On Rehearing En Banc
SPOTTSWOOD W. ROBINSON, III, Circuit Judge:Appellant was convicted by a jury on both counts of an indictment respectively charging assault with a dangerous weapon and robbery.1 His sentence was a commitment pursuant to provisions of the Federal Youth Corrections Act.2 His sole contention on this appeal is that the conviction was vitiated by a series of trial events, including prominently a version of the Allen charge,3 which in his view improperly induced the verdict the jury returned.
Upon careful consideration of the record, we conclude that the conviction should be reversed, and that future rendition of Allen-type charges must conform to the standard which has been approved by the American Bar Association and adopted by the Third and Seventh Circuits.4 Our reasons for these conclusions follow a summary of the relevant facts.
I
James C. Drayton, Jr., was the victim of an armed assault and an accompanying robbery - at his apartment in the early hours of a February morning. Shortly after midnight, awakened by the sound of broken glass and footsteps, he went into his kitchen in time to see two men hastily exiting through the back door.5 A police investigation of the incident apparently was unfruitful, and Drayton returned to bed about 5:00 a. m. He was again aroused about 6:30 a. m. by a knock on his front door, and in response to his inquiry as to who was there, a male voice answered “Annette’s brother.” Drayton opened the door because, in his words, “I figured after he said Annette’s brother, I knew Annette.” 6
Two men entered the apartment, then still unlighted, and one, later identified as appellant, promptly knocked Drayton down with a blow to the head. As Drayton lay face down to the floor with the same man standing over him with a pistol, and later with Drayton’s own shotgun,7 the other man8 gathered money and articles of value in the apartment. While the ransacking was in progress, Drayton attempted to arise, and was again struck in the head, this time with the shotgun. A struggle for the shotgun ensued, and Drayton commenced shouting, whereupon the two men left the apartment with part of their collected loot.
The police were again summoned to Drayton’s apartment. Drayton was taken to a hospital, where cuts about his head were stitched, and on his return he gave the police the relevant details. Accompanied by Drayton, the police went to the apartment of Annette Thomas, whom he knew, but no one was there. Somewhat later the same day, after some sleuthing on his own, Drayton learned that Miss Thomas had a brother, our appellant, whose address Drayton also procured. There appellant was ar*1180rested, and was identified by Drayton as one of his assailants.9
Such was the case portrayed by the Government’s evidence at trial and, save for appellant’s identity as a participant in the offenses, it was uncontested. Appellant denied his complicity in the affair, asserting that he was at home in bed when the offenses were committed, and in this claim he was partially corroborated by the testimony, of his mother and a cousin. A motion for a judgment of acquittal, made initially on completion of the Government’s case in chief and renewed when all the evidence was in, was denied.
The trial judge included among his instructions to the jury, before its retirement for deliberations, some of the ingredients of the Allen charge. In that aspect the judge counseled the jury as follows:
In a large portion of the cases absolute certainty cannot be expected, although the verdict must be the verdict of each individual juror and not a mere acquiescence in the conclusion of your fellow jurors, yet you should examine the question submitted with candor and proper regard and deference for the opinion of each other. It is your duty to decide the case if you can conscientiously do so. You should listen to each other’s arguments with a disposition to be convinced. If much the larger number of jurors are for conviction, a dissenting juror should consider whether his doubt is a reasonable one which makes no impression upon the minds of so many jurors equally honest, equally intelligent with himself.
If on the other hand the majority are for acquittal, the minority ought to ask themselves whether they might not reasonably doubt the correctness of a judgment which is not concurred in by the majority.
After the jury had deliberated about an hour, it sent to the judge a note advising that “[w]e, the jury, cannot come to an agreement.” Thereupon, in the jury’s absence, the judge, expressing the view that “ [t]his is not a case we should have to retry,” informed counsel of his intention to excuse the jurors for the day 10 but to reconvene them on the following day for further deliberations; and this course the judge pursued, over vigorous objection by defense counsel. The jury was returned to the courtroom,11 whereupon the judge announced that he was “not going to declare a mistrial, and thereby require a retrial of this case before some other jury.” 12 Rather, he explained, he was excusing the jurors at that time to “come back tomorrow morning at 9:30 with a fresh mind and a night’s sleep and seek to reach a verdict about the matter one way or the other.”13 He added that he was “sure you ladies and *1181gentlemen know we have a substantial backlog of work, and to spend another day before another jury retrying this case just doesn’t make sense to me.” 14 He again admonished the jurors to “[s]ee if you can’t decide and come to a verdict, think about it overnight individually.”15
The jury reconvened at the appointed time. After about two hours of deliberations, interfused with an in-courtroom rereading of Drayton’s testimony at its request, it returned a verdict finding appellant guilty on both counts of the indictment. This appeal followed.
II
Every defendant in a federal criminal case has the right to have his guilt found, if found at all, only by the unanimous verdict of a jury of his peers.16 Any undue intrusion by the trial judge into this exclusive province of the jury is error of the first magnitude. When efforts to secure a verdict from the jury reach the point that a single juror may be coerced into surrendering views conscientiously entertained, the jury’s province is invaded and the requirement of unanimity is diluted.17 It is against these considerations that
we must evaluate any judicial effort to avoid or break a deadlocked jury.
The trial judge is, of course, under a duty to lend guidance to the jury through instructions as to the governing principles of law, including those which define for the jurors their obligations as jurors. It was quite, obviously, in an attempt to enlighten the jury in the latter regard that the judge embraced some of the Allen admonitions within his charge. But the line separating proper guidance from improper coercion is fine, and its precise location, is not always clear. In the case before us, however, the judge urged a verdict, not only through Allen admonitions, but by other expressions to the jury as well. The issue appellant presents is whether in toto the urging — the individual elements of which we examine separately — was so great as possibly to exert a coercive influence upon the jury.
Just four years ago, in Fulwood v. United States,18 this court upheld an application of the Allen charge against claims that it was coercive, not only per se but also in the form and under the special circumstances given.19 However, the court indicated the desirability of avoiding variant formulations and urged *1182that the trial judges “consistently use a form of instruction plainly within Allen”.20 Besides, we have also acknowledged that the charge, even when unem-bellished by further exhortations, is “potentially coercive;”21 that “its content and manner of use deserve scrutiny.” 22 We are mindful, too, of “the widening challenge”23 to the charge, even in its pristine text, by an increasing — and increasingly concerned — corps of critics.24
Moreover, we have had occasion to warn that the Allen charge “approaches the limits to which the court should go in suggesting to jurors the desirability of agreement and avoidance of the necessity of a retrial before another jury.” 25 We are aware of holdings that in particular formulations or under particular circumstances the charge may indeed be coercive;26 in Williams v. United States,27 we ourselves reversed a conviction following an Allen charge importing new ingredients and given after the judge’s inquiry as to whether there was “a clear minority” of jurors.28 Where, as here, comments to the jury are both Allen-plus29 and Fulwood-plus,30 the situation demands close examination to determine whether under all circumstances it is likely to have been coercive.
Ill
Improper duress upon a deadlocked jury does not seek its only source in threats of physical abuse.31 Communications from judge to jury are unduly constraining whenever they possess a substantial propensity for prying individual jurors loose from beliefs they honestly have.32 The jury is coerced, the Supreme Court has held, when it is told that “[y]ou have got to reach a decision in this case,” 33 and in much the *1183same category is the admonition in this case that “you ought to be able to agree on a verdict.” 34 Statements of this sort reflect the judge’s assessment that the factual issues bear relatively easy resolution, and pressure jurors, who in their own endeavors have not found it so, to come to some result at all costs.
So also, in somewhat similar fashion, do expressions emphasizing the desirability of achieving a verdict as a means of avoiding the necessity of a retrial.35 Equally pressuring are statements susceptible to an interpretation reflecting unwholesomely upon minority jurors simply because they happen to be in the minority.36 “No juror should be induced to agree to a verdict by a fear that a failure so to agree will be regarded by the public as reflecting upon either his intelligence, or his integrity.” 37
The record before us portrays the sequence of events which in combination generated, in some measure, each of these undesirable elements. When the jury first announced its inability to agree, the judge had already given a “potentially coercive”38 Allen instruction, and his further efforts to solicit a verdict entered the realm of Allen- and Fwiwood-plus. The judge’s initial response to the jury’s announcement of a deadlock was a declaration that he was “not going to declare a mistrial, and thereby require a retrial of this case before some other jury.” 39 He referred, too, to the court’s “substantial backlog of work,” and voiced the feeling that “to spend another day before another jury retrying this case just doesn’t make sense to me.” 40
It seems not unlikely that jurors faithful to their oaths might have been troubled in attempting to reach a verdict on the proof introduced at the trial. The crucial issue was the identity of one of Drayton’s attackers, ostensibly the one who said he was “Annette’s brother” immediately prior to the attack. The Government’s case against appellant rested on Drayton’s identification, but appellant presented a corroborated alibi for the time of the crimes. The jury had to ponder the credibility of the witnesses as well as judge the reliability of the victim’s identification in the face of the suggestive and perhaps improbable self-identification attributed to appellant.41 Equivocal evidence can raise problems for conscientious jurors, and increase their susceptibility to judicial prodding for a verdict they seem otherwise unable to reach.42
Particularly in these days of burgeoning litigation, we share the trial judge’s sensitivity to the need for adjustment of *1184judicial processes to the point of highest efficiency. But while there is need to expedite the work of the courts, this cannot be at the expense of the call of conscience. Indeed, it may well be that a hung jury might lead the prosecutor to reconsider whether the case, particularly a close or weak case, should be presented again to a jury — so that a mistrial need not necessarily “require” a retrial, as the trial judge told the jurors.43 We have no doubt whatever that the judge acted out of the best of motives, and that any coercion of the jury was entirely unintended. The events transpiring, however, invoke our responsibility to appraise the activities complained of, not by the good intentions behind them, but in terms of their probable impact upon the jury. All circumstances considered, we think those activities strayed beyond legitimate bounds, with a substantial probability of prejudice to the accused, and with the result that the judgment of appellant’s conviction cannot stand.
IV
Our conclusion that the conviction must be reversed for actual, though undesigned, coercion of the jury is an appraisal we could make only after a very considerable expenditure of judicial time and energy. And even as we view in retrospect the demands of this case, we realize, from the number of AUencharge complaints reaching this court, that they are not unique, but frequently recur. So it is that the drain on appellate resources made by Allen-charge controversies leads us to focus upon means whereby the seemingly inevitable aberrations of the charge can be reduced or eradicated.
In our recent Johnson opinion,44 we examined and expressed our approval of the American Bar Association’s standard for treatment of the problem of deadlocked juries45 and a form of instruction it deemed harmonious therewith.46 We need not repeat the compre*1185hensive discussion in that opinion; it suffices to remind that we isolated, as “[a] prime consideration motivating the promulgation of the ABA Standard * * * the large amount of litigation which the use of the original Allen charge has engendered.” 47 We pointed out that “[o]ne of the sources of trouble on appeal has been that the language actually used tends to vary from judge to judge, and this lack of uniformity in a delicate context is full of pitfalls.” 48 We took a hard look at “the majority-minority element of the Allen charge” 49— advising that minority jurors owe deference to the majority — which two sentences of the charge before us featured. We noted that abandonment of this element “may well be in the interest of the efficient administration of justice” because that “would avoid recurring controversies, turning upon subtle questions of coercion in the context of each case.” 50
Further use of the Allen charge in usual form has been banned in two federal circuits by exertions of supervisory authority.51 In United States v. Fioravanti,52 the Third Circuit, characterizing use of the charge as “an invitation for perennial appellate review,”53 outlawed prospectively the “majority-minority” instruction partly because of “the profound difficulty in confining its use within just and equitable bounds,” 54 and recommended a model similar to the ABA-endorsed instruction for use by judges disposed to charge jurors on consultation inter sese.55 In United States v. Brown,56 the ^ Seventh Circuit, influenced by the administrative difficulties associated with Allen-type charges,57 decided that “it would serve the interests of justice to require under our supervisory power that, in the future, district courts within this Circuit when faced with deadlocked juries comply with the” ABA standard.58 Two state courts, for substantially similar reasons, have proscribed the Allen charge on supervisory grounds.59
A decade ago, the Supreme Court of Arizona declared “that the evils [of the Allen charge] far outweigh the benefits.”60 Our opinion in Johnson *1186made it clear that we felt exactly the same way.61 There, we advanced the ABA standard and its implementing instruction as recommendations to trial judges.62 Upon further reflection, and in light of the additional circumstances presented by the case at bar, we think it is in furtherance of the interest of justice to take a step which the court was not ready to take in the circumstances of Johnson, and to exercise our supervisory power, with a generally prospective ruling, to require trial judges to comply with the ABA standard.
We have already noted that in Ful-wood, Judge (now Chief Justice) Burger urged the trial bench to “consistently use a form of instruction plainly within Allen.”63 Yet, in the course of time, the expressions actually used by trial judges, in this case and others, have added an extra measure of influence in the instructions given to juries. We believe that appellate courts should no longer be burdened with the necessities and niceties — and the concomitant uncertainties — of gauging various Allen-type renditions in terms of the coerciveness of their impact. We are persuaded, too, by the volume and complexity of litigation generated by the Allen charge, that its continued unrestricted use is incompatible with sound judicial administration. We have before us today what was not available when Fulwood issued —the standard that was painstakingly reviewed and approved by the designated committee of the American Bar Association’s Project on Minimum Standards for Criminal Justice, that was adopted by its House of Delegates, and that was mandated by opinions of the Third and Seventh Circuits. We think the time has come to follow the path they have traveled and lay down the same mandate.
The case at bar, unlike Johnson, presents the occasion we deem appropriate for doing so. With the court now convened en b&nc, supervisory jurisdiction is clear,64 and the situation before us underscores the impositions which Allen charges in usual script can make for. The contention on this appeal was not, as in Johnson, confined to the content of the trial judge’s Allen instructions, but extended beyond to a close and difficult issue of coercion in fact under the surrounding circumstances. That issue we have resolved, but the process has exacted a heavy toll in terms of judicial time and effort, and even so its contribution to the ultimate disposition of this litigation is uncertain. There remains in the case a serious problem as to whether any new in-court identification of appellant by Drayton could survive a one-man showup at which appellant, without counsel and 24 hours after the offenses were committed, was first identified as a participant.65 While we do not undertake decision of that question,66 the is*1187sue will be open in the event of another trial following our remand. Furthermore, the record reveals that appellant was conditionally released from the commitment imposed by his sentence before the briefs on this appeal could be filed.67
While we do not intimate a view as to what more can or should be done in this case, we are permitted the realism of doubting whether further proceedings would actually eventuate, especially if a new trial is required. We conclude that the interest of justice will in the future be better served, not by periodically laboring the refinements of Aiiew-charge language or eoerciveness concepts, but by adherence to the broader and sounder doctrine, which was recommended but left permissive in Johnson for the time being, as a requirement governing instructions given by trial judges to juries subsequent to the date of this opinion.
Accordingly, in the exercise of our supervisory power over the administration of the law in this circuit,68 we adopt the ABA standard69 for the guidelines which future renditions of Alien-type charges must abide, and the ABA approved instruction70 as the vehicle for informing jurors of their responsibilities in situations wherein judges decide to do so.71 This new rule, “[a]s a prophylactic device to eliminate future vexation,”72 will benefit only those whose jury trials are conducted hereafter,73 including, of course, any retrial to which appellant may be subjected.74
We do not regard this holding as a reconsideration or overruling of our decision in Fulwood.75 We have not held that the Allen charge is per se coercive; rather, we have predicated our decision on the needs of judicial administration, a ground which, as Johnson points out, Fulwood did not consider, but which commended itself to the American Bar Association.76 What we say, in sum, is that the time has come “to focus [the Allen] charge on its major function of counseling the jury to consult openmindedly with a disposition to hearken to fellow-jurors, and to agree when no violation of conscience is involved.”77 That objective, we are convinced, can become a reality only through the supervisory exercise in which we engage today.78
*1188At oral argument the Government, anticipating that we might modify our rule, proposed that we not adopt the ABA-approved instruction but instead accept a variant wording.79 Our initial reaction is that the wording proposed is not a major improvement. Perhaps further study would confirm that initial view. But we are not disposed to open the door to variants in language, having in mind that it was through just such a process that the courts were led into the increasing difficulties we outlined earlier in this opinion. We do not consider the ABA’s standard or its model instruction as graven in stone. The Judicial Conference for this circuit has approved the concept of a committee to implement the ABA’s criminal justice standards,80 and it may be that in due course some modification will emerge as appropriate, either by virtue of general reconsideration or the need for adaptation to local conditions. But we think if there is to be any change in wording, it should be one that is carefully considered on a broad basis by a broadly representative body, like the ABA committee, that can make a wide-ranging inquiry as to the necessity for and possible consequences of modification. Accordingly, we decline acceptance of the Government’s proposal.
The judgment of appellant’s conviction is reversed, and the case is remanded to the District Court for such further proceedings, if any, as may be consistent with this opinion.

§ 5.4 Length of Deliberations; deadlocked jury.
(a) Before the jury retires for deliberation, the court may give an instruction which informs the jury:
(i) that in order to return a verdict, each juror must agree thereto;
(ii) that jurors have a duty to consult with one another and to deliberate with a view to reaching an agreement, if it can be done without violence to individual judgment;
(iii) that each juror must decide the. case for himself, but only after an impartial consideration of the evidence with his fellow jurors ;
(iv) that in the course of deliberations, a juror should not hestitate to reexamine his own views and change his opinion if convinced it is erroneous; and
(v) that no juror should surrender his honest conviction as to the weight or effect of the evidence solely because of the opinion of his fellow jurors, or for the mere purpose of returning a verdict.
(b) If it appears to the court that the jury has been unable to agree, the court may require the jury to continue their deliberations and may give or repeat an instruction as provided in subsection (a). The court shall not require or threaten to require the jury to deliberate for an unreasonabe lenghth of time or for unreasonable intervals.
(c) The jury may be discharged without having agreed upon a verdict if it appears that there is no reasonable probability of agreement.
. W. Jlathes, Jury Instructions and Forms for Federal Criminal Cases, Instruction 8.11, 27 F.R.D. 39, 97-98 (1909) :
The verdict must represent the considered judgment of each juror. In order to return a verdict, it is necessary that each juror agree thereto. Your verdict must be unanimous.
It is your duty, as jurors, to consult with one another and to deliberate with a view to reaching an agreement, if you can do so without violence to individual judgment. Each of you must decide the case for yourself, but do so only after an impartial consideration of the evidence with your fellow jurors. In the course of your deliberations, do not hesitate to reexamine your own views *1185and change your opinion if convinced it is erroneous. But do not surrender your honest conviction as to the weight or effect of evidence solely because of the opinion of your fellow jurors, or for the mere purpose of returning a verdict.
You are not partisans. You are judges — judges of the facts. Your sole interest is to ascertain the truth from the evidence in the case.

"When and wherever its use is called into question it must stand or fall upon the facts and circumstances of each particular case. It has given, and wo believe each use will give us, harassment and distress in the administration of justice. No rule of thumb can circumscribe definite bounds of when and where, or under what circumstances it should be given or refused.

. The record discloses that after appellant was apprehended in his bedroom, Drayton, the victim, was brought in, and that he there identified appellant as one of his assailants. This one-man showup occurred about 24 hours after the crimes were committed, and no special necessity for a showup at that time or place appears, nor is there any indication that appellant had counsel or was warned that he had a right to counsel. At the trial, Drayton identified appellant from the witness stand, and testified to his earlier identification at appellant’s house. The showup occurred after the decisions in United States v. Wade, 388 U.S. 218, 87 S.Ct. 1926, 18 L.Ed.2d 1149 (1967), and Gilbert v. California, 388 U.S. 263, 87 S.Ct. 1951, 18 L.Ed.2d 1178 (1967), and in any event might call for careful judicial scrutiny under Stovall v. Denno, 388 U.S. 293, 87 S.Ct. 1967, 18 L.Ed.2d 1199 (1967).
. The question was raised at appellant’s trial, but not on this appeal. But see Fed.R.Crim.P. 52(b). The record presently before us in incomplete on that score and we could not now explore the question without first remanding for amplification. E. g., Sera-Leyva v. United *1187States, 133 U.S.App.D.C. 125, 127, 409 F.2d 160, 162 (1969) ; Wright v. United States, 131 U.S.App.D.C. 279, 284, 404 F.2d 1256, 1261 (1968).
. As we have stated, text supra, at note 2, appellant was sentenced under the provisions of 18 U.S.C. § 5010(b) (1964). It appears that lack of a prior adult record influenced the decision making possible his early conditional release from confinement.
. Like the Seventh Circuit, “[w]e perceive no distinction between criminal and civil cases,” United States v. Brown, supra note 51, 411 F.2d at 934 n. 4, and our ruling applies equally to both.

. As we made clear in United States v. Johnson, supra note 23, 139 U.S.App.D.C. at 200, 432 F.2d at 633, the ABA standard does not bar the use of Allen-type charges, either before or after deadlock, but only eliminates the “majority-minority” element from the usual Allen, text. And since, as we noted in Johnson, 139 U.S.App.D.C. at 200, 432 F.2d at 633, many trial judges have long since discarded this element, a uniform ban on its use would not make as much of a change as might be thought. Moreover, as Johnson also points out, 139 U.S.App.D.C. at 200 and n. 10, 432 F.2d at 633 and n. 10, references to possible retrial in the event of a hung jury, sometimes included in Allen renditions but omitted from the ABA model, do not appear in the charge as approved by the Supreme Court in Allen.

. In Fulwood v. United States, supra note 18, it was observed that “considerable *1188work for this court would be eliminated if District Judges would consistently use a form of instruction plainly within Allen." 125 U.S.App.D.C. at 180, 3G9 F.2d at 963. The cases which have subsequently come before this court attest vividly the fact that this has not been done. And, of course, adherence even precisely to the charge as approved in Allen would not alone solve the problem, for there would continually remain questions as to whether in the particular circumstances involved the giving of an Allen-type charge was legally warranted. See ABA Jury Standards, supra note 45, at 155-156.
. The proposal is also tantamount to a suggestion that we similarly modify the ABA standard. Comparison of tlie standard and the implementing instruction, notes 45-46, supra, demonstrates their complete congruence, and it is obviously impossible to meaningfully change the language of the instruction without effecting substantive change in the standard itself.
. The Conference action, taken in 1970, established a continuing committee to bring to the attention of the courts and other agencies concerned such of the ABA-recommended standards as the committee after study believes suitable and desirable for implementation.
