London was only seven hours away, but the hours on leave there seemed a year ago already. The men who had come back, after sleeping in civilization with a blessed sense of safety, had a few minutes of queer surprise that, after all, this business of war was something more real than a fantastic nightmare, and then put on their moral cloaks against the chill and grim reality, for another long spell of it. Very quickly the familiarity of it all came back to them and became the normal instead of the abnormal. They were back again to the settled state of war, as boys go back to public schools after the wrench from home, and find that the holiday is only the incident and school the more enduring experience.

There were no new impressions, only the repetition of old impressions. So I found when I heard the guns again and watched the shells bursting about Ypres and over Kemmel Ridge and Messines church tower.
