To the army in the field the innovation meant that with the speedy removal of the sick and wounded it would be relieved of the great source of embarrassment caused by the presence and dependence upon it of so many inefficients;[16] depôt and intermediate hospitals could be reduced to the smallest proportions, and would thus occasion less inconvenience if, owing to a retreat or a change in the strategical position, they were brought within the sphere of military operations; with the delegation of so many of the sick and wounded to the care of civil practitioners in the interior, fewer of the divisional, brigade and regimental medical officers would require to be detached from the marching column; a smaller supplementary medical staff would suffice; a considerable reduction could be effected in the stocks of ambulance supplies kept on hand at the front; while important strategical advantages would be gained through (1) the greater freedom of movement which the army would secure; (2) the decreased risk of the number of efficients being reduced through the outbreak of epidemics; and (3) the prospect of a large proportion of the sick and wounded being enabled to rejoin the fighting force on their making a speedy recovery from their illness or their wounds.

The earliest occasion on which the railway was made use of for the conveyance of sick and wounded from a scene of actual hostilities to the rear was on the occasion of the Crimean War, when the little military line between Balaklava and the camp before Sebastopol, of which an account will be given in Chapter XV, was so employed. The facilities afforded were, however, of the most primitive character. Only the wagons used for the transport of supplies to the front—wagons, that is to say, little better than those known as "contractors' trucks"—were available, and there were no means of adapting them to the conveyance of sufferers who could not be moved otherwise than in a recumbent position. Sitting-up cases could, therefore, alone be carried; but what was to develop into a revolution in the conditions of warfare was thus introduced, all the same.

In the Italian war of 1859 both the French and the Austrians made use of the railways for the withdrawal of their sick and wounded, and, in his "Souvenir de Solferino," Jean Henri Dumant, the "Father" of the Red Cross Movement, speaks of the transportation of wounded from Brescia to Milan by train to the extent of about 1,000 a night. No arrangements for their comfort on the journey had been made in advance, and the changes in the military situation were so rapid, when hostilities broke out, that no special facilities could be provided then. All that was done was to lay down straw on the floor of the goods or cattle trucks used for the conveyance of some of the more serious cases. The remainder travelled in ordinary third-class carriages, and their sufferings on the journey, before they reached the long and narrow sheds put up along the railway lines at Milan or elsewhere to serve as temporary hospitals, must often have been very great. They may, nevertheless, have escaped the fate of those who died, not from their wounds, but from the fevers quickly generated in the overcrowded hospitals at the front, where there was, besides, a general deficiency of ambulance requirements of all kinds. The good resulting from the removal by train is, indeed, said to have been "immense."

These experiences in the campaign of 1859 led to a recommendation being made in the following year by a German medical authority, Dr. E. Gurlt,[17] that railway vehicles should be specially prepared for the conveyance of the sick and wounded in time of war. The plan which he himself suggested for adoption was the placing of the sufferers in hammocks suspended from hooks driven into the roof of the goods van or carriage employed, mattresses being first put on the hammocks, when necessary. By this means, he suggested, the sufferers would travel much more comfortably than when seated in the ordinary passenger carriages, or when lying on straw in the goods wagons or cattle trucks.

Dr. Gurlt's pamphlet served the good purpose of drawing much attention to the subject, and his proposals were duly subjected to the test of experiment. They failed, however, on two grounds,—(1) because the roofs of the goods vans, designed for shelter only, were not sufficiently strong to bear the weight of a number of men carried in the way suggested; and (2) because the motion of the train caused the hammocks to come into frequent contact with the sides of the wagon, to the serious discomfort of the occupants.

In November of the same year (1860) the Prussian War Minister, von Roon, appointed a Commission to enquire into the whole subject of the care of the sick and wounded in time of war, and the question of transport by rail was among the various matters considered. As a result of these investigations, the Minister issued, on July 1, 1861, an order to the effect that in future the less seriously wounded should travel in ordinary first, second or third-class carriages, according to the degree of comfort they required, care being taken to let them have corner seats; while for those who were seriously ill, or badly wounded, there were to be provided sacks of straw having three canvas loops on each side for the insertion of poles by means of which the sacks and the sufferers lying upon them could be readily lifted in or out of the goods wagons set apart for their conveyance. In these wagons they were to be placed on the floor in such a way that each wagon would accommodate either seven or eight. In the event of a deficiency of sacks, loose straw was to be used instead. The door on one side of the truck was to be left open for ventilation. A doctor and attendants were to accompany each train, and they were to have a supply of bandages, medicines and appliances. Of the last-mentioned a list of five articles was appended as obligatory. The medical officer was to visit the wagons during the stoppages, and the attendants on duty in the wagons were to carry flags so that, when necessary, they could signal both for the train to pull up and for the doctor to come to the sufferers.

This was as far as Prussia had got by 1861, when the arrangements stated were regarded as quite sufficient to meet the requirements of the situation. Real progress was to come, rather, from the other side of the Atlantic.

In the early days of the War of Secession (1861-65) the arrangements for the conveyance by rail of the sick and wounded from the battle-fields of the Eastern States to the hospitals in the large cities were still distinctly primitive. Those who could sit up in the ordinary cars were conveyed in them. Those who could not sit up, or would be injured by so doing, were carried to the railway, by hand, on the mattresses or stretchers they had occupied in the hospitals to which they had first been taken. At the station the mattresses were placed on thick layers of straw or hay strewn over the floors of the freight cars in which supplies had been brought to the front. Large window spaces were cut in the sides or ends of the cars to provide for ventilation. On some occasions, when hay or straw was not available, pine boughs or leaves were used instead. As only the floor space was occupied no more than about ten patients could be carried comfortably in each car, though as many as twenty were occasionally crowded in. The wide doors of the box cars readily permitted of the beds being lifted in or out. Medical officers, with supplies, accompanied each train. On arrival at New York, Washington, Philadelphia, Harrisburg, or other destination, the sufferers were taken out and carried, still on the same mattresses or stretchers, to the hospitals there.
