Yellow fever also broke out in the rear, chiefly among the Cubans. It never became epidemic, but it caused a perfect panic among some of our own doctors, and especially in the minds of one or two generals and of the home authorities. We found that whenever we sent a man to the rear he was decreed to have yellow fever, whereas, if we kept him at the front, it always turned out that he had malarial fever, and after a few days he was back at work again. I doubt if there were ever more than a dozen genuine cases of yellow fever in the whole cavalry division; but the authorities at Washington, misled by the reports they received from one or two of their military and medical advisers at the front, became panic-struck, and under the influence of their fears hesitated to bring the army home, lest it might import yellow fever into the United States. Their panic was absolutely groundless, as shown by the fact that when brought home not a single case of yellow fever developed upon American soil. Our real foe was not the yellow fever at all, but malarial fever, which was not infectious, but which was certain, if the troops were left throughout the summer in Cuba, to destroy them, either killing them outright, or weakening them so that they would have fallen victims to any disease that attacked them. However, for a time our prospects were gloomy, as the Washington authorities seemed determined that we should stay in Cuba. They unfortunately knew nothing of the country nor of the circumstances of the army, and the plans that were from time to time formulated in the Department (and even by an occasional general or surgeon at the front) for the management of the army would have been comic if they had not possessed such tragic possibilities. Thus, at one period it was proposed that we should shift camp every two or three days. Now, our transportation, as I have pointed out before, was utterly inadequate. In theory, under the regulations of the War Department, each regiment should have had at least twenty-five wagons. As a matter of fact our regiment often had none, sometimes one, rarely two, and never three; yet it was better off than any other in the cavalry division. In consequence it was impossible to carry much of anything save what the men had on their backs, and half of the men were too weak to walk three miles with their packs. Whenever we shifted camp the exertion among the half-sick caused our sick-roll to double next morning, and it took at least three days, even when the shift was for but a short distance, before we were able to bring up the officers' luggage, the hospital spare food, the ammunition, etc. Meanwhile the officers slept wherever they could, and those men who had not been able to carry their own bedding, slept as the officers did. In the weak condition of the men the labor of pitching camp was severe and told heavily upon them. In short, the scheme of continually shifting camp was impossible of fulfilment.
