Chapter V — 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.
