CHAPTER V. The Commencement of War

THE COMMENCEMENT OF WAR

SECTION 1

Declaration of War

The following letter bears upon the question, much discussed in recent years, of the lawfulness of hostilities commenced without anything amounting to a declaration of war. Although several modern wars, e.g. the Franco-Prussian of 1870, and the Russo-Turkish of 1877, were preceded by declaration, it was hardly possible, in view of the practice of the last two centuries, to maintain, that this was required by international law, and it has never been alleged that any definite interval need intervene between a declaration and the first act of hostilities. On the destruction of the Kowshing, the present writer may further refer to his Studies in International Law, 1898, p. 126, and to Professor Takahashi's International Law during the Chino-Japanese War, 1899, pp. 24, 192. But see now the note at the end of the "Letter" which follows.

THE SINKING OF THE KOWSHING

Sir,--The words of soberness and truth were spoken with reference to the sinking of the Kowshing in the letter from Professor Westlake which you printed on Friday last. Ignorance dies hard, or, after the appearance of that letter and of your remarks upon it, one might have expected that leading articles would be less lavishly garnished with such phrases as "act of piracy," "war without declaration," "insult to the British flag," "condign punishment of the Japanese commander." But these flowers of speech continue to blossom; and, now that the facts of the case seem to be established beyond reasonable doubt by the telegrams of this morning, I should be glad to be allowed to state shortly what I believe will be the verdict of international law upon what has occurred.

If the visiting, and eventual sinking, of the Kowshing occurred in time of peace, or in time of war before she had notice that war had broken out, a gross outrage has taken place. But the facts are otherwise.

In the first place, a state of war existed. It is trite knowledge, and has been over and over affirmed by Courts, both English and American, that a war may legally commence with a hostile act on one side, not preceded by declaration. How frequently this has occurred in practice may be seen from a glance at an historical statement prepared for the War Office by Colonel Maurice à propos of the objections to a Channel tunnel. Whether or no hostilities had previously occurred upon the mainland, I hold that the acts of the Japanese commander in boarding the Kowshing and threatening her with violence in case of disobedience to his orders were acts of war.

In the second place, the Kowshing had notice of the existence of a war, at any rate from the moment when she received the orders of the Japanese commander.

The Kowshing, therefore, before the first torpedo was fired, was, and knew that she was, a neutral ship engaged in the transport service of a belligerent. (Her flying the British flag, whether as a ruse de guerre or otherwise, is wholly immaterial.) Her liabilities, as such ship, were twofold:--

1. Regarded as an isolated vessel, she was liable to be stopped, visited, and taken in for adjudication by a Japanese Prize Court. If, as was the fact, it was practically impossible for a Japanese prize crew to be placed on board of her, the Japanese commander was within his rights, in using any amount of force necessary to compel her to obey his orders.

2. As one of a fleet of transports and men-of-war engaged in carrying reinforcements to the Chinese troops on the mainland, the Kowshing was clearly part of a hostile expedition, or one which might be treated as hostile, which the Japanese were entitled, by the use of all needful force, to prevent from reaching its destination.

The force employed seems not to have been in excess of what might lawfully be used, either for the arrest of an enemy's neutral transport or for barring the progress of a hostile expedition. The rescued officers also having been set at liberty in due course, I am unable to see that any violation of the rights of neutrals has occurred. No apology is due to our Government, nor have the owners of the Kowshing, or the relatives of any of her European officers who may have been lost, any claim for compensation. I have said nothing about the violation by the Japanese of the usages of civilised warfare (not of the Geneva Convention, which has no bearing upon the question), which would be involved by their having fired upon the Chinese troops in the water; not only because the evidence upon this point is as yet insufficient, but also because the grievance, if established, would affect only the rights of the Belligerents inter se; not the rights of neutrals, with which alone this letter is concerned. I have also confined my observations to the legal aspects of the question, leaving to others to test the conduct of the Japanese commander by the rules of chivalrous dealing or of humanity.

Your obedient servant, T. E. HOLLAND. Athenæum Club, August 6 (1894)

The controversy caused by the sinking of the Kowshing in 1894 was revived by the manner of the Japanese attack upon Port Arthur, in 1904 (see Professor Takahashi's International Law applied to the Russo-Japanese War, 1908, p. 1), and led to a careful study of the subject by a committee of the Institut de Droit International, resulting in the adoption by the Institut, at its Ghent Meeting in 1906, of the following resolutions:--

(1) "It is in conformity with the requirements of International law, to the loyalty which the nations owe to one another in their, mutual relations, as well as to the general interests of all States, that hostilities ought not to commence without previous and unequivocal warning.

(2) "This warning may be given either in the shape of a declaration of war pure and simple, or in the shape of an ultimatum duly notified to the adversary by the State which wishes to begin the war.

(3) "Hostilities must not commence until after the expiration of a delay which would suffice to prevent the rule as to a previous and unequivocal warning from being thought to be evaded." See the Annuaire de l'Institut, t, xxi. p. 292.

In accordance with the principles underlying the first and second of these resolutions, The Hague Convention, No. iii. of 1907 (ratified generally by Great Britain on November 27, 1909), has now laid down as a principle of International Law, binding upon the contracting Powers, that--

(1) "Hostilities between them ought not to commence without a warning previously given and unequivocal, in the form either of a reasoned declaration of war, or of an ultimatum, with a conditional declaration of war."

And the Convention goes on to provide that--

(2) "The state of war ought to be notified without delay to neutral Powers, and shall be of no effect with reference to them, until after a notification, which may be made even telegraphically. Nevertheless, neutral Powers may not plead absence of notification, if it has been shown beyond question that they were in fact cognisant of the state of war." Any reference to the need of an interval between declaration and the first act of hostility (such as is contained in the third of the resolutions of the Institut) was deliberately omitted from the Convention, although a declaration immediately followed by an attack would obviously be of little service to the party attacked. (See the present writer's Laws of War on Land (written and unwritten), 1908, P. 18.)
