long-dreamed-of battle of manœuvre in the plain of the Scheldt. Guns, gas-smoke apparatus, and material had been collected during the summer lull; existing communications had been more or less improved, though the necessity for feeder-railways was not at all realised, tanks were not yet created, and the proportion of machine-guns to infantry was rather below actual requirements.
