internal strife was over and the call of duty was triumphant. Already in the winter of 1915-16 I had come through that inner struggle. The will had asserted its incontestable mastery. Whereas in the early days I went into the fight with a cheer and a laugh, I was now habitually calm and resolute. And that frame of mind endured. Fate might now put me through the final test without my nerves or reason giving way. The young volunteer had become an old soldier.

This same transformation took place throughout the whole army. Constant fighting had aged and toughened it and hardened it, so that it stood firm and dauntless against every assault.
