times only to look again, closer, into the heart of it, staring at its scenes not as men who belong to them but as witnesses to give evidence at the bar of history--for if we are not that we are nothing--and to chronicle the things that have happened on those fields, this sense of impersonal forces is strong. We see all this in the mass. We see its movement as a tide watched from the bank and not from the point of view of a swimmer breasting each wave or going down in it. Regimental officers and men know more of the ground in which they live for a while before they go forward over the shell-craters to some barren slope where machine-guns are hidden below the clods of soil, or a line of concrete blockhouses heaped up with timber and sand-bags on one of the ridges. They know with a particular intimacy the smallest landmarks there--the forked branch among some riven trees that are called a "wood," a dead body that lies outside their wire, the muzzle of a broken gun that pokes out of the slime, a hummock of earth that is a German strong point. They know the stench of these places. They know the filth of them, in their dug-outs and in their trenches, in their senses and in their souls. I and a few others have a view less intimate, and on a wider scale. We go to see how our men live in these places, but do not stay with them. We go from one battle to another as doctors from one case to another, feeling the pulse of it, watching its symptoms, diagnosing the prospects of life or death, recording its history, as observers and not as the patients of war, though we take a few of its risks, and its tragedy darkens our spirit sometimes, and the sight of all this struggle of men, the thought of all this slaughter and sacrifice of youth, becomes at times intolerable and agonizing. This broad view of war is almost as wearing to the spirit, though without the physical strain, as the closer view which soldiers have. The wounded man who comes down to the dressing-station after his fight sees only the men around him at the time, and it is a personal adventure of pain limited to his own suffering, and relieved by the joy of his escape. But we see the many wounded who stream down month after month from the battlefields--for three and a half years I have watched the tide of wounded flowing back, so many blind men, so many cripples, so many gassed and stricken men--and there is something staggering in the actual sight of the vastness and the unceasing drift of this wreckage of war. So we have seen the fighting in the year 1917 in the whole sweep of its bloody pageant; and the rapidity with which one battle followed another after an April day in Arras, the continued fury of gun-fire and infantry assaults, and the long heroic effort of our men to smash the enemy's strength before the year should end, left us, as chroniclers of this twelve months' strife, overwhelmed by the number of its historic episodes and by its human sacrifice.
