On Returning to the Front after Leave

Apart sweet women (for whom Heaven be blessed),
Comrades, you cannot think how thin and blue
Look the leftovers of mankind that rest,
Now that the cream has been skimmed off in you.
War has its horrors, but has this of good —
That its sure processes sort out and bind
Brave hearts in one intrepid brotherhood
And leave the shams and imbeciles behind.
Now turn we joyful to the great attacks,
Not only that we face in a fair field
Our valiant foe and all his deadly tools,
But also that we turn disdainful backs
On that poor world we scorn yet die to shield —
That world of cowards, hypocrites, and fools.
