Martok states that the Klingon high council supplied the Maquis with 30 cloaking devices. At the end, Sisko expresses a hypothesis that there were other Maquis survivors in addition to Eddington's group. There is a chance that some of the cloaking devices were installed in the Maquis' smaller ships, making them less likely to be detected by the Jem'Hadar.
The shot of the starbase where Eddington is being held is re-used stock footage of the space station from Star Trek II: The Wrath Of Khan.
Martok: You are either very brave, or very stupid, Ferengi!
Nog: Probably a little of both.
Martok: (Laughing) Indeed. Courage comes in all . (Pointing to his missing eye) But don't tempt fate.
Sisko: (after Nog complains that Klingons ignore him as a security officer) The next time the Klingons refuse to acknowledge your presence, do what a Klingon would do. Confront them about it! If you stand up to them, you'll earn their respect.
Jake: (laughing) Or get your butt kicked, one or the other.
Sisko: Either way, they'll never ignore you again.
Eddington: Attacking two Jem'Hadar soldiers with a pipe. That's a brilliant plan.
Sisko: It could be worse.
Eddington: I know. It could be me holding the pipe.
Eddington: The Maquis won its greatest victories under my leadership.
Sisko: Your leadership. Your shining moment of glory. Michael Eddington gets to take off his gold uniform and play hero. Isn't that wat you always wanted? To lead troops in a glorious cause? Well, you had your chance. And look were you led them: right into their graves.
Quark: I might have done a little harmless theorizing.
Bashir: About what?
Quark: Oh... something like... it was only a matter of time before the Dominion launched a full-scale assault against the Federation, and when that happened, the station would undoubtedly be their first target... And I might have idly suggested that there wasn't a chance in hell that any of us would get out of here alive.
Odo: And that's when Morn hit you with a bar stool and ran onto the Promenade screaming 'we're all doomed!'?
Quark: Some people just don't react well to stress.
Sisko overrides the safeties on the engines with access code "Sisko A-4-7-1". Writer Joe Menosky began including references to the number 47 in almost every episode of Star Trek since season four of The Next Generation. It is an in-joke, referring to The 47 Society at Pomona College in California, a college which Menosky attended.
This is the last Deep Space Nine episode to mention the Maquis. They were apparently wiped out after Cardassia joined the Dominion.
Michael Eddington dies in this episode.
We learn on this episode that Lt. Commander Calvin Hudson was killed.
Eddington once owned a coin called a "loonie". A loonie is the common name for the Canadian dollar coin which features Queen Elizabeth II on one side and a Candian loon on the other (hence the name). The implication, here is that Eddington is Canadian.
The Sand Pebbles
The ending of the episode (Eddington's death) is reminiscent of Steve McQueen's death in the film The Sand Pebbles. In that film, McQueen, injured, remains behind fighting in order to allow his crew and some civilian missionaries to escape from China, which was in the midst of a civil war between factions led by Mao Zedong and Chiang Kai-shek.
