Clarke attributes German restraint in battlefield gas warfare to fear of British retaliation. He claims Britain held the world's largest wartime stockpile, including nerve-agent bombs, and openly warned Germany that use would bring a response in kind. The stockpile's composition and relative size are assertions in this account, with no inventory or dated source supplied. He is unsure whether Britain went as far as showing Germany photographs. The deterrence argument rests on making the prospect of retaliation clear to the opponent.
