great British offensive, which I observed through the summer of 1916, often occurred to me during the Meuse-Argonne battle. In both a new army, in its vigor of aggressive impulse, continued its attack with an indomitable will, counting its gains by hundreds of yards, but never for a moment yielding the initiative in its tireless attrition.

The British were four months in preparing for their thrust on the basis of nearly two years' training in active warfare, with all their arrangements for transport and supply settled in a small area only an hour's steaming across the Channel from home. Behind their lines they built light railroads and highways. They had ample billeting space, and their great hospitals were within easy reach. They gathered road-repairing machinery and trained their labor battalions; built depots and yards; established immense dumps of ammunition and engineering material; brought their heavy guns into position methodically, and registered them with caution over a long period; set an immense array of trench mortars in secure positions; dug deep assembly trenches for the troops to occupy before going "over the top"; and ran their water pipes up to the front line, ready for extension into conquered territory.
