was transplanted (for instance to Salonika) it was adapted nearer to the British system. The American system put administration on the fighting line under an assistant chief of staff (G. 4) at G.H.Q., and on lines of com munication under a general commanding service of supply (cor responding in some degree to the old British inspector-general of communications). Under the American system the chiefs of the supply service were not at G.H.Q. but at the headquarters of service of supply.
