Thomas Hardy's The Man He Killed

Had he and I but met
By some old ancient inn,
We should have sat us down to wet
Right many a nipperkin!

But ranged as infantry,
And staring face to face,
I shot at him and he at me,
And killed him in his place.

I shot him dead because—
Because he was my foe,
Just so: my foe of course he was;
That’s clear enough; although

He thought he’d ‘list, perhaps,
Off-hand like—just as I—
Was out of work—had sold his traps—
No other reason why.

Yes; quaint and curious war is!
You shoot a fellow down
You’d treat, if met where any bar is,
Or help to half a crown.
