"OUR artillery and automobiles have saved Verdun," French officers and soldiers were continually telling me. And as I look back on two months of ambulance-driving in the attack, it seems to me that automobiles played a larger part than even the famous "seventy-fives," for without motor transport there would have been no ammunition and no food. One shell, accurately placed, will put a railway communication out of the running, but automobiles must be picked off one by one as they come within range. [6] This article was printed in the July issue of the _Cornhill Magazine_, and is reproduced by permission of the author and the publishers of the _Cornhill_. The picture of the attack that will stay with me always is that of the Grande Route north from Bar-le-Duc, covered with the snow and ice of the last days of February. The road was always filled with two columns of trucks, one going north and the other coming south. The trucks, loaded with troops, shells, and bread, rolled and bobbled back and forth with the graceless, uncertain strength of baby elephants. It was almost impossible to steer them on the icy roads. Many of them fell by the wayside, overturned, burned up, or were left apparently unnoticed in the ceaseless tide of traffic that never seemed to hurry or to stop. All night and all day it continued. Soon the roads began to wear out. Trucks brought stones from the ruins of the battle of the Marne and sprinkled them in the ruts and holes; soldiers, dodging in and out of the moving cars, broke and packed the stones or sprinkled sand on the ice-covered hillsides. But the traffic was never stopped for any of these things. The continuous supply had its effect on the demand. There were more troops than were needed for the trenches, so they camped along the road or in the fields. Lines of _camions_ ran off the road and unloaded the reserve of bread; the same thing was done with the meat, which kept well enough in the snow; and the shells, which a simple _camouflage_ of white tarpaulins effectually hid from the enemy airmen.
