INSTRUCTIONS FOR THE GOVERNMENT OF ARMIES
OF THE UNITED STATES IN THE FIELD.
SECTION I.–Martial law–Military jurisdiction–Military necessity–Retaliation.
1. A place, district, or country occupied by an enemy stands, in consequence of the occupation, under the martial law of the invading or occupying army, whether any proclamation declaring martial law, or any public warning to the inhabitants, has been issued or not. Martial law is the immediate and direct effect and consequence of occupation or conquest.
The presence of a hostile army proclaims its martial law.
2. Martial law does not cease during the hostile occupation, except by special proclamation, ordered by the commander-in-chief, or by special mention in the treaty of peace concluding the war, when the occupation of a place or territory continues beyond the conclusion of peace as one of the conditions of the same.
3. Martial law in a hostile country consists in the suspension by the occupying military authority of the criminal and civil law, and of the domestic administration and government in the occupied place or territory, and in the substitution of military rule and force for the same, as well as in the dictation of general laws, as far as military necessity requires this suspension, substitution, or dictation.
The commander of the forces may proclaim that the administration of all civil and penal law shall continue either wholly or in part, as in times of peace, unless otherwise ordered by the military authority.
4. Martial law is simply military authority exercised in accordance with the laws and usages of war. Military oppression is not martial law; it is the abuse of the power which that law confers. As martial law is executed by military force, it is incumbent upon those who administer it to be strictly guided by the principles of justice, honor, and humanity–virtues adorning a soldier even more than other men, for the very reason that he possesses the power of his arms against the unarmed.
5. Martial law should be less stringent in places and countries fully occupied and fairly conquered. Much greater severity may be exercised in places or regions where actual hostilities exist or are expected and must be prepared for. Its most complete sway is allowed–even in the commander’s own country–when face to face with the enemy, because of the absolute necessities of the case, and of the paramount duty to defend the country against invasion.
To save the country is paramount to all other considerations.
6. All civil and penal law shall continue to take its usual course in the enemy’s places and territories under martial law, unless interrupted or stopped by order of the occupying military power; but all the functions of the hostile government–legislative, executive, or administrative–whether of a general, provincial, or local character, cease under martial law, or continue only with the sanction, or, if deemed necessary, the participation of the occupier or invader.
7. Martial law extends to property, and to persons, whether they are subjects of the enemy or aliens to that government.
8 Consuls, among American and European nations, are not diplomatic agents. Nevertheless, their offices and persons will be subjected to martial law in cases of urgent necessity only; their property and business are not exempted. Any delinquency they commit against the established military rule may be punished as in the case of any other inhabitant, and such punishment furnishes no reasonable ground for international complaint.
9. The functions of ambassadors, ministers, or other diplomatic agents, accredited by neutral powers to the hostile government, cease, so far as regards the displaced government; but the conquering or occupying power usually recognizes them as temporarily accredited to itself.
10. Martial law affects chiefly the police and collection of public revenue and taxes, whether imposed by the expelled government or by the invader, and refers mainly to the support and efficiency of the Army, its safety, and the safety of its operations.
11. The law of war does not only disclaim all cruelty and bad faith concerning engagements concluded with the enemy during the war, but also the breaking of stipulations solemnly contracted by the belligerents in time of peace, and avowedly intended to remain in force in case of war between the contracting powers.
It disclaims all extortions and other transactions for individual gain; all acts of private revenge, or connivance at such acts.
Offenses to the contrary shall be severely punished, and especially so if committed by officers.
12. Whenever feasible, martial law is carried out in cases of individual offenders by military courts; but sentences of death shall be executed only with the approval of the chief executive, provided the urgency of the case does not require a speedier execution, and then only with the approval of the chief commander.
13. Military jurisdiction is of two kinds: First, that which is conferred and defined by statute; second, that which is derived from the common law of war. Military offenses under the statute law must be tried in the manner therein directed; but military offenses which do not come within the statute must be tried and punished under the common law of war. The character of the courts which exercise these jurisdictions depends upon the local laws of each particular country.
In the armies of the United States the first is exercised by courts-martial; while cases which do not come within the Rules and Articles of War, or the jurisdiction conferred by statute on courts-martial, are tried by military commissions.
14. Military necessity, as understood by modern civilized nations, consists in the necessity of those measures which are indispensable for securing the ends of the war, and which are lawful according to the modern law and usages of war.
15. Military necessity admits of all direct destruction of life or limb of armed enemies, and of other persons whose destruction is incidentally unavoidable in the armed contests of the war; it allows of the capturing of every armed enemy, and every enemy of importance to the hostile government, or of peculiar danger to the captor; it allows of all destruction of property, and obstruction of the ways and channels of traffic, travel, or communication, and of all withholding of sustenance or means of life from the enemy; of the appropriation of whatever an enemy’s country affords necessary for the subsistence and safety of the Army, and of such deception as does not involve the breaking of good faith either positively pledged, regarding agreements entered into during the war, or supposed by the modern law of war to exist. Men who take up arms against one another in public war do not cease on this account to be moral beings, responsible to one another and to God.
16. Military necessity does not admit of cruelty–that is, the infliction of suffering for the sake of suffering or for revenge, nor of maiming or wounding except in fight, nor of torture to extort confessions. It does not admit of the use of poison in any way, nor of the wanton devastation of a district. It admits of deception, but disclaims acts of perfidy; and, in general, military necessity does not include any act of hostility which makes the return to peace unnecessarily difficult.
17. War is not carried on by arms alone. It is lawful to starve the hostile belligerent, armed or unarmed, so that it leads to the speedier subjection of the enemy.
18. When a commander of a besieged place expels the non-combatants, in order to lessen the number of those who consume his stock of provisions, it is lawful, though an extreme measure, to drive them back, so as to hasten on the surrender.
19. Commanders, whenever admissible, inform the enemy of their intention to bombard a place, so that the non-combatants, and especially the women and children, may be removed before the bombardment commences. But it is no
infraction of the common law of war to omit thus to inform the enemy. Surprise may be a necessity.
20. Public war is a state of armed hostility between sovereign nations or governments. It is a law and requisite of civilized existence that men live in political, continuous societies, forming organized units, called states or nations, whose constituents bear, enjoy, and suffer, advance and retrograde together, in peace and in war.
21. The citizen or native of a hostile country is thus an enemy, as one of the constituents of the hostile state or nation, and as such is subjected to the hardships of the war.
22. Nevertheless, as civilization has advanced during the last centuries, so has likewise steadily advanced, especially in war on land, the distinction between the private individual belonging to a hostile country and the hostile country itself, with its men in arms. The principle has been more and more acknowledged that the unarmed citizen is to be spared in person, property, and honor as much as the exigencies of war will admit.
23. Private citizens are no longer murdered, enslaved, or carried off to distant parts, and the inoffensive individual is as little disturbed in his private relations as the commander of the hostile troops can afford to grant in the overruling demands of a vigorous war.
24. The almost universal rule in remote times was, and continues to be with barbarous armies, that the private individual of the hostile country is destined to suffer every privation of liberty and protection and every disruption of family ties. Protection was, and still is with uncivilized people, the exception.
25. In modern regular wars of the Europeans and their descendants in other portions of the globe, protection of the inoffensive citizen of the hostile country is the rule; privation and disturbance of private relations are the exceptions.
26. Commanding generals may cause the magistrates and civil officers of the hostile country to take the oath of temporary allegiance or an oath of fidelity to their own victorious government or rulers, and they may expel every one who declines to do so. But whether they do so or not, the people and their civil officers owe strict obedience to them as long as they hold sway over the district or country, at the peril of their lives.
27. The law of war can no more wholly dispense with retaliation than can the law of nations, of which it is a branch. Yet civilized nations acknowledge retaliation as the sternest feature of war. A reckless enemy often leaves to his opponent no other means of securing himself against the repetition of barbarous outrage.
28. Retaliation will therefore never be resorted to as a measure of mere revenge, but only as a means of protective retribution, and moreover cautiously and unavoidably–that is to say, retaliation shall only be resorted to after careful inquiry into the real occurrence and the character of the misdeeds that may demand retribution.
Unjust or inconsiderate retaliation removes the belligerents farther and farther from the mitigating rules of regular war, and by rapid steps leads them nearer to the internecine wars of savages.
29. Modern times are distinguished from earlier ages by the existence at one and the same time of many nations and great governments related to one another in close intercourse.
Peace is their normal condition; war is the exception. The ultimate object of all modern war is a renewed state of peace.
The more vigorously wars are pursued the better it is for humanity. Sharp wars are brief.
30. Ever since the formation and coexistence of modern nations, and ever since wars have become great national wars, war has come to be acknowledged not to be its own end, but the means to obtain great ends of state, or to consist in defense against wrong; and no conventional restriction of the modes adopted to injure the enemy is any longer admitted; but the law of war imposes many limitations and restrictions on principles of justice, faith, and honor.
