When, in the days that followed, the 200 British battalions that had attacked began to count the gaps in their ranks, the realisation came that, of the 100,000 men who had entered no man’s land, 20,000 had not returned; another 40,000 who had been got back were wounded. In summary, a fifth of the attacking force was dead, and some battalions, such as the 1st Newfoundland Regiment, had ceased to exist. The magnitude of the catastrophe, the greatest loss of life in British military history, took time to sink in.
