"Why in ----" the infantry was calling to the artillery. "Why in ----" the artillery was calling to the engineers. You may fill out the blank space of this cry of mutually dependent units with the kind of language which was not supposed to be, but sometimes was, used in the presence of chaplains. The infantry changed the object of their impatience when night stopped them wherever the end of that long day's work found them. They were not thinking of supporting artillery fire for the moment. The late September air was chill, the ground where they lay was cold. Their appetites were prodigious from their hard marching and fighting. Their hearts and thought were in their stomachs. Wasn't it the business of rolling kitchens to furnish them warm meals? It was past supper-time. Where in ---- were those rolling kitchens? After dark they surely need not be held back in apprehension of being seen by the enemy's artillery. Night had laid its supreme camouflage over all the area of operations. Under its mantle an activity as intense as that of the day must continue for all who supported the infantry. We might take an account of stock. Regimental, battalion, and company officers might move about freely along the front in familiarizing themselves with the situations of their commands. _Liaison_ which had been broken between different units must be re-established. The ground ahead must be scouted. Platoons and companies which had become mixed with their neighbors, and individual men who had strayed from their units, must be sorted out and returned. Gaps in the line must be filled; groups that had become "bunched" must be deployed; groups whose initiative had carried them forward to exposed points might have to be temporarily withdrawn,--all by feeling their way in the darkness. The sound of machine-gun fire broke the silence at intervals as the watchful enemy detected our movements. A shadowy approaching figure, who the men hoped was the welcome bearer of that warm meal from the rolling kitchens, might turn out to be an officer who directed that they stumble about in woods and ravines to some other point, or creep forward in the clammy dew-moist grass with a view to improving our "tactical dispositions," which does not always improve the human dispositions of those who have to carry out the orders.
