New maps were made, printed, and sent round--and quickly, since food and supplies depended on them.

"One breakdown on a narrow road, one failure of an important message over a telephone wire--and how much may depend on it!" "Yet thanks to intelligent and devoted work, to experience and resource, how little in these later stages of the war has gone wrong!" The fighting men, the Staff work, the auxiliary services of the British Army--the long welding of war had indeed brought them by last autumn to a wonderful efficiency.

And that efficiency was never so sharply tested as by the exchange of a stationary war for a war of movement.

The Army swept on "over new but largely devastated country," into unknown land, where all the problems, as compared with the long years of trench war, were new.

Yet nothing failed--"except the astounded enemy's power of resistance." So much from a first-hand record of the First Army's advance.
