The shipping of horses is especially difficult. By former methods the horses had to stand the entire trip and had practically no exercise. This left them in a weakened condition and made necessary a long rest after arrival. For a war transport, in which is required a rapid and successful offensive, such horses are not useful. Because of the important work to be done by them after landing, careful attention should be given to the horses to keep them in good working condition. To this end, proper nourishment must be given and facilities provided for daily exercise while on the transports, which should consume at least three-quarters of an hour for each horse.
Ships that are built particularly for the transportation of horses can be adjusted with four decks over each other, including upper deck stables and two courses for exercise, so that a transport of from three to four thousand net tons capacity can carry over one thousand horses. Three ships would accommodate two cavalry brigades. On every large steamer many horses can be shipped for a long trip, in addition to its regular quota of men and supplies.
After the transports have been prepared, about seven hundred and fifty horses, equal to one cavalry regiment, or six batteries, can be loaded daily on the lower decks. Cleanliness, ventilation and care are the three most important factors for the good health of the horses. Every horse transport must be given ventilating apparatus to assure sufficient fresh air. Artificial ventilation is to be preferred to natural ventilation, for if the latter becomes too strong the horses' lungs are easily affected. Through this cause, for example, the American transport to Cuba lost the greater number of their horses.
Likewise condensers are required for the necessary quantities of drinking water. It is recommended that each ship be given its own condenser. The provision of only one or two large condensers on special ships which supply the entire demand of the transport fleet, as the Americans employed in their expedition to Cuba, has not proved practical.
For the short sea voyage, our transports would be able to despatch substantially more troops, through Germany's geographical position. The strength of near-by powers requires, though, the immediate utilization of all ships and materials at our disposal, if the operations are to succeed. For short expeditions, the general rule will be to ship as many troops as the transports will carry. The forces will bivouac on the upper and lower decks and receive only straw bags and covers. They will keep their whole baggage with them. Cooking will be done in large field kettles. If time permits, it is recommended that the same adjustments as for a long journey be made for the horses, at least to provide separate stalls. This will prevent heavy losses in case of rough weather. Guns and accessories can be disposed of in the same manner as for long voyages.
The length of time for embarkation depends on whether the loading can be done from the wharves of the harbors or whether the troops and materials must be taken out by lighters and then transferred to the ships. The latter method is a waste of time and is dependent on wind and weather.
The time required for loading is as follows: Fifteen minutes for one hundred men, one minute for one horse, ten minutes for a cannon. In an operation by the Russians, 8,000 men, including infantry and cavalry, were embarked in eight hours. In our loading of East Asia transports, it required one to one and one-half hours to load one battalion. The speed of our loading has amazed departmental circles in general. It is certain, though, that this time can be greatly reduced through detailed preparation and training. Napoleon I, in the year 1795, had ostensibly drilled his troops so well that he could plan to put 132,000 men and their materials on shipboard in two hours.
It must be remembered that everything, troops, guns and supplies must eventually be landed on open coasts. Portable flat-bottom boats and building materials for piers must therefore be carried on the transports. Special vessels must accompany the transport fleet with large reserve supplies of food, equipment, ammunition, coal and so forth. A cable-laying ship is also required.
We must now consider to what extent Germany is able to load forces for the execution of operations which involve only a short voyage, in which success depends so much on speed. For embarkation on the North Sea, Hamburg and Bremen alone could furnish so many steamers capable of being converted into transports, that with their tonnage capacity the loading of four infantry divisions is possible in a period of four days. With the addition of ships from Emden, Wilhelmshaven, Glückstadt and Kiel we would be able to despatch in the same length of time, at least six infantry divisions, or five infantry and one cavalry division. To these must be added several especially large and fast German steamers, partly for the shipment that might be delayed and partly to expedite the return to home waters. A large number of troops can also be shipped from Baltic ports. Besides this, a repeated trip of the transport fleet is possible if the command of the sea is maintained continuously.
For longer sea voyages, in which the importance of speed is not so great, our transport fleet can be greatly increased through chartering or purchasing ships of foreign nations. Still, we are at present in the position to despatch about four infantry divisions, with present available ships, within ten or twelve days.
