Up and down the ward, with swift precision, nurses move softly. They have the unanxious eyes of those whose days are mapped out with duties. They rarely notice us as individuals. They ask no questions, show no curiosity. Their deeds of persistent kindness are all performed impersonally. It's the same with the doctors. This is a military hospital where discipline is firmly enforced; any natural recognition of common fineness is discouraged. These women who have pledged themselves to live among suffering, never allow themselves for a moment to guess what the sight of them means to us chaps in the cots. Perhaps that also is a part of their sacrifice. But we follow them with our eyes, and we wish that they would allow themselves to guess. For so many months we have not seen a woman; there have been so many hours when we expected never again to see a woman. We're Lazaruses exhumed and restored to normal ways of life by the fluke of having collected a bit of shrapnel--we haven't yet got used to normal ways. The mere rustle of a woman's skirt fills us with unreasonable delight and makes the eyes smart with memories of old longings. Those childish longings of the trenches! No one can understand them who has not been there, where all personal aims are a wash-out and the courage to endure remains one's sole possession. The sisters at the Casualty Clearing Station--they understood. The Casualty Clearing Station is the first hospital behind the line to which the wounded are brought down straight from the Dressing-Stations. All day and all night ambulances come lurching along shell-torn roads to their doors. The men on the stretchers are still in their bloody tunics, rain-soaked, pain-silent, splashed with the corruption of fighting--their bodies so obviously smashed and their spirits so obviously unbroken. The nurses at the Casualty Clearing Station can scarcely help but understand. They can afford to be feminine to men who are so weak. Moreover, they are near enough the Front to share in the sublime exaltation of those who march out to die. They know when a big offensive is expected, and prepare for it. They are warned the moment it has commenced by the distant thunder of the guns. Then comes the ceaseless stream of lorries and ambulances bringing that which has been broken so quickly to them to be patched up in months. They work day and night with a forgetfulness of self which equals the devotion of the soldiers they are tending. Despite their orderliness they seem almost fanatical in their desire to spend themselves. They are always doing, but they can never do enough. It's the same with the surgeons. I know of one who during a great attack operated for forty-eight hours on end and finally went to sleep where he stood from utter weariness. The picture that forms in my mind of these women is absurd, Arthurian and exact; I see them as great ladies, mediaeval in their saintliness, sharing the pollution of the battle with their champions.
