“In the summer of 1919, Churchill planned and executed a sustained chemical attack on northern Russia. The cabinet was hostile to the use of such weapons, much to Churchill’s irritation. He also wanted to use M Devices against the rebellious tribes of northern India. ‘I am strongly in favour of using poisoned gas against uncivilised tribes,’ he declared in one secret memorandum. He criticised his colleagues for their ‘squeamishness’, declaring that ‘the objections of the India Office to the use of gas against natives are unreasonable. Gas is a more merciful weapon than [the] high explosive shell, and compels an enemy to accept a decision with less loss of life than any other agency of war.'”
