[T]he Martians dead! slain by the putrefactive and disease bacteria against which their systems were unprepared; slain as the red weed was being slain; slain, after all mans devices had failed, by the humblest things that God, in his wisdom, has put upon this earth. . . . But there are no bacteria in Mars, and directly these invaders arrived, directly they drank and fed, our microscopic allies began to work their overthrow. Already when I watched them they were irrevocably doomed, dying and rotting even as they went to and fro. By the toll of a billion deaths man has bought his birthright of the earth, and it is his against all comers; it would still be his were the Martians ten times as mighty as they are. For neither do men live nor die in vain.
