Mr. Justice Douglas
delivered the opinion of the Court.
Article of War 92, 10 U. S. C. (1946 ed., Supp. IV) § 1564, which, prior to the adoption of the Uniform Code of Military Justice, governed trials for murder or rape before courts-martial, contained a proviso “That no person shall be tried by court-martial for murder or rape committed within the geographical limits of the States of the Union and the District of Columbia in time of peace.”
The question for decision concerns the meaning of the words “in time of peace” in the context of Article 92.
Petitioner, while serving with the United States Army in France, was convicted by a court-martial, dishonorably discharged, and sentenced to prison for 20 years. He was serving that sentence in the custody of the Army at Camp Cooke, California, when he was convicted by a court-martial of the crime of conspiracy to commit murder. This offense occurred on June 10, 1949, at Camp Cooke. The question is whether June 10, 1949, was “in time of peace” as the term was used in the 92d Article. The question was raised by a petition for a writ of habeas corpus challenging the jurisdiction of the court-martial. Both the District Court (148 F. Supp. 23) and the Court of Appeals (248 F. 2d 783) ruled against petitioner. We granted certiorari, 356 U. S. 911.
The Germans surrendered on May 8, 1945 (59 Stat. 1857), the Japanese on September 2,1945 (59 Stat. 1733). The President on December 31, 1946, proclaimed the cessation of hostilities, adding that “a state of war still exists.” 61 Stat. 1048. In 1947, Senate Joint Resolution 123 was passed (61 Stat. 449) which terminated, inter alia, several provisions of the Articles of War but did not mention Article 92. The war with Germany terminated October 19, 1951, by a Joint Resolution of Congress (65 Stat. 451) and a Presidential Proclamation (66 Stat. c3). And on April 28, 1952, the formal declaration of peace and termination of war with Japan was proclaimed by the President (66 Stat. c31), that being the effective date of the Japanese Peace Treaty. Since June 10, 1949 — the critical date involved here — preceded these latter dates, and since no previous action by the political branches of our Government had specifically lifted Article 92 from the “state of war” category, it is argued that we were not then “in time of peace” for the purposes of Article 92. That argument gains support from a dictum in Kahn v. Anderson, 255 U. S. 1, 9-10, that the term “in time of peace” as used in Article 92 “signifies peace in the complete sense, officially declared.” Of like tenor are generalized statements that the termination of a “state of war” is “a political act” of the other branches of Government, not the Judiciary. See Ludecke v. Watkins, 335 U. S. 160, 169. We do not think that either of those authorities is dispositive of the present controversy. A more particularized and discriminating analysis must be made. We deal with a term that must be construed in light of the precise facts of each case and the impact of the particular statute involved. Congress in drafting laws may decide that the Nation may be “at war” for one purpose, and “at peace” for another. It may use the same words broadly in one context, narrowly in another. The problem of judicial interpretation is to determine whether “in the sense of this law” peace had arrived. United States v. Anderson, 9 Wall. 56, 69. Only mischief can result if those terms are given one meaning regardless of the statutory context.
In the Kahn case, the offense was committed on July 29, 1918, and the trial started November 4, 1918 — both dates being before the Armistice. It is, therefore, clear that the offense was not committed “in time of peace.” Moreover, a military tribunal whose jurisdiction over a case attaches in a time of actual war does not lose jurisdiction because hostilities cease. Once a military court acquires jurisdiction that jurisdiction continues until the end of the trial and the imposition of the sentence. See Carter v. McClaughry, 183 U. S. 365, 383. The broad comments of the Court in the Kahn case on the meaning of the term “in time of peace” as used in Article 92 were, therefore, quite unnecessary for the decision.
Ludecke v. Watkins, 335 U. S. 160, belongs in a special category of cases dealing with the power of the Executive or the Congress to deal with the aftermath of problems which a state of war brings and which a cessation of hostilities does not necessarily dispel. That case concerns the power of the President to remove an alien enemy after hostilities have ended but before the political branches have declared the state of war ended. Hamilton v. Kentucky Distilleries & Warehouse Co., 251 U. S. 146, involves the constitutionality under the war power of a prohibition law passed in 1918 after the armistice with Germany was signed and to be operative “until the conclusion of the present war and thereafter until the termination of demobilization, the date of which shall be determined and proclaimed by the President of the United States.” Woods v. Miller Co., 333 U. S. 138, concerns the constitutionality of control of housing rentals promulgated after hostilities were ended and before peace was formally declared. These cases deal with the reach of the war power, as a source of regulatory authority over national affairs, in the aftermath of hostilities. The earlier case of McElrath v. United States, 102 U. S. 426, is likewise irrelevant to our problem. It was a suit for back pay by an officer, the outcome of which turned on a statute which allowed dismissal of an officer from the service “in time of peace” only by court-martial. The President had made the dismissal; and the Court held that such action, being before August 20, 1866, when the Presidential Proclamation announced the end of the rebellion and the existence of peace, was lawful, since there was extrinsic evidence that Congress did not intend the statute to be effective until the date of the Proclamation.
Our problem is not controlled by those cases. We deal with the term “in time of peace” in the setting of a grant of power to military tribunals to try people for capital offenses. Did Congress design a broad or a narrow grant of authority? Is the authority of a court-martial to try a soldier for a civil crime, such as murder or rape, to be generously or strictly construed? Cf. Duncan v. Kahanamoku, 327 U. S. 304.
We do not write on a clean slate. The attitude cf a free society toward the jurisdiction of military tribunals — our reluctance to give them authority to try people for nonmilitary offenses — has a long history.
We reviewed both British and American history, touching on this point, in Reid v. Covert, 354 U. S. 1, 23-30. We pointed out the great alarms sounded when James II authorized the trial of soldiers for nonmilitary crimes and the American protests that mounted when British courts-martial impinged on the domain of civil courts in this country. The views of Blackstone on military jurisdiction became deeply imbedded in our thinking: “The necessity of order and discipline in an army is the only thing which can give it countenance; and therefore it ought not to be permitted in time of peace, when the king’s courts are open for all persons to receive justice according to the laws of the land.” 1 Blackstone’s Commentaries 413. And see Hale, History and Analysis of the Common Law of England (1st ed. 1713), 40-41. We spoke in that tradition in Toth v. Quarles, 350 U. S. 11, 22, “Free countries of the world have tried to restrict military tribunals to the narrowest jurisdiction deemed absolutely essential to maintaining discipline among troops in active service.”
The power to try soldiers for the capital crimes of murder and rape was long withheld. Not until 1863 was authority granted. 12 Stat. 736. And then it was restricted to times of “war, insurrection, or rebellion.” The theory was that the civil courts, being open, were wholly qualified to handle these cases. As Col. William Winthrop wrote in Military Law and Precedents (2d ed. 1920) 667, about this 1863 law:
“Its main object evidently was to provide for the punishment of these crimes in localities where, in consequence of military occupation, or the prevalence of martial law, the action of the civil courts is suspended, or their authority can not be exercised with the promptitude and efficiency required by the exigencies of the period and the necessities of military government.”
Civil courts were, indeed, thought to be better qualified than military tribunals to try nonmilitary offenses. They have a more deeply engrained judicial attitude, a more thorough indoctrination in the procedural safeguards necessary for a fair trial. Moreover, important constitutional guarantees come into play once the citizen— whether soldier or civilian — is charged with a capital crime such as murder or rape. The most significant of these is the right to trial by jury, one of the most important safeguards against tyranny which our law has designed. We must assume that the Congress, as well as the courts, was alive to the importance of those constitutional guarantees when it gave Article 92 its particular phrasing. Statutory language is construed to conform as near as may be to traditional guarantees that protect the rights of the citizen. See Ex parte Endo, 323 U. S. 283, 301-304; Rowoldt v. Perfetto, 355 U. S. 115; Kent v. Dulles, 357 U. S. 116, 129. We will attribute to Congress a purpose to guard jealously against the dilution of the liberties of the citizen that would result if the jurisdiction of military tribunals were enlarged at the expense of civil courts. General Enoch H. Crowder, Judge Advocate General, in testifying in favor of the forerunner of the present proviso of Article 92, spoke of the protection it extended the officer and soldier by securing them “a trial by their peers.” We think the proviso should be read generously to achieve that end.
We refused in Duncan v. Kahanamoku, 327 U. S. 304, to construe “martial law,” as used in an Act of Congress, broadly so as to supplant all civilian laws and to substitute military for judicial trials of civilians not charged with violations of the law of war. We imputed to Congress an attitude that was more consonant with our traditions of civil liberties. We approach the analysis of the term “in time of peace” as used in Article 92 in the same manner. Whatever may have been the plan of a later Congress in continuing some controls long after hostilities ceased, we cannot readily assume that the earlier Congress used “in time of peace” in Article 92 to deny soldiers or civilians the- benefit of jury trials for capital offenses four years after all hostilities had ceased. To hold otherwise would be to make substantial rights turn on a fiction. We will not presume that Congress used the words “in time of peace” in that sense. The meaning attributed to them is at war with common sense, destructive of civil rights, and unnecessary for realization of the balanced scheme promulgated by the Articles of War. We hold that June 10,1949, was “in time of peace” as those words were used in Article 92. This conclusion makes it unnecessary for us to consider the other questions presented, including the constitutional issues which have been much mooted.
Reversed.
Mr. Justice Frankfurter took no part in the consideration or decision of this case.
64 Stat. 108, 10 U. S. C. (Supp. V) § 801 et seq., enacted May 5, 1950. For the present provisions governing murder and rape see Articles 118, 120.
Article 92 read as follows:
“Any person subject to military law found guilty of murder shall suffer death or imprisonment for life, as a court-martial may direct; but if found guilty of murder not premeditated, he shall be punished as a court-martial may direct. Any person subject to military law who is found guilty of rape shall suffer death or such other punishment as a court-martial may direct: Provided, That no person shall be tried by court-martial for murder or rape committed within the geographical limits of the States of the Union and the District of Columbia in time of peace.”
See H. R. Rep. No. 2682, 79th Cong., 2d Sess.; H. R. Rep. No. 799, 80th Cong., 1st Sess.; S. Rep. No. 339, 80th Cong., 1st Sess.
In Givens v. Zerbst, 255 U. S. 11, a companion ease to the Kahn case, the crime was committed on September 28, 1918, and the court-martial convened on October 30, 1918.
Prior to that time only state courts could try a soldier for murder or rape. Coleman v. Tennessee, 97 U. S. 509, 514. And that Act was construed as not giving the military exclusive jurisdiction.
“With the known hostility of the American people to any interference by the military with the regular administration of justice in the civil courts, no such intention should be ascribed to Congress in the absence of clear and direct language to that effect.” Id.
We said in Toth v. Quarles, supra, pp. 17-19:
. . there is a great difference between trial by jury and trial by selected members of the military forces. It is true that military personnel because of their training and experience may be especially competent to try soldiers for infractions of military rules. Such training is no doubt particularly important where an offense charged against a soldier is purely military, such as disobedience of an order, leaving post, etc. But whether right or wrong, the premise underlying the constitutional method for determining guilt or innocence in federal courts is that laymen are better than specialists to perform this task. This idea is inherent in the institution of trial by jury.
“Juries fairly chosen from different walks of life bring into the jury box a variety of different experiences, feelings, intuitions and habits. Such juries may reach completely different conclusions than would be reached by specialists in any single field, including specialists in the military field. On many occasions, fully known to the Founders of this country, jurors — plain people — have manfully stood up in defense of liberty against the importunities of judges and despite prevailing hysteria and prejudices. The acquittal of William Penn is an illustrious example. Unfortunately, instances could also be cited where jurors have themselves betrayed the cause of justice by verdicts based on prejudice or pressures. In such circumstances independent trial judges and independent appellate judges have a most important place under our constitutional plan since they have power to set aside convictions.”
See S. Rep. No. 130, 64th Cong., 1st Sess., p. 88'.
General Crowder was opposed to a proposal of the General Staff that capital crimes even when committed in this country be tried by court-martial as well as by civil courts. He said, “We never have had that law, and I doubt very much whether it is desirable to divorce the Army to that extent from accountability in the civil courts. . . . I think that here in the United States proper the Army should be under the same accountability as civilians for capital crimes.” Id., at 32.
The method employed by the Executive and the Congress in terminating wartime controls was different at the end of World War II than it was when World War I terminated. In the earlier war most of the legislation dependent on the existence of a state of war was terminated at one time. See 41 Stat. 1359, H. R. Rep. No. 1111, 66th Cong., 3d Sess.; S. Rep. No. 706, 66th Cong., 3d Sess. At the end of World War II Congress acted more selectively. See H. R. Rep. No. 2682, 79th Cong., 2d Sess. Thus Congress by S. J. Res. 123, 80th Cong., 1st Sess., declared that, for the purpose of construing specified statutes (among them certain Articles of War — but not Article 92), the effective date of the Resolution should be deemed the termination date of the state of war. The fact that Article 92 was not in that list leaves the problem where it was at the time the law was enacted. The failure to repeal, alter, or amend this law plainly has no bearing on its original purpose.
