Quoted With Small Comment
Buzzflash has put together a page of quotes from eminent figures in history (some more eminent than others, granted), including this one at the top:
“It is only those who have neither fired a shot nor heard the shrieks and groans of the wounded who cry aloud for blood, more vengeance, more desolation. War is hell.”
- William Tecumseh Sherman, Union General in the American Civil War (1820-1891)
The whole list is worth at least skimming through.
