Meanwhile, as we only asked for drafts strong enough to bring companies up to the established war strength, without taking into account the above extraordinary leakage, the drafts we received did not bring companies up to their proper strength in action. The reason why the lines of communication in the field[19] took so large a number away from our fighting-line was that we had no proper communication units, and the large working parties necessary for the light railway, road and bridge work had to be drawn from the fighting troops. It was entirely owing to the care with which the commanding officers on the line of communications—especially those in the engineers—had been selected that we were able to fight, and at the same time to make roads of some hundreds of miles’ length for intercommunication between corps. For instance, at the end of 1904 and the beginning of 1905, when the 1st Army was south of the Hun Ho, out of 180,000 men, 7,000 were on the line of communications. At the beginning of July, 1905, when the strength of the 1st Army had gone up to 250,000, and the communications stretched back a length of 150 miles to the River Sungari, there were 10,000 men employed on them—_i.e._, 4 per cent. of the army’s strength. The length of the road made on the Hsi-ping-kai positions by the 1st Army alone amounted to 1,000 miles, with bridges of more than 20 feet breadth and 50 feet span, and nearly 40 miles of embankment. Though the greater part of this was done by hired Chinese labour, even in this comparatively quiet period the troops of the 1st Army were on “works” for a period of 30,000 working “man days.”[20]
