Operations Upon the Sea: A Study

If a landing near a harbor is successful, the advance guard will strive to take the same unawares, to seize those coast sentinels at hand and to destroy the telegraph and signal service along the coast. If all this is successful, the transport fleet will be signaled to draw near. The advantage is apparent in landing in a large harbor or bay, which affords the possibility of protection from a sea attack, through the mining of the waters or through the guard of a limited number of battleships. Earthworks, equipped with cannon and machine guns, must be thrown up for the protection from the land side.

The piers must be distributed to make sufficient room for disembarking. The existing plans for improvising landing bridges and gangways should be extended, in order to expedite the landing. The piers and bridges will be used for ships carrying horses, artillery and heavy materials, while the infantry land by boats, under the protection of large guns on shore or of the escorting battleships, should the battle fleet maintain command of the sea. The landed troops should be supplied provisions for many days so that they can begin operations independent of the supply trains.

The time required for landing is considerably less than for loading. The natural desire of the troops to land quickly helps to shorten the time. One writer gives the following data: Lord Cochran landed 18,000 men on the open coast of America in five hours; in the Crimean War the English accomplished the disembarking of 45,000 men, 83 guns and about 100 horses in less than eleven hours. The French are slower on account of their handling of supply trains. The Russians, in their landing maneuvers in the Black Sea, have landed a slow division in eleven and one-half hours, where the steamers had to anchor five to six kilometers from the coast. The marine writer Degories figures that under average conditions it is possible to land 25,000 infantry, 1,000 cavalry and 60 guns in six hours. If the landing can be made in a harbor, this time can be essentially lessened.

After the disembarking of the expedition, the further task of the transport fleet and its escort of battleships depends on the maritime strength of the country attacked. If the assailant continues in command of the sea, the transport fleet can remain as a floating base for the landed corps and can effect the reenforcement of the expedition. If the assailant is not in command of the sea, then the transport fleet must attempt to evade the operations of the hostile fleet, by an immediate retreat to home waters.

OPERATIONS.

The operations of the landed expedition corps on the whole can be conducted according to the principles set down by the commanders of the troops, but these principles must take into account the particular conditions under which the forces operate. The well-known marine writer, Mahan, emphasizes the fact that a landing operation must be offensive to succeed. Military history shows that after boldly carried out landings at Abukir and Cape Breton, for example, the success of the extensive operations was impaired, almost lost, because of lack of energy and rapidity of execution of offensive movements. The assembled strength must be thrown forward on the line of least resistance. Defensive strategy should be used only when a delay is necessary to receive expected reenforcements. The primary aim of the operations is to dispose of hostile forces, within the shortest possible time and with the least loss to ourselves.

During the progress of the operations the country through which the troops pass can be drawn upon to supplement equipment and supplies, but the speed of the advance and the efficiency of the troops must not be decreased through extended raids. While the distance to the objective of the invasion is generally not great, it should be our endeavor to be independent of our base of supplies. Much progress has been made in the methods of making condensed foods, for man and horse, which will help to solve the problem of provisions. The army of invasion can also take an important site in the hostile country and utilize it as a base of operations. Continuous communication with the home country is therefore not absolutely necessary. In a densely populated and rich country it is easy to secure provisions and supplies. The maintenance of long lines of communications is hazardous in that it requires excessive guard duty. When the battle fleet has gained command of the sea it will be in a position to protect continuously the base on the coast, and would also make it possible for the corps of invasion to select new bases. Sherman's march to Savannah in the Civil War has shown the practicability of this plan. After one objective has been attained, it should be possible for the expedition to reembark to land at some other point on the coast for further operations.

Against the enemy's defenses we must throw our full strength and avoid enterprises that involve a delay or a weakening of our forces. Dearly purchased victories will in the end defeat our own aims.

If the operations of the troops are carried on along the coast, or if the objective of the operations is a harbor or a coast fortification, the battle fleet should act in unison with the land forces. Battleships are superior to the field artillery, as they can be moved at will and so are hard to put out of action. Continuous bombardment from the battleships would prove effective aid for the troops.

It is important, then, that the command of land and naval forces be joined in a commander-in-chief who would direct the field forces as well as the naval forces. Small coast defenses of seaport cities could not for any length of time withstand such a combined attack. It is certain also that present-day coast defenses could not withstand an energetic attack from the land side. They are more vulnerable than inland fortresses because they are open to attack simultaneously from land and water. However, if the battle fleet cannot gain the command of the sea, and must retreat before the opposing forces, the operations of the landed troops must be conducted wholly as a war on land.

REEMBARKATION.

A reembarkation of the expedition corps is possible only when the battle fleet is able to prevent attack from the sea. In the event of defeat on land, reembarkation is not absolutely impossible, for if good order is maintained the improvised defenses of the landing sites, with the help of the fleet, will sufficiently delay the pursuers. If the reembarking must take place from some other point, preparations for its defense must be made in advance. When the reembarkation is done with the aim in view of attacking at another place, the rules as explained in the chapter on "Embarkation" must be adhered to. For such an operation, more time is essential, and pressure of the enemy should not be permitted to interfere with its management.

APPLICATION

I. CONSIDERATION OF LANDING OPERATIONS AGAINST POWERS THAT CAN BE REACHED ONLY BY SEA

The recognized military complication with England and America affords an interesting example on account of the difference in distances in which the transporting of troops takes place, on account of the strength of the sea and land fighting forces of the two opponents, and lastly on account of the difference in the territorial extensions of the aforesaid countries, and on the whole challenges various measures.

A conflict with England must be fixed in the eye of Germany, for the great German struggle for commerce represents to England just as great a danger as the advance of Russia against India. Beginning operations with a naval war with England, we could almost foresee the result.

England has brought about the existence of such a powerful, active navy that we, with the best defenses we have, would hardly be able to win a decisive victory. Only by closing an alliance with Russia would the strength of England be injured indeed, but never by a direct threat from these provinces. But an alliance with France would in fact menace England. The latter, however, through her geographical location and through her large and timely expenditures, which every combined operation demands, could make possible by proper equipment a maritime superiority against this alliance.

England's weakness is in just that which forms our strength, namely, the land army. The English army responds to neither quantity nor quality of its great and powerful position in comparison with the extent of the land; therefore England, from convictions, proceeds so that every invasion of the land can be prevented by the fleet. These convictions are in no way justified, for while England in developing a powerful sea-fighting strength has every day prepared for war, she has not had a view of the consequences of confronting and beating a really weaker sea opponent with its fighting units.

These are the measures which Germany, in case of a threatened war with England, must adopt and practise: Our endeavors must be to engage the fleet, if possible; to throw part of our land forces upon the English coast, so that the conflict on the sea can be carried to the enemy's land, where our troops are already superior in quality to England's, and so that a victory for England's powerful naval strength could have but the smallest influence.

The army fighting strength of England under the commander-in-chief is composed of the army reserve, the militia, the volunteers and the yeomanry. In the event of an unexpected invasion, only the commander-in-chief and army reserve can be considered to any extent, for the militia needs so much time to assemble and equip that they would be in a weak position to assist the commander-in-chief in the first decisive battle. The volunteers and yeomanry cannot in so short a time be trained for war or be mobilized for action. Also their insignificant fighting value must be kept in view, beside which our well-trained troops will not let them seem as menacing opponents.

The English army is formed of three army corps with three divisions to each corps. A third to a half of these corps is comprised of militia, so that either it must be first completed, and then it would be too late for cooperation in the first decisive battle, or it would be so untrained that it really cannot be said to reach the strength of a division. Of two army corps, two divisions and one cavalry brigade are in Ireland, the greater part of which must remain there to prevent the undertaking of a German invasion through Ireland even though it brought about the longed-for freedom.

The preparation for defense should also be considered. This might consist of one army corps with three divisions, or one army corps comprised of two divisions, with perhaps a cavalry brigade made up from three army corps. Whereas the army strength of an English division is about 10,000 men, a German division carries 16,000 men, hence four German divisions and a cavalry division would have a superiority over the English army. But we are in a position to set over in England, in the shortest time, six divisions of infantry, or five divisions of infantry and one cavalry division.

How a well regulated operation against England is to be conducted across the sea, obviously cannot be forecasted here. The passage in moderate weather is a little over thirty hours' ride from our North Sea harbors. The English coast affords extensive stretches of shore which are suitable for landing troops. The land contains such large resources that the invading army can procure a living therefrom. On the other hand, the extent of the island is not so great that the English land defenses could ever succeed in timely destroying a successful invading force.

It is improbable that Germany could carry on for very long a well regulated war necessitating considerable reenforcement of troops. The supplies would have to be furnished for the greater part on land. Maintaining communication with the home country can therefore readily be seen to be of importance.

It is conclusive that the first aim of every operation of invasion in England is their field army, and the second must be London. It is probable that these two objectives would fall together, in that the field army, on account of the small value of the volunteers, is needed for the protection of London fortifications, so as not to leave the metropolis insufficiently defended. Powerful public opinion would demand this for fear that London would fall into the hands of the invaders. But if London is taken by the invading army this would still be only one of the many war ports which must be seized, to secure a base of supplies and for the further operations which have every view to concluding the overthrow of England.

Operations against the United States of North America must be entirely different. With that country, in particular, political friction, manifest in commercial aims, has not been lacking in recent years, and has, until now, been removed chiefly through acquiescence on our part. However, as this submission has its limit, the question arises as to what means we can develop to carry out our purpose with force, in order to combat the encroachment of the United States upon our interests. Our main factor here is our fleet. Our battle fleet has every prospect of victoriously defeating the forces of the United States, widely dispersed over the two oceans. It is certain that after the defeat of the United States fleet, the great extension of unprotected coast line and powerful resources of that country would compel them to make peace.

There is no effective method to force this opponent to relinquish its maritime operations, even though there is only a trifling number of American merchantmen, except the simultaneous blockading with our sea forces of American ports, which can only be taken with heavy losses, while our fleet demonstrated the actual limited worth of the unpacified American colonies.

It must be deemed a possibility that the battle fleet of the United States would not risk an engagement at sea except to avoid a disaster, but would await, in its fortified harbors, a favorable opportunity to strike. It is evident, then, that a naval war against the United States cannot be carried on with success without at the same time inaugurating action on land. Because of the great extensions of the United States it would not be satisfactory for the operation of an invading army to be directed toward conquering the interior of the land. It is almost a certainty, however, that a victorious assault on the Atlantic coast, tying up the importing and exporting business of the whole country, would bring about such an annoying situation that the government would be willing to treat for peace.

If the German invading force were equipped and ready for transporting the moment the battle fleet is despatched, under average conditions these corps can begin operations on American soil within at least four weeks. To what extent we will be able to succeed has already been considered.

The United States at this time is not in a position to oppose our troops with an army of equal rank. Its regular army actually totals 65,000 men, of whom not more than 30,000 are ready to defend the home country. Of these at least 10,000 men are required to guard Indian territory and for the garrisoning of coast-wise fortifications, so that only a regular army of 20,000 is available for field service. There is also a militia of 100,000 men, the larger number of whom have not been trained since the last war summons, and they are poorly equipped with inferior rifles and still more poorly drilled.

If an unexpected invasion of the United States is prevented by the length of time for the transporting of troops, and only an unexpected landing can take place, it must be emphasized that the weakness and inexperience of their regular army would essentially facilitate a quick invasion.

For the continued occupation of as large a territory as the United States, if they can oppose us for any length of time, an important fighting force will be necessary, to protect the operating lines and to carry on a successful warfare. An invading operation will be difficult to reenforce, in that a second trip of the transport fleet will be required, in order to despatch the necessary number of troops, at such a great distance.

It is upon the whole questionable whether there is anything to be gained in occupying for any length of time so large a stretch of land as the United States. The fact that one or two of her provinces are occupied by the invaders would not alone move the Americans to sue for peace. To accomplish this end the invaders would have to inflict real material damage by injuring the whole country through the successful seizure of many of the Atlantic seaports in which the threads of the entire wealth of the nation meet. It should be so managed that a line of land operations would be in close juncture with the fleet, through which we would be in a position to seize, within a short time, many of these important and rich cities, to interrupt their means of supply, disorganize all governmental affairs, assume control of all useful buildings, confiscate all war and transport supplies, and lastly, to impose heavy indemnities. For enterprises of this sort small land forces would answer our purpose, for it would be unwise for the American garrisons to attempt an attack.

Their excellently developed net of railways will enable them to concentrate their troops in a relatively short time at the various recognized landing points on the coast. But there are many other splendid landings, and it appears feasible for the invading corps to conduct its operations on these points with the cooperation of the fleet. The land corps can either advance aggressively against the concentrated opposing forces, or through embarking evade an attack and land at a new place.

As a matter of fact, Germany is the only great power which is in a position to conquer the United States. England could of course carry out a successful attack on the sea, but she would not be prepared to protect her Canadian provinces, with which the Americans could compensate themselves for a total or crushing defeat on the sea. None of the other great powers can provide the necessary transport fleet to attempt an invasion.

II. VIEWS ON COLONIAL EXPEDITIONS

All operations for colonial expeditions can be undertaken successfully because of the small forces necessary to transport over the sea to make war upon a country which does not possess modern equipment and trained troops. Just such an expedition was unostentatiously carried out in China before our own eyes.

The sending of an expedition to East Asia affords an interesting example of what can be done. Without resistance we have set up governments at a distance from the home country. It is possible with the aid of the fleet to secure similar results. However, there are many obstacles to be overcome. It is imperative that in time of peace we should prepare in every possible way for war in foreign lands which have any commercial value for us. Inasmuch as the German army has determined upon larger divisions of troops, the problems of operations on the distant sea falls to the navy. In the future the conducting of such operations will rest with the General Staff. It will be necessary to continue the preparations, described fully in the forepart of this book, for the carrying out of operations against such countries as Asia, Africa and South America. Good judgment must be used in the selection of methods. The execution of the first operations would require the constantly combined efforts of the General Staff and the Admiral Staff.

Our excellent knowledge of East Asia has given us the necessary technical preparation in the way of equipment. The chartering of transport ships for service to China should not be difficult in consequence of the large size of the expedition. The expedition corps would require eighteen ships, material and supplies would take five. The greater part of this number would be amply supplied by our two large steamship companies, the North German Lloyd and the Hamburg-American Line. The charter of these steamship companies provides for their use as transports if needed for expeditions of this sort. The disadvantages of this arrangement once appeared in the delay through a labor strike, when it was necessary to transport part of the unfinished ships to Wilhelmshaven. Another drawback is that not enough room is provided in these ships. On the steamers of the Hamburg-American Line, for example, only sixty-five per cent. of their normal passenger capacity can be utilized for troops which means at the most an approximate displacement of three net tons, so that only one man instead of two can be carried. An adjustment should be reached to the end that the entire freight capacity of the steamers could be counted upon.

The interior arrangements of a steamer to be used for troop transport must be planned according to law. Fire-extinguishers, life-saving apparatus and other necessities must be provided for; numerous tables and benches which can be drawn up to the ceiling should be in the troops rooms, and should also be found up on deck. Hospital arrangements for two and one-half per cent. of the transport strength should be provided.

The active troops of the expedition corps are at present drawn from volunteers, the reserve and the militia, and grouped in new formations. Through this the home defenses may be benefited, but the expedition corps would not be up to standard, even though the newly formed troops would have sufficient time to concentrate. It is advisable for such an expedition to employ active, well-trained soldiers for the main part, while the balance could be made up of reserves. It is also to be recommended that in the near future we form a fixed body of troops trained for hospital service. Such a formation would have great intrinsic worth.

A few words should be said about the organizing of a Colonial army, which would be called upon to play an essential part in German military operations over the sea. It would be of extraordinary value in preserving order in our colonies and would also be of assistance in commercial aims. The Colonial army would constitute a picked body of men, suitable for service in hot climates and uncivilized countries, who would be able to fight effectively against colonies with which we might be at war.

There would still remain, however, the need of preparation of our home forces for colonial expeditions. We are not assured at present of the assembling of the necessary number of qualified troops without drawing on our regular army.

It requires a good deal of time to procure the equipment for an expedition to East Asia. Therefore, contracts with capable firms should be made, to make delivery in the shortest possible time.

While the equipment of the infantry with up-to-date weapons is easily accomplished, it is noteworthy that only about thirty horses can be loaded by the English system. Some effort should be made to solve the horse problem. The purchasing of horses in Australia, America and South China has ceased, in consequence of the knowledge that only a small percentage can withstand the change of climate.

It would be impossible to employ joint cavalry forces, due to lack of mounts. It is imperative to find the means for forming a mounted infantry, for there is an insufficient number of advanced cavalry troops to meet an emergency. It would be advantageous if large brigades now idle could be moved for operations in Eastern China. Past experience in China has emphasized the great importance of cavalry for operations in large countries.
