When, in 1914, the Great War broke upon an astonished world, we rather took comfort to ourselves in the thought that no matter how swiftly and vigorously military operations might be prosecuted, the Conventions of Geneva and of The Hague would insure humane care and chivalrous treatment to the prisoners of war of both sides. Perhaps unconsciously we based our feeling of assurance in this regard upon two assumptions. The first of these was that the terms of those conventions were of themselves legally binding upon the parties to the great conflict; and the second that in this day and generation of high development in the elements of morality and humanity the belligerents would feel themselves morally if not technically constrained to abide by the principles, and to follow, in practice, the honorable provisions of the conventions.
There are two particular conventions falling under consideration in this connection. These are, the Convention Respecting the Laws and Customs of War on Land, generally referred to as Hague IV of 1907; and the Convention for the Adaptation to Maritime War of the Principles of the Geneva Convention of 1906, commonly known as Hague X of 1907. Each of these agreements contains a provisional article, practically identical in the two instances, worded substantially as follows:
The provisions contained … in the present convention do not apply except between contracting parties, and only if all the belligerents are parties to the convention.
