"The Allied strategy in France had been a sanguinary mistake which nearly brought us to irretrievable defeat. When it failed the High Commands had no rational alternative to propose. The Allied generals were completely baffled by the decision of the Germans to dig in. They could think of nothing better than the sacrifice of millions of men in a hopeless effort to break through. Even then they had not worked out what mechanical aid was necessary to carry out such an operation, nor had they given any real systematic thought to the methods of providing their armies with the requisite machinery for putting into effect their hazy and crazy plans. How crazy were their ideas at this stage can be ascertained by reading the painful story of a succession of foolish offensives which for years were to mow down the flower of British and French youth by the million in vain efforts to rush machine guns, skilfully concealed and effectively protected. The primary responsibility for success or failure rested with Governments, and they could not shuffle off any part of that responsibility by pleading that they had placed their trust in experts who were obviously unequal to their task."
