For a less sentimental view of both military adultery and death in combat, cf. Kipling's The Young British Soldier:

If the wife should go wrong with a comrade, be loath
To shoot when you catch 'em -- you'll swing, on my oath! --
Make 'im take 'er and keep 'er: that's Hell for them both,
An' you're shut o' the curse of a soldier ...

When you're wounded and left on Afghanistan's plains,
And the women come out to cut up what remains,
Jest roll to your rifle and blow out your brains
An' go to your Gawd like a soldier.
