Keep in mind the Geneva convention doesn't apply.
But here are the highlights.
http://www.unhchr.ch/html/menu3/b/91.htmArticle 3
In the case of armed conflict not of an international character occurring in the territory of one of the High Contracting Parties, each party to the conflict shall be bound to apply, as a minimum, the following provisions:
1. Persons taking no active part in the hostilities, including members of armed forces who have laid down their arms and those placed hors de combat by sickness, wounds, detention, or any other cause, shall in all circumstances be treated humanely, without any adverse distinction founded on race, colour, religion or faith, sex, birth or wealth, or any other similar criteria.
To this end the following acts are and shall remain prohibited at any time and in any place whatsoever with respect to the above-mentioned persons:
(a) Violence to life and person, in particular murder of all kinds, mutilation, cruel treatment and torture;
(b) Taking of hostages;
(c) Outrages upon personal dignity, in particular, humiliating and degrading treatment;
(d) The passing of sentences and the carrying out of executions without previous judgment pronounced by a regularly constituted court affording all the judicial guarantees which are recognized as indispensable by civilized peoples.
2. The wounded and sick shall be collected and cared for.
An impartial humanitarian body, such as the International Committee of the Red Cross, may offer its services to the Parties to the conflict.
The Parties to the conflict should further endeavour to bring into force, by means of special agreements, all or part of the other provisions of the present Convention.
The application of the preceding provisions shall not affect the legal status of the Parties to the conflict.
Article 13
Prisoners of war must at all times be humanely treated. Any unlawful act or omission by the Detaining Power causing death or
seriously endangering the health of a prisoner of war in its custody is prohibited, and will be regarded as a serious breach of the present Convention. In particular, no prisoner of war may be subjected to physical mutilation or to medical or scientific experiments of any kind which are not justified by the medical, dental or hospital treatment of the prisoner concerned and carried out in his interest.
Likewise, prisoners of war must at all times be protected, particularly against acts of violence or intimidation and against insults and public curiosity.
Measures of reprisal against prisoners of war are prohibited.
BEGINNING OF CAPTIVITY
Article 17
Every prisoner of war, when questioned on the subject, is bound to give only his surname, first names and rank, date of birth, and army, regimental, personal or serial number, or failing this, equivalent information. If he wilfully infringes this rule, he may render himself liable to a restriction of the privileges accorded to his rank or status.
Each Party to a conflict is required to furnish the persons under its jurisdiction who are liable to become prisoners of war, with an identity card showing the owner's surname, first names, rank, army, regimental, personal or serial number or equivalent information, and date of birth. The identity card may, furthermore, bear the signature or the fingerprints, or both, of the owner, and may bear, as well, any other information the Party to the conflict may wish to add concerning persons belonging to its armed forces. As far as possible the card shall measure 6.5 x 10 cm. and shall be issued in duplicate. The identity card shall be shown by the prisoner of war upon demand, but may in no case be taken away from him.
No physical or mental torture, nor any other form of coercion, may be inflicted on prisoners of war to secure from them information of any kind whatever. Prisoners of war who refuse to answer may not be threatened, insulted, or exposed to any unpleasant or disadvantageous treatment of any kind.Prisoners of war who, owing to their physical or mental condition, are unable to state their identity, shall be handed over to the medical service. The identity of such prisoners shall be established by all possible means, subject to the provisions of the preceding paragraph.
The questioning of prisoners of war shall be carried out in a language which they understand.
Chapter III
PENAL AND DISCIPLINARY SANCTIONS
I. General provisions
Article 82
A prisoner of war shall be subject to the laws, regulations and orders in force in the armed forces of the Detaining Power; the Detaining Power shall be justified in taking judicial or disciplinary measures in respect of any offence committed by a prisoner of war against such laws, regulations or orders. However, no proceedings or punishments contrary to the provisions of this Chapter shall be allowed.
If any law, regulation or order of the Detaining Power shall declare acts committed by a prisoner of war to be punishable, whereas the same acts would not be punishable if committed by a member of the forces of the Detaining Power, such acts shall entail disciplinary punishments only.
Article 83
In deciding whether proceedings in respect of an offence alleged to have been committed by a prisoner of war shall be judicial or disciplinary, the Detaining Power shall ensure that the competent authorities exercise the greatest leniency and adopt, wherever possible, disciplinary rather than judicial measures.
Article 84
A prisoner of war shall be tried only by a military court, unless the existing laws of the Detaining Power expressly permit the civil courts to try a member of the armed forces of the Detaining Power in respect of the particular offence alleged to have been committed by the prisoner of war.In no circumstances whatever shall a prisoner of war be tried by a court of any kind which does not offer the essential guarantees of independence and impartiality as generally recognized, and, in particular, the procedure of which does not afford the accused the rights and means of defence provided for in Article 105.
Article 85
Prisoners of war prosecuted under the laws of the Detaining Power for acts committed prior to capture shall retain, even if convicted, the benefits of the present Convention.
Article 86
No prisoner of war may be punished more than once for the same act, or on the same charge.
Article 87
Prisoners of war may not be sentenced by the military authorities and courts of the Detaining Power to any penalties except those provided for in respect of members of the armed forces of the said Power who have committed the same acts.
When fixing the penalty, the courts or authorities of the Detaining Power shall take into consideration, to the widest extent possible, the fact that the accused, not being a national of the Detaining Power, is not bound to it by any duty of allegiance, and that he is in its power as the result of circumstances independent of his own will. The said courts or authorities shall be at liberty to reduce the penalty provided for the violation of which the prisoner of war is accused, and shall therefore not be bound to apply the minimum penalty prescribed.
Collective punishment for individual acts, corporal punishments, imprisonment in premises without daylight and, in general, any form of torture or cruelty, are forbidden.
No prisoner of war may be deprived of his rank by the Detaining Power, or prevented from wearing his badges.
Article 88
Officers, non-commissioned officers and men who are prisoners of war undergoing a disciplinary or judicial punishment, shall not be subjected to more severe treatment than that applied in respect of the same punishment to members of the armed forces of the Detaining Power of equivalent rank.
A woman prisoner of war shall not be awarded or sentenced to a punishment more severe, or treated whilst undergoing punishment more severely, than a woman member of the armed forces of the Detaining Power dealt with for a similar offence.
In no case may a woman prisoner of war be awarded or sentenced to a punishment more severe, or treated whilst undergoing punishment more severely, than a male member of the armed forces of the Detaining Power dealt with for a similar offence.
Prisoners of war who have served disciplinary or judicial sentences may not be treated differently from other prisoners of war.
II. Disciplinary sanctions
Article 89
The disciplinary punishments applicable to prisoners of war are the following:
1. A fine which shall not exceed 50 per cent of the advances of pay and working pay which the prisoner of war would otherwise receive under the provisions of Articles 60 and 62 during a period of not more than thirty days.
2. Discontinuance of privileges granted over and above the treatment provided for by the present Convention.
3. Fatigue duties not exceeding two hours daily.
4. Confinement.
The punishment referred to under (3) shall not be applied to officers.
In no case shall disciplinary punishments be inhuman, brutal or dangerous to the health of prisoners of war.
Article 90
The duration of any single punishment shall in no case exceed thirty days. Any period of confinement awaiting the hearing of a disciplinary offence or the award of disciplinary punishment shall be deducted from an award pronounced against a prisoner of war.
The maximum of thirty days provided above may not be exceeded, even if the prisoner of war is answerable for several acts at the same time when he is awarded punishment, whether such acts are related or not.
The period between the pronouncing of an award of disciplinary punishment and its execution shall not exceed one month.
When a prisoner of war is awarded a further disciplinary punishment, a period of at least three days shall elapse between the execution of any two of the punishments, if the duration of one of these is ten days or more.
Article 91
The escape of a prisoner of war shall be deemed to have succeeded when:
1. He has joined the armed forces of the Power on which he depends, or those of an allied Power;
2. He has left the territory under the control of the Detaining Power, or of an ally of the said Power;
3. He has joined a ship flying the flag of the Power on which he depends, or of an allied Power, in the territorial waters of the Detaining Power, the said ship not being under the control of the last-named Power.
Prisoners of war who have made good their escape in the sense of this Article and who are recaptured, shall not be liable to any punishment in respect of their previous escape.
Article 92
A prisoner of war who attempts to escape and is recaptured before having made good his escape in the sense of Article 91 shall be liable only to a disciplinary punishment in respect of this act, even if it is a repeated offence.
A prisoner of war who is recaptured shall be handed over without delay to the competent military authority.
Article 88, fourth paragraph, notwithstanding, prisoners of war punished as a result of an unsuccessful escape may be subjected to special surveillance. Such surveillance must not affect the state of their health, must be undergone in a prisoner of war camp, and must not entail the suppression of any of the safeguards granted them by the present Convention.
Article 93
Escape or attempt to escape, even if it is a repeated offence, shall not be deemed an aggravating circumstance if the prisoner of war is subjected to trial by judicial proceedings in respect of an offence committed during his escape or attempt to escape.
In conformity with the principle stated in Article 83, offences committed by prisoners of war with the sole intention of facilitating their escape and which do not entail any violence against life or limb, such as offences against public property, theft without intention of self-enrichment, the drawing up or use of false papers, the wearing of civilian clothing, shall occasion disciplinary punishment only.
Prisoners of war who aid or abet an escape or an attempt to escape shall be liable on this count to disciplinary punishment only.
Article 94
If an escaped prisoner of war is recaptured, the Power on which he depends shall be notified thereof in the manner defined in Article 122, provided notification of his escape has been made.
Article 95
A prisoner of war accused of an offence against discipline shall not be kept in confinement pending the hearing unless a member of the armed forces of the Detaining Power would be so kept if he were accused of a similar offence, or if it is essential in the interests of camp order and discipline.
Any period spent by a prisoner of war in confinement awaiting the disposal of an offence against discipline shall be reduced to an absolute minimum and shall not exceed fourteen days.
The provisions of Articles 97 and 98 of this Chapter shall apply to prisoners of war who are in confinement awaiting the disposal of offences against discipline.
Article 96
Acts which constitute offences against discipline shall be investigated immediately.
Without prejudice to the competence of courts and superior military authorities, disciplinary punishment may be ordered only by an officer having disciplinary powers in his capacity as camp commander, or by a responsible officer who replaces him or to whom he has delegated his disciplinary powers.
In no case may such powers be delegated to a prisoner of war or be exercised by a prisoner of war.
Before any disciplinary award is pronounced, the accused shall be given precise information regarding the offences of which he is accused, and given an opportunity of explaining his conduct and of defending himself. He shall be permitted, in particular, to call witnesses and to have recourse, if necessary, to the services of a qualified interpreter. The decision shall be announced to the accused prisoner of war and to the prisoners' representative.
A record of disciplinary punishments shall be maintained by the camp commander and shall be open to inspection by representatives of the Protecting Power.
Article 97
Prisoners of war shall not in any case be transferred to penitentiary establishments (prisons, penitentiaries, convict prisons, etc.) to undergo disciplinary punishment therein.
All premises in which disciplinary punishments are undergone shall conform to the sanitary requirements set forth in Article 25. A prisoner of war undergoing punishment shall be enabled to keep himself in a state of cleanliness, in conformity with Article 29.
Officers and persons of equivalent status shall not be lodged in the same quarters as non-commissioned officers or men.
Women prisoners of war undergoing disciplinary punishment shall be confined in separate quarters from male prisoners of war and shall be under the immediate supervision of women.
Article 98
A prisoner of war undergoing confinement as a disciplinary punishment, shall continue to enjoy the benefits of the provisions of this Convention except in so far as these are necessarily rendered inapplicable by the mere fact that he is confined. In no case may he be deprived of the benefits of the provisions of Articles 78 and 126.A prisoner of war awarded disciplinary punishment may not be deprived of the prerogatives attached to his rank.
Prisoners of war awarded disciplinary punishment shall be allowed to exercise and to stay in the open air at least two hours daily.
They shall be allowed, on their request, to be present at the daily medical inspections. They shall receive the attention which their state of health requires and, if necessary, shall be removed to the camp infirmary or to a hospital.
They shall have permission to read and write, likewise to send and receive letters. Parcels and remittances of money, however, may be withheld from them until the completion of the punishment; they shall meanwhile be entrusted to the prisoners' representative, who will hand over to the infirmary the perishable goods contained in such parcels.
