“War is not two great armies meeting in the clash and frenzy of battle. War is a boy being carried on a stretcher, looking up at God’s blue sky with bewildered eyes that are soon to close; war is a woman carrying a child that has been injured by a shell; war is spirited horses tied in burning buildings and waiting for death; war is the flower of a race, battered, hungry, bleeding, up to its knees in filthy water; war is an old woman burning a candle before the Mater Dolorsa for the son she has given.”
