The topic was again touched upon on March 3, in a question put by Captain Faber, to which Mr. Haldane replied.
Sir,—The question raised last night by Mr. Arnold-Forster is one which calls for more careful consideration than it appears yet to have received. International law has in modern times spoken with no very certain voice as to the permissible treatment of alien enemies found within the territory of a belligerent at the outbreak of war.
There is, however, little doubt that such persons, although now more usually allowed to remain, during good behaviour, may be expelled, and, if necessary, wholesale, as were Germans from France in 1870. But may such persons be, for good reasons, arrested, or otherwise prevented from leaving the country, as Germans were prevented from leaving France in the earlier days of the Franco-Prussian War? Grotius speaks with approval of such a step being taken, "ad minuendas hostium vires." Bynkershoek, more than a century later, recognises the right of thus acting, "though it is rarely exercised." So the Supreme Court of the United States in Brown v. United States (1814). So Chancellor Kent (1826), and Mr. Manning (1889) is explicit that the arrest in question is lawful, and that "the individuals are prisoners of war."
[046]Vattel, is it true (1758), ventures to lay down that—
"Le Souverain qui déclare la guerre ne peut retenir les sujets de ennemi qui se trouvent dans ses états au moment de la déclaration ... en leur permettant d'entrer dans ses terres et d'y séjourner, il leur a promis tacitement toute liberté et toute sûreté pour le retour."
And he has been followed by some recent writers. There is, however, I venture to hold, no ground for asserting that this indulgent system is imposed by international law. I am glad, therefore, to find the Attorney-General laying down that—
"for strictly military reasons, any nation is entitled to detain and to intern soldiers found upon the territory at the outbreak of war."
And I should be surprised if, under all circumstances, as the learned Attorney-General seems to think probable—
"England would follow, whatever the strict law may be, the humane and chivalrous practice of modern times, and would give to any subjects of a hostile Power who might be found here engaging in civilian pursuits a reasonable time within which to leave for their own country, even although they were under the obligation of entering for service under the enemy's flag."
