The peace message reduced to essentials: each envying the other his castle, two knights do battle till there are ""only cows where their castles had been,"" then decide to settle down as friends. The war is more cartoonish than gruesome--the logic of the idea is what counts here; but the illustrations, in sturdy black line and outspoken colors, are handsomely designed and, in their creatively selected details, more eloquent than the text. An acceptable additional title on a perennially knotty theme.
