“Do your duty, you can do no more, you should wish to do no less”
Robert E. Lee in a letter to his son.

They did their duty.

“And Though you be done with to death, what then?
If you battled the best you could;
If you played your part in the world of men,
Why, the Critic will call it good.
Death comes with a crawl, or comes with a pounce,
And whether he’s slow or spry,
It isn’t the fact that you’re dead that counts,
But only, how did you die?”

Edmund Vance Cooke
