Although it is generally recognised that a belligerent acts lawfully who makes use of the offer of a traitor, the question is controversial[314] whether a belligerent acts lawfully who bribes a commander of an enemy fortress into surrender, incites enemy soldiers to desertion, bribes enemy officers for the purpose of getting important information, incites enemy subjects to rise against the legitimate Government, and the like. If the rules of the Law of Nations are formulated, not from doctrines of book-writers, but from what is done by the belligerents in practice,[315] it must be asserted that such acts, detestable and immoral as they are, are not considered illegal according to the Law of Nations.

Character of Ruses of War.

§ 163. Ruses of war or stratagems are deceit employed during military operations for the purpose of misleading the enemy. Such deceit is of great importance in war, and, just as belligerents are allowed to employ all methods of obtaining information, so they are, on the other hand, and article 24 of the Hague Regulations confirms this, allowed to employ all sorts of ruses for the purpose of deceiving the enemy. Very important objects can be attained through ruses of war, as, for instance, the surrender of a force or of a fortress, the evacuation of territory held by the enemy, the withdrawal from a siege, the abandonment of an intended attack, and the like. But ruses of war are also employed, and are very often the decisive factor, during battles.

Different kinds of Stratagems.

§ 164. Of ruses there are so many kinds that it is impossible to enumerate[316] and classify them. But in order to illustrate acts carried out as ruses some instances may be given. It is hardly necessary to mention the laying of ambushes and traps, the masking of military operations such as marches or the erection of batteries and the like, the feigning of attacks or flights or withdrawals, the carrying out of a surprise, and other stratagems employed every day in war. But it is important to know that, when useful, feigned signals and bugle-calls may be ordered, the watchword of the enemy may be used, deceitful intelligence may be disseminated,[317] the signals and the bugle-calls of the enemy may be mimicked[318] to mislead his forces. And even such detestable acts[319] as bribery of enemy commanders and officials in high position, and secret seduction of enemy soldiers to desertion, and of enemy subjects to insurrection, are frequently committed, although many writers protest. As regards the use of the national flag, the military ensigns, and the uniforms of the enemy, theory and practice are unanimous in rejecting it during actual attack and defence, since the principle is considered inviolable that during actual fighting belligerent forces ought to be certain who is friend and who is foe. But many[320] publicists maintain that until the actual fighting begins belligerent forces may by way of stratagem make use of the national flag, military ensigns, and uniforms of the enemy. Article 23 (f) of the Hague Regulations does not prohibit any and every use of these symbols, but only their improper use, thus leaving the question open,[321] what uses are proper and what are not. Those who have hitherto taught the admissibility of the use of these symbols outside actual fighting can correctly maintain that the quoted article 23 (f) does not prohibit it.[322]
