(written from a Production point of view)
With the Dominion War raging, the old Klingon warrior Kor feels left out of the action, and looks for some way to get his share of the honor of battle. However, his efforts to play a part are stymied by Martok, who holds a grudge against Kor.
Having just relived the Battle of the Alamo in a holosuite at Quark's, Dr. Bashir and Chief O'Brien heatedly discuss the fate of Davy Crockett, a legendary hero who died in the battle. O'Brien expresses his opinion that Crockett was executed by General Santa Anna as a point of pride, while Bashir believes Crockett was tired of living on his reputation and ultimately surrendered. Worf joins them and comments that if you believe in the myth of Davy Crockett, then there should be no doubt that he died a hero, but if instead you believe that Davy Crockett was just a man, it does not matter "how he died".
Worf returns to his quarters and is soon visited by Kor. The venerable Dahar master congratulates Worf on his distinguished service in the war, and commiserates on the death of Worf's wife, then admits he is there to beg a favor: Kor has lost whatever influence he once had, so the Klingon Empire has decided that there is no place for him in the war. He pleads Worf to intercede for him so that he may "end my life as I have lived it – as a warrior."
Martok unveils his new battleplan to Sisko: using only a squadron Birds-of-Prey, he will hit Dominion facilities and create chaos behind their lines, starting with an audacious raid on the heavily-fortified Dominion outpost on Trelka V. Sisko likens it to an ancient Earth tactic known as a "cavalry raid" and offers to join him with the USS Defiant. Martok politely declines, saying that the Defiant will be more useful in deterring Jem'Hadar ships that may be following once the Klingons head back to Federation-held territory.
Aboard Martok's ship, Worf tries to speak to him again about Kor. Martok explains his hatred of Kor: Martok's family came from the Ketha lowlands and had little, but had served the Empire for generations as soldiers. However Martok's father had hopes his son would be an officer in the Klingon Defense Force and eventually found someone to sponsor his application. After passing the exam on the first try, Martok's application rested on the oversight council which should have been nothing more than a formality. Kor, a member of the council, turned him down for no reason other than Martok's common background, much to the shame and embarrassment of Martok and his father. With a black mark on his record from a Dahar Master, Martok couldn't even enlist as a common soldier but was forced to spend five years as a civilian orderly aboard a ship. "Luckily" the ship was attacked by an inept Romulan vessel which allowed the young Klingon to display his courage and military skills, and then earned him a battlefield commission. To Martok though, this all happened too late, as his father had died and could not share in the honor. If Kor had had his way, he concludes, Martok would still be scrubbing decks, instead of playing the vital role in the war he now occupies. Worf said he had used his own authority to appoint Kor as Third Officer aboard a ship in the Ninth Fleet. He begins to apologize, but Martok waves him down, saying it has been done and warns Worf that he is responsible for Kor.
In the Replimat, Kor is enjoying a catch-up meal with Ezri Dax, when Worf appears. He tells Kor the reason for Martok's dislike of him, and Kor does not recall this but admits it is possible. Worf tells Kor that he should not have stopped a man from serving the Klingon Empire for such a trivial reason. Rebuffed, Kor asks if his commission was revoked. Worf confirms that it is not and instructs Kor to report for duty in the morning aboard the IKS Ch'Tang and advises him to stay out of Martok's way. Before leaving, Kor asks for a reminder of the ship's name.
Hours later, as the squadron is about to deploy, Kor reports for duty on the bridge of the Ch'Tang. With the memories of his humiliation still vivid, Martok is aggravated when every member of the bridge crew is awestruck to have a Dahar Master on board.
In Quark's bar, Ezri talks to Kira about what it was like to see Kor again, an odd experience since it's the first time Kor has seen Ezri and not Curzon. She does in part wish she could be side-by-side with him once more. Quark overhears this and assumes she meant Worf.
A brief respite of Martok telling war stories in the ship's mess hall is interrupted, when Kor joins them, and the crew is once again in awe. Noticing the tension, Worf attempts to change the subject by asking Martok to announce his plan of attack for Trelka V. Martok lays out his plan, which impresses the crew ... only for Kor, in congratulating him, to note that Kor himself had once executed a similar plan against the Federation outpost on Caleb IV, along with his late comrade Kang. As the crew turns their attention back to Kor, Martok leaves the room in disgust.
Worf attempts to reassure Martok that the crew are simply not accustomed to serving alongside a Dahar master, when an alert klaxon sounds. As the crew reports to battle stations, Kor appears confused as to where he's supposed to go, before an encounter with Lieutenant Synon, the ship's helmswoman, inadvertently reminds him he's supposed to go to the bridge.
Act Three Edit
At Trelka IV, Martok orders two of his ships, the IKS Malpara and IKS Ning'tao to decloak and fire on the planetary base, before withdrawing. This attracts the attention of a Cardassian Galor-class cruiser. The Malpara is quickly destroyed, but the Ning'tao manages to lead the larger ship out of the system.
Meanwhile, with the base's shields down and repair crews underway, Martok orders the other ships to decloak and open fire. In the heat of battle, Martok and Worf are incapacitated, leaving Kor to assume command. The confused Kor orders the ships to come around for another pass, even as an injured but conscious Martok, who had only intended one pass, attempts weakly to order his crew to withdraw. The ships are battered by returning fire from the base, with the IKS Slivin taking heavy damage and the IKS Orantho suffering a hull breach as well as the deaths of its captain and first officer.
Kor announced his intention to capture the base, despite Synon's protests that they have a garrison of ten thousand troops. When Kor orders the crew to open a channel to his long-dead comrade Kang, to tell him that Federation outpost on Caleb IV will fall within the hour, it becomes clear that the old Klingon has confused reality with his memories of a century-old battle.
The injured Martok attempts to dispose of Kor by throwing a d'k tahg at him. However, Worf, regaining consciousness, manages to catch the knife, knock Kor to the deck, and resume command, ordering an escape course. Martok then orders Kor off his bridge.
Act Four Edit
While the raid is going on, back on Deep Space 9, Quark decides, while talking to Jake, to declare himself, telling Ezri that Jadzia was too good for Worf, and Ezri most definitely is, and it would be the worst mistake for her to resume a relationship with Worf just because she feels obligated by Jadzia's commitments. Ezri cuts him off and clears the air, telling him that she and Worf have agreed to just remain friends, and not pursue another relationship. Having said that, she is still charmed by the kind, dear and [for Quark] embarrassing declaration the Ferengi just made to her. Ezri then kisses Quark on the cheek, which the Ferengi apparently sees as encouragement and amuses Jake.
Kor eats in the mess hall, alone except for Martok's elderly aide, Darok. Martok comes in, along Synon and weapons officer Kolana, who start needling him mercilessly about his senility. Kor does not respond, but finishes his meal in silence and excuses himself. Martok challenges him to make some kind of response, and Kor simply tells his fellow Klingons to enjoy the fruit of life, but not to live too long, since "the taste turns bitter" as one grows old. In the wake of his absence, Martok clearly doesn't feel the enjoyment of his long-awaited victory over Kor.
In Martok's quarters, Worf brings him the new personnel assignments. He has removed Kor from active duty, and concedes that it was a mistake to give him a position in the first place. Worf says that when they return, he will ask Chancellor Gowron to find some sinecure for Kor that will allow him to feel useful, while keeping him safely out of combat. Martok confesses that he did not take the satisfaction from gloating over Kor that he thought he would; the elderly Klingon is no longer an enemy, just an old man to be pitied, and a sobering glimpse of what awaits every Klingon who lives too long, even one of Kor's accomplishments.
The bridge officers grimly report that the Jem'Hadar will overtake them in about two hours, less time than it will take the Klingons to rendezvous with the Defiant and other Federation reinforcements. Worf devises a plan: one Bird-of-Prey, the Ning'tao with a skeleton crew, drop out of warp and fire a graviton pulse to force the Jem'Hadar to drop out of warp, and then engage them long enough for the rest of the fleet to reach safety. Since the Ning'tao's own captain is considered too inexperienced, Worf volunteers to command the doomed ship.
Kor is lying in his quarters when Darok drops in and briefs Kor on the plan in secret. Darok says the plan is a good one, but its success hinges on the one ship being able to successfully engage and delay the Jem'Hadar, to prevent them from reentering warp to resume pursuit of the fleet. Kor, despite the recent drubbing his self-confidence has taken, immediately states that the solution would be to confuse the Jem'Hadar sensors in the opening moments, with a spread of torpedoes, and Darok (clearly still a "fan" of Kor) encourages him that the ship must be commanded by a warrior of Kor's great experience – but, even more importantly, such a warrior could not hope to succeed unless he was completely confident in his own abilities. Kor, with new resolve in his heart, replies he would not take on the mission unless he was this confident. Darok bows deeply and tells Kor it has been an honor to serve with him.
Soon after, Kor catches up to Worf in the transporter room, where the two say goodbye until they meet again in Sto-vo-kor. Worf, to his surprise, is then asked if he has any message for Jadzia, but before he can respond, Kor renders him unconscious with a hypospray. Kor promises the unconscious Worf that he will convey Worf's undying love to Jadzia, and tells his friend to "live well." Beaming away to the doomed ship, Kor gives one last salute to the world he loves and the Empire he has served.
"Long live the Empire!"
In space, the Ning'tao de-cloaks as it drops to impulse, then turns about and hurtles back into warp, towards the enemy. Kor's progress is monitored by ship sensors. At this point, it is assumed by Martok and others that Worf is leading the suicide mission.
Darok brings a bottle of bloodwine to the bridge, in brazen defiance of regulations. Martok objects, and Darok says that, whether the volunteers fail or succeed, they will deserve to have their courage saluted. The bridge crew keeps a tense vigil as the Ning'tao drops out of warp and succeeds in pulling the whole Jem'Hadar squadron out of warp. The battle goes beyond their sensor range, and they can only wait. Martok expresses a hope that Worf will die gloriously – but when Worf himself appears on the bridge and states that this will not happen today, it dawns on him that Kor has taken control of the ship.
Kolana reports that the Ning'tao is taking heavy fire, but has succeeded in collapsing the Jem'Hadar formation. Then the battle goes beyong the Ch'tang's sensor range, and they lose contact. Martok ponders that it doesn't seem possible that a single Bird-of-Prey could stall ten Jem'Hadar ships, but Worf is more optimistic about the outcome.
The scene dissolves to later, when, after the whole bridge crew has waited with bated breath, Kolana reports in an awed voice that, miraculously, Kor has succeeded: the Jem'Hadar can no longer overtake the Klingon ships before they rendezvous with the Defiant. For all his own tactical brilliance, Martok is unable to comprehend how Kor could have succeeded. In reference to the Crockett discussion at the beginning of the episode, Worf simply replies, "Does it matter?" Martok demands the bottle from Darok and lifts it high in salute to Kor, "a noble warrior to the end!" As the bottle is passed around the bridge, Darok begins to sing. The rest of the bridge crew (with the exception of Martok, who still cannot bring himself to forgive Kor) joins Darok in honoring the Dahar master who has just sacrificed himself to save all their lives.
Memorable quotes Edit
"The only real question is whether you believe in the legend of Davey Crockett or not. If you do, then there should be no doubt in your mind that he died a hero's death. If you do not believe in the legend, then he was just a man, and it does not matter how he died."

- - Quark, about Ezri Dax

Story and scriptEdit
- As is hinted at in the conversation between O'Brien and Bashir in the teaser, Ronald D. Moore based this episode on the legend of Davy Crockett and the Battle of the Alamo; "Did Crockett surrender? Was he executed? Did he die on the Alamo walls, swinging his flintlock over his head? It depends on whether he's a hero or not, or if he's a legend to you. If he is, then he went out a hero. If you don't think that, then he's just another guy and it doesn't matter how he died. It felt like we could send Kor out the same way. It doesn't really matter how Kor died. It doesn't really matter what he did in those final moments of his life. What matters is the legend." (Star Trek: Deep Space Nine Companion) This notion of the legend being more important than the fact recalls the 1962 John Ford movie The Man Who Shot Liberty Valance. It also recalls the second season episode "The Homecoming", specifically the character of Li Nalas, who was based on the Jimmy Stewart character from Valance.
- Moore based the rivalry between Martok and Kor on class issues mainly due to how each actor had portrayed their respective character in the past; "John Colicos always played Kor as an aristocratic and 'to the manor born' Klingon who ruled by 'divine right'. J.G. Hertzler always made Martok seem like a guy, like a common soldier who had worked his way through the ranks. So there was a natural antipathy between the two characters." (Star Trek: Deep Space Nine Companion)
- Hertzler was able to contribute a line of dialogue in the episode: "And I got to do a tiny bit of writing in that one. I asked Ron (Moore) if I could add a line to a long speech I had at the end of the episode. I added, “Unfortunately, my father did not live to see that day.” That, for me, rounded out the character’s choice to never forgive, to take his hatred of Kor and his resentment to the grave. It was important to me to not forgive Kor on behalf of my father. They said, “People like Martok. They want to root for him.” I said, “You know, it really doesn’t matter.” As a character, as an actor it’s a lot more exciting to play that “human failure” of never forgiving than it is to forgive. You might be a better angel to forgive, but there aren’t that many angels in the Klingon nature." Hertzler named Martok's father Urthog in The Left Hand of Destiny.
- Armin Shimerman sees this episode as setting up his character for the rest of the season; "For the most part, the season is about Quark either mourning Jadzia or pursuing Ezri. The audience would never accept them as a couple though, so there was never a chance for that. So I spent most of the season crying into my own drinks, rueing the fact that I was getting nowhere with Ezri. Although everybody else on the show seemed to get somewhere with her!" (Star Trek: Deep Space Nine Companion)
- A deleted scene in this episode involved Quark sitting at the bar and lamenting his failure with Ezri, and Jake attempting to cheer him up by making him a drink. The scene would have gone between the scene where Quark hears Ezri talking about Kor and thinks she is talking about Worf, and the scene where he confronts her about her feelings. In the scene, as Quark pours out his heart to Jake, Jake is getting flustered because he is trying to concentrate on making the drink, but Quark keeps distracting him, and he keeps getting it wrong, pouring it out and having to start again. The scene was cut for time. (Star Trek: Deep Space Nine Companion - A Series Guide and Script Library)
- An extra part of the opening scene where O'Brien, Bashir and Worf discuss the Alamo was either unfilmed or deleted; in it, Bashir talks about Travis drawing the line in the dirt during the battle. (Star Trek: Deep Space Nine Companion - A Series Guide and Script Library)
- This episode is one of J. G. Hertzler's favorites. Talking about it in an interview he said, "To have the amount of profound artistry inherent in John Colicos and Neil Vipond working around you is what you live for. When you get that much experience on stage that still has the juice – that's what made that episode. Plus I had two beautiful Klingon females on either side of me. That didn't hurt!" He also comments, "It's my favorite Deep Space Nine script. It was an actor's dream. I got to really let loose my most venomous, vindictive anger at this old man, and just attack him relentlessly. I think that made some of the viewers uncomfortable, because it was hard to like Martok in those scenes, but we all do things that people don't like. It made my character three-dimensional, so I was happy." Furthermore, "I told the producers that Martok shouldn't join in singing the ballad at the end. They were worried about that, but I said, 'Listen, Martok can give Kor all the due praise, but he cannot sing to him because the hatred is still there, underneath. He does not forgive what that man did.' I thought that was more important for my character than bringing him all the way around. I wanted to leave that show unfallen." (Star Trek: Deep Space Nine Companion)
- Nancy Youngblut commented: "My work as an actor since 1982 has often meant playing tough, assertive characters, including Captain Kolana of the Ch’Tang, a Klingon commander on Star Trek: Deep Space Nine. The episode was called “Once More Unto the Breach.” I had my own ship. I loved flying my own ship". (X)
- Kor's toast to Jadzia Dax, "To absent comrades," is reminiscent of Kirk's toast of Spock in Star Trek III: The Search for Spock and Picard's toast of Data in Star Trek Nemesis, "to absent friends," which is the traditional naval toast of the day for Sunday.
- John Colicos gives his last performance as Kor in this episode. He first appeared in the role thirty-one years previously in TOS: "Errand of Mercy". This was Colicos' final acting role before his death on 6 March 2000.
- Kor is seemingly the only person, besides Captain Sisko and Jake, to have known Curzon, Jadzia and Ezri.
- The title for this episode comes from William Shakespeare's Henry V – Act III, Scene I, lines 1-34, as Henry rouses his troops before an attack on a French castle; "Once more unto the breach, dear friends, once more; Or close the wall up with our English dead. In peace there's nothing so becomes a man/As modest stillness and humility: But when the blast of war blows in our ears, Then imitate the action of the tiger; Stiffen the sinews, summon up the blood, Disguise fair nature with hard-favour'd rage; Then lend the eye a terrible aspect; Let pry through the portage of the head/Like the brass cannon; let the brow o'erwhelm it/As fearfully as doth a galled rock/O'erhang and jutty his confounded base, Swill'd with the wild and wasteful ocean. Now set the teeth and stretch the nostril wide, Hold hard the breath and bend up every spirit/To his full height. On, on, you noblest English. Whose blood is fet from fathers of war-proof! Fathers that, like so many Alexanders, Have in these parts from morn till even fought/And sheathed their swords for lack of argument: Dishonour not your mothers; now attest/That those whom you call'd fathers did beget you. Be copy now to men of grosser blood, And teach them how to war. And you, good yeoman, Whose limbs were made in England, show us here/The mettle of your pasture; let us swear/That you are worth your breeding; which I doubt not; For there is none of you so mean and base, That hath not noble lustre in your eyes. I see you stand like greyhounds in the slips, Straining upon the start. The game's afoot: Follow your spirit, and upon this charge/Cry 'God for Harry, England, and Saint George'!" This speech is generally regarded as the finest battle rousing speech in all of literature.
- This episode features the Raid on Trelka V. During the raid, the Klingons use the meter as a unit of measure instead of the usual kellicam.
- The Dominion long-range tachyon scanner would never be mentioned again.
- A script for this episode was sold off on the It's A Wrap! sale and auction on eBay. 
- Kor's speech to the younger Klingons about the sweet taste of life is reminiscent of what he said to the Organians in his first appearance: "I hope you will continue to savor the sweetness of your life."
- This episode features the very rare sight of Worf wearing his full Starfleet uniform without his baldric (near the beginning when Kor visits him in his quarters).
- The blood wine that Kor and Worf drink is "2309," the same vintage that Nog "acquired" for Martok in the previous episode, "Treachery, Faith and the Great River". Martok later shares the same vintage with Gowron in "When It Rains..." and with Sisko and Admiral Ross in "What You Leave Behind".
