In 1881–2, during discussions of a committee of the Board of Trade, which was considering the question of a tunnel under the English Channel, the following question was asked: “Is it possible that war would be declared against us, as we might say out of a clear sky, without any previous strain or notice that a quarrel was impending?” To answer this question, the Adjutant-General ordered a special investigation concerning the extent to which wars had been made without previous declaration. The report, when completed, evidenced the surprise of the author at the great number of undeclared wars, and incidentally remarked:
The most excellent general impressions as to what ought to be the mode of procedure by which statesmen give warning before they make war, will not be an adequate security for the freedom of a kingdom, if it is in fact true that under the excitement of popular passion or private ambition, rulers of armies or of armed nations have sometimes disregarded all obligations of the kind, and have, in the midst of profound peace, taken advantage of the confidence of their neighbors.

Wilson, in this JOURNAL, Vol. 26 (1932), p. 327: “Under this convention there might be a state of war in the legal sense after declaration even though there might be no use of force upon the part of either state.” Of the termination of the World War he says: “There existed accordingly for the United States a legal state of war for a considerable period after the use of force had ceased…. There may, therefore, be a state of war without the use of force or after the use of force has ceased, or there may be the use of force without a state of war.”Google Scholar

16 Of one such episode Maurice says that even the astute Lord Palmerston was deceived, though “it is abundantly clear that if ever the withdrawal of an ambassador was used as the modern equivalent of a declaration of war, or warning of war to be followed by acts of hostility without further notice, that withdrawal of the French Ambassador was so regarded by the withdrawing Cabinet, and so understood by the French Senate and House of Representatives to which it was announced.” Ibid.
A British court, called to pass upon the beginning of the Franco–Prussian War, said: “Their Lordships do not think that either the declaration made by the French Minister to the French Chambers on the 16th of July, or the telegram sent by Count Bismarck to the Prussian Ambassador in London, in which he states that that declaration appears to be equal to a declaration of War, amounts to an actual declaration of War.” And, though war can exist without declaration, yet “this can only be effected by an actual commencement of hostilities.” The Teutonic, VIII Moore N.S. 411, 17 Beprint 366 (1872).

21 “But whenever men are formed into a social body, war cannot exist between individuals. The use of force among them is not war, but a trespass, cognizable by municipal law.” U. S. v. The Active, 24 Fed. Cas. 755, No. 14, 420 (1814).

23 “From these principles it necessarily follows that in the absence of recognition by any government of their belligerent rights, insurgents that send out vessels of war are, in legal contemplation, merely combinations of private persons engaged in unlawful depredations on the high seas; that they are civilly and criminally responsible in the tribunals for all their act of violence; … that such acts are therefore piratical …” The Ambrose Light, 25 Fed. 408 (1885).

He adds, in a footnote, that the Permanent Court of International Justice (Series A, No. 7, p. 28), declared that this recognition could not “be relied on as against Germany, which had no share in the transaction.”

26 We are speaking in terms of customary international law. Where states have agreed by treaty, as under the Covenant of the League of Nations, to permit other states to determine the existence of war, the situation is of course different.

43 Janson v. Driefontein Consolidated Mines, L. R. [1902] A. C. 484,509. In this case Lord Brampton said: “it would indeed be strange that a declaration of war should be held to have relation back to an indefinite period of time during which both the hostile countries believed themselves to be and conducted themselves towards each other as in a condition of amity, and were negotiating with a view to avoid any rupture of a then existing state of peace.” Ibid., p. 503.
44 More care as to timing came to be shown during the World War. Thus China, in her declaration against Germany, fixed the time at 10 a.m. on Aug. 14; France against Austria– Hungary on Aug. 12 at midnight; etc. Naval War College, op. cit., p. 74, and passim.

45 Naval War College, op. cit., pp. 226–226. By subsequent act of Congress (Oct. 6,1917) the beginning of war was fixed at “midnight ending the day on which Congress has declared or shall declare war or the existence of a state of war.” This, however, seems inconsistent with the declaration, which affirms that Germany had already thrust a state of war upon the United States.
