"There are no dangerous weapons; there are only dangerous men. We’re trying to teach you to be dangerous — to the enemy. Dangerous even without a knife. Deadly as long as you still have one hand or one foot and are still alive. If you don’t know what I mean, go read ‘Horatius at the Bridge’ or ‘The Death of the Bon Homme Richard’; they’re both in the Camp library.”
― Robert A. Heinlein, Starship Troopers
I'll get you part way there - Horatius at the Bridge:
Then out spake brave Horatius,
The Captain of the gate:
“To every man upon this earth
Death cometh soon or late.
And how can man die better
Than facing fearful odds . . .
