Prepared by Francis Lieber, promulgated as General Orders No. 100 by

President Lincoln, 24 April 1863.

SECTION I

Martial Law - Military jurisdiction - Military necessity - Retaliation

Article 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.

Art. 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.

Art. 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.

Art. 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.

Art. 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.

Art. 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.

Art. 7. Martial Law extends to property, and to persons, whether they are subjects of the enemy or aliens to that government.

Art. 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.

Art. 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.

Art. 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.

Art. 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.

Art. 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.

Art. 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.

Art. 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.

Art. 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.

Art. 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.

Art. 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.

Art. 18. When a commander of a besieged place expels the noncombatants, 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.

Art. 19. Commanders, whenever admissible, inform the enemy of their intention to bombard a place, so that the noncombatants, 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.

Art. 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, suffer, advance and

retrograde together, in peace and in war.

Art. 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.

Art. 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.

Art. 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.

Art. 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.

Art. 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.

Art. 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 everyone 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.

Art. 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

Art. 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.

Art. 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.

Art. 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.

SECTION II

Public and private property of the enemy - Protection of persons, and

especially of women, of religion, the arts and sciences - Punishment of

crimes against the inhabitants of hostile countries.

Art. 31. A victorious army appropriates all public money, seizes all public movable property until further direction by its government, and sequesters for its own benefit or of that of its government all the revenues of real property belonging to the hostile government or nation. The title to such real property remains in abeyance during military occupation, and until the

conquest is made complete.

Art. 32. A victorious army, by the martial power inherent in the same, may suspend, change, or abolish, as far as the martial power extends, the relations which arise from the services due, according to the existing laws of the invaded country, from one citizen, subject, or native of the same to another.

The commander of the army must leave it to the ultimate treaty of peace to settle the permanency of this change.

Art. 33. It is no longer considered lawful - on the contrary, it is held to be a serious breach of the law of war - to force the subjects of the enemy into the service of the victorious government, except the latter should proclaim, after a fair and complete conquest of the hostile country or

district, that it is resolved to keep the country, district, or place permanently as its own and make it a portion of its own country.

Art. 34. As a general rule, the property belonging to churches, to hospitals, or other establishments of an exclusively charitable character, to establishments of education, or foundations for the promotion of knowledge, whether public schools, universities, academies of learning or observatories, museums of the fine arts, or of a scientific character such property is not to be considered public property in the sense of paragraph 31; but it may be taxed or used when the public service may require it.

Art. 35. Classical works of art, libraries, scientific collections, or precious instruments, such as astronomical telescopes, as well as hospitals, must be secured against all avoidable injury, even when they are contained in fortified places whilst besieged or bombarded.

Art. 36. If such works of art, libraries, collections, or instruments belonging to a hostile nation or government, can be removed without injury, the ruler of the conquering state or nation may order them to be seized and removed for the benefit of the said nation. The ultimate ownership is to be

settled by the ensuing treaty of peace.

In no case shall they be sold or given away, if captured by the armies of the United States, nor shall they ever be privately appropriated, or wantonly destroyed or injured.

Art. 37. The United States acknowledge and protect, in hostile countries occupied by them, religion and morality; strictly private property; the persons of the inhabitants, especially those of women: and the sacredness of domestic relations. Offenses to the contrary shall be rigorously

punished.

This rule does not interfere with the right of the victorious invader to tax the people or their property, to levy forced loans, to billet soldiers, or to appropriate property, especially houses, lands, boats or ships, and churches, for temporary and military uses

Art. 38. Private property, unless forfeited by crimes or by offenses of the owner, can be seized only by way of military necessity, for the support or other benefit of the army or of the United States.

If the owner has not fled, the commanding officer will cause receipts to be given, which may serve the spoliated owner to obtain indemnity.

Art. 39. The salaries of civil officers of the hostile government who remain in the invaded territory, and continue the work of their office, and can continue it according to the circumstances arising out of the war -such as judges, administrative or police officers, officers of city or communal governments - are paid from the public revenue of the invaded territory, until the military government has reason wholly or partially to discontinue it. Salaries or incomes connected with purely honorary titles are always stopped.

Art. 40. There exists no law or body of authoritative rules of action between hostile armies, except that branch of the law of nature and nations which is called the law and usages of war on land.

Art. 41. All municipal law of the ground on which the armies stand, or of the countries to which they belong, is silent and of no effect between armies in the field.

Art. 42. Slavery, complicating and confounding the ideas of property, (that is of a thing,) and of personality, (that is of humanity,) exists according to municipal or local law only. The law of nature and nations has never acknowledged it. The digest of the Roman law enacts the early dictum of the pagan jurist, that "so far as the law of nature is concerned, all men are

equal." Fugitives escaping from a country in which they were slaves, villains, or serfs, into another country, have, for centuries past, been held free and acknowledged free by judicial decisions of European countries, even though the municipal law of the country in which the slave

had taken refuge acknowledged slavery within its own dominions.

Art. 43. Therefore, in a war between the United States and a belligerent which admits of slavery, if a person held in bondage by that belligerent be captured by or come as a fugitive under the protection of the military forces of the United States, such person is immediately entitled to the

rights and privileges of a freeman To return such person into slavery would amount to enslaving a free person, and neither the United States nor any officer under their authority can enslave any human being. Moreover, a person so made free by the law of war is under the shield of the law of

nations, and the former owner or State can have, by the law of postliminy, no belligerent lien or claim of service.

Art. 44. All wanton violence committed against persons in the invaded country, all destruction of property not commanded by the authorized officer, all robbery, all pillage or sacking, even after taking a place by main force, all rape, wounding, maiming, or killing of such inhabitants, are prohibited under the penalty of death, or such other severe punishment as may seem adequate for the gravity of the offense.

A soldier, officer or private, in the act of committing such violence, and disobeying a superior ordering him to abstain from it, may be lawfully killed on the spot by such superior.

Art. 45. All captures and booty belong, according to the modern law of war, primarily to the government of the captor.

Prize money, whether on sea or land, can now only be claimed under local law.

Art. 46. Neither officers nor soldiers are allowed to make use of their position or power in the hostile country for private gain, not even for commercial transactions otherwise legitimate. Offenses to the contrary committed by commissioned officers will be punished with cashiering or such other punishment as the nature of the offense may require; if by soldiers, they shall be punished according to the nature of the offense.

Art. 47. Crimes punishable by all penal codes, such as arson, murder, maiming, assaults, highway robbery, theft, burglary, fraud, forgery, and rape, if committed by an American soldier in a hostile country against its inhabitants, are not only punishable as at home, but in all cases in which death is not inflicted, the severer punishment shall be preferred.

SECTION III

Deserters - Prisoners of war - Hostages - Booty on the battle-field.

* * * *

Art. 49. A prisoner of war is a public enemy armed or attached to the hostile army for active aid, who has fallen into the hands of the captor, either fighting or wounded, on the field or in the hospital, by individual surrender or by capitulation.

All soldiers, of whatever species of arms; all men who belong to the rising en masse of the hostile country; all those who are attached to the army for its efficiency and promote directly the object of the war, except such as are hereinafter provided for; all disabled men or officers on the field or elsewhere, if captured; all enemies who have thrown away their arms and ask

for quarter, are prisoners of war, and as such exposed to the inconveniences as well as entitled to the privileges of a prisoner of war.

Art. 50. Moreover, citizens who accompany an army for whatever purpose, such as sutlers, editors, or reporters of journals, or contractors, if captured, may be made prisoners of war, and be detained as such.

The monarch and members of the hostile reigning family, male or female, the chief, and chief officers of the hostile government, its diplomatic agents, and all persons who are of particular and singular use and benefit to the hostile army or its government, are, if captured on belligerent ground, and if unprovided with a safe conduct granted by the captor's government,

prisoners of war.

Art. 51. If the people of that portion of an invaded country which is not yet occupied by the enemy, or of the whole country, at the approach of a hostile army, rise, under a duly authorized levy en masse to resist the invader, they are now treated as public enemies, and, if captured, are

prisoners of war.

Art. 52. No belligerent has the right to declare that he will treat every captured man in arms of a levy en masse as a brigand or bandit. If, however, the people of a country, or any portion of the same, already occupied by an army, rise against it, they are violators of the laws of

war, and are not entitled to their protection.

Art. 53. The enemy's chaplains, officers of the medical staff, apothecaries, hospital nurses and servants, if they fall into the hands of the American Army, are not prisoners of war, unless the commander has reasons to retain them. In this latter case; or if, at their own desire, they are allowed to remain with their captured companions, they are treated as prisoners of war, and may be exchanged if the commander sees fit.

* * * *

Art. 56. A prisoner of war is subject to no punishment for being a public enemy, nor is any revenge wreaked upon him by the intentional infliction of any suffering, or disgrace, by cruel imprisonment, want of food, by mutilation, death, or any other barbarity.

Art. 57. So soon as a man is armed by a sovereign government and takes the soldier's oath of fidelity, he is a belligerent; his killing, wounding, or other warlike acts are not individual crimes or offenses. No belligerent has a right to declare that enemies of a certain class, color, or

condition, when properly organized as soldiers, will not be treated by him as public enemies.

Art. 58. The law of nations knows of no distinction of color, and if an enemy of the United States should enslave and sell any captured persons of their army, it would be a case for the severest retaliation, if not redressed upon complaint.

The United States cannot retaliate by enslavement; therefore death must be the retaliation for this crime against the law of nations.

Art. 59. A prisoner of war remains answerable for his crimes committed against the captor's army or people, committed before he was captured, and for which he has not been punished by his own authorities.

All prisoners of war are liable to the infliction of retaliatory measures.

* * * *

Art. 70. The use of poison in any manner, be it to poison wells, or food, or arms, is wholly excluded from modern warfare. He that uses it puts himself out of the pale of the law and usages of war.

Art.71. Whoever intentionally inflicts additional wounds on an enemy already wholly disabled, or kills such an enemy, or who orders or encourages soldiers to do so, shall suffer death, if duly convicted, whether he belongs to the Army of the United States, or is an enemy captured after having committed his misdeed.

Art. 72. Money and other valuables on the person of a prisoner, such as watches or jewelry, as well as extra clothing, are regarded by the American Army as the private property of the prisoner, and the appropriation of such valuables or money is considered dishonorable, and is prohibited. Nevertheless, if large sums are found upon the persons of prisoners, or in

their possession, they shall be taken from them, and the surplus, after providing for their own support, appropriated for the use of the army, under the direction of the commander, unless otherwise ordered by the government. Nor can prisoners claim, as private property, large sums found and captured in their train, although they have been placed in the private

luggage of the prisoners.

Art. 73. All officers, when captured, must surrender their side arms to the captor. They may be restored to the prisoner in marked cases, by the commander, to signalize admiration of his distinguished bravery or approbation of his humane treatment of prisoners before his capture. The captured officer to whom they may be restored can not wear them during

captivity.

Art. 74. A prisoner of war, being a public enemy, is the prisoner of the government, and not of the captor. No ransom can be paid by a prisoner of war to his individual captor or to any officer in command. The government alone releases captives, according to rules prescribed by itself.

Art. 75. Prisoners of war are subject to confinement or imprisonment such as may be deemed necessary on account of safety, but they are to be subjected to no other intentional suffering or indignity. The confinement and mode of treating a prisoner may be varied during his captivity

according to the demands of safety.

Art. 76. Prisoners of war shall be fed upon plain and wholesome food, whenever practicable, and treated with humanity.

They may be required to work for the benefit of the captor's government, according to their rank and condition.

Art. 77. A prisoner of war who escapes may be shot or otherwise killed in his flight; but neither death nor any other punishment shall be inflicted upon him simply for his attempt to escape, which the law of war does not consider a crime. Stricter means of security shall be used after an

unsuccessful attempt at escape.

If, however, a conspiracy is discovered, the purpose of which is a united or general escape, the conspirators may be rigorously punished, even with death; and capital punishment may also be inflicted upon prisoners of war discovered to have plotted rebellion against the authorities of the

captors, whether in union with fellow prisoners or other persons.

Art. 78. If prisoners of war, having given no pledge nor made any promise on their honor, forcibly or otherwise escape, and are captured again in battle after having rejoined their own army, they shall not be punished for their escape, but shall be treated as simple prisoners of war, although they will be subjected to stricter confinement.

Art. 79. Every captured wounded enemy shall be medically treated, according to the ability of the medical staff.

Art. 80. Honorable men, when captured, will abstain from giving to the enemy information concerning their own army, and the modern law of war permits no longer the use of any violence against prisoners in order to extort the desired information or to punish them for having given false information.
