Quotes: Self-Destructive Charge

Forward, the Light Brigade!'
Was there a man dismay'd?
Not tho'(though) the soldiers knew
  Some one had blunder'd:
Theirs not to make reply,
Theirs not to reason why,
Theirs but to do and die:
Into the valley of Death
  Rode the six hundred.
Alfred, Lord Tennyson, The Charge of the Light Brigade
