"A frangible grenade or Molotov cocktail used by the Japs consists of a bottle filled with a gasoline-base inflammable to which a glass cup containing red phosphorous is added. The device is 9½ inches high, 2½ inches in diameter and weighs 1½ lbs. To operate as a hand grenade, throw the bottle at a tank or pillbox in such manner that the cup containing the phosphorous strikes first. When the cup and the bottle break, the phosphorous ignites the gasoline". |
