But credit for any success which may have been achieved, is, of course, mostly due to the loyalty and excellence of the staff who worked under my command. The doctors and the nurses never spared themselves, night or day, during times of stress of work, and adapted themselves admirably to unusual and difficult conditions. If the army had been advancing instead of retreating, they--the doctors and nurses--would have had more patients, but their work was of great value, when, and where, it was much needed. The cook was a marvel of good temper and adaptability. There was no need of a Daylight Saving Bill with her. It was never too late, or too early, for her to prepare food, when there was any to prepare, or to go without it cheerfully, when there was none. The chauffeurs (five men and one woman) performed miracles with the cars, and showed pluck and endurance such as is not often exacted from ambulance drivers. To have brought those Ford cars over those unique roads, from Barchinatz, in the north of Serbia, to Petch, near the Montenegrin frontier, with only one accident to one car, was a wonderful feat, and their work of evacuating wounded from our own, and from other field hospitals, was of inestimable value. The interpreter, George, did his best, but for practical purposes he knew no language but his own, and he could only read that in Croat characters. But Vooitch, a young Bosnian Serb, spoke French, German, English, and Italian, besides his own Serbian. His position was, for various reasons, not an easy one, but I never saw him out of temper, and by unfailing service to me, night and day, he did much to strengthen weak places elsewhere in the Serbian staff. He was invaluable. Our secretary, John Greenhalgh, had, owing to the circumstances of our prolonged retreat, not much secretarial work to do; but he acted as honorary treasurer to the British members of the unit, and, in a thousand ways, he was of service to us all. His hobby, in ordinary life, is to help others; in our field hospital he was, therefore, in his element, helping both the wounded and the staff, with kindly, unostentatious, and unsolicited services. I owe him much, for his loyalty to the command of a woman, was a fine example of unselfishness. The sergeant was not a soldier born; he was, by constitution, weak and lazy, but he meant well. The men had at once summed him up, and they had told me, with charming _naïveté_, after the first few days of our trek, that he had no influence over them, but that they liked him because he was amiable. Sandford and Merton were fish out of water; they were not adaptable, but they were invariably courteous and loyal.
