From Six Weeks, the book about British junior officers in World War I that I've mentioned before, here is a stanza from a poem by Sub-Lt. A.P. Herbert, who fought at Gallipoli, and later saw his battalion destroyed at the Somme:
We only want to take our wounds away
To some shy village where the tumult ends,
And drowsing in the sunshine many a day,
Forget our aches, forget that we had friends.
I really like those lines. The emotion they convey is more complex than it may first appear, especially the last five words.
Thomas E. Ricks covered the U.S. military for the Washington Post from 2000 through 2008.
