If the attack succeeds, and the German trench is held by us, No Man’s Land can be searched. The wounded and dead are found, and but few are reported "missing." But if the attack fail, and the regiment has to retire to its own line, it becomes impossible for us to search that part of No Man’s Land, adjoining the German trench (for there is rarely any truce after a battle in this war), and so, it is impossible to find out whether those who have failed to return were killed, wounded, or taken prisoners. The comrades who saw them fall are probably killed, for the return is as fatal as the attack. If they come back wounded they are taken straight to the hospitals and so have no chance of reporting to their officers the fate of those whom they saw fall. Only the unwounded return to the regiment and, in a lost battle, these are few and know but little of what happened to those around them. They were excited and were fighting for their lives. They had no leisure to observe the fate of others. On one occasion our men took some German trenches opposite them and held them for some hours by desperate fighting, but before dusk had to retire. Many were left dead or wounded in the captured trenches, and many fell on the return journey. The few who got back to us unwounded could give very little information about individuals who were missing. They had been separated one from another and fighting hour after hour with desperation. All therefore who did not return to the regiment or dressing station, and whose bodies were not recovered, were reported as "Missing" unless declared dead by reliable eye-witnesses. The evidence of eye-witnesses must be carefully examined before a regiment dare report a soldier dead on the strength of it. During an attack a man is in an abnormal state of excitement and the observations of his senses are not entirely reliable. Men imagine they see things, and frequently make mistakes in identity. I have known many cases in which a man has sworn that he saw another being carried to the dressing station, yet the missing man’s body has afterwards been found near the German lines. The eye-witness simply mistook one man for another. No end of pain to relatives has been caused by these mistakes and a regiment rightly declines on such evidence to report a soldier as killed.
