SISKO: An outbreak of Rudellian plague has struck the Cardassian colony on Pentath Three. The Cardassians are preparing several convoys of medical supplies and relief workers, but the Pentath system borders Klingon territory and the Cardassians are worried about raids.
WORF: Well, Pentath is a strategically important system. The Klingons will try to stop them.
SISKO: Now the problem is the Cardassians don't have enough warships available to protect the relief convoy. They've asked for Starfleet protection, and because of the humanitarian nature of the request, we've agreed. There will be seven convoys headed for Pentath Three in the next week, each of them protected by a Federation starship. The Defiant has been assigned to escort convoy six, and I've chosen you to be in command.
O'BRIEN: (to camera) There were two Klingon ships. A bird of prey and an old battle cruiser. One would engage us while the other went after the convoy, then they'd switch, the first ship going after the Cardassians while the second ship came after us.
(BOOM)
KIRA: We've lost the number three starboard shield.
WORF: Come about. The cruiser is taking us too far away from the convoy. Try to keep our portside to the Klingons.
O'BRIEN: Aye, sir. This went on for, I don't know, maybe five minutes. They'd come at us, try to draw us away from the Cardassians, we'd head back. Then the bird of prey came toward us off the port bow.
(BOOM)
KIRA: I have phaser lock.
WORF: Fire!
(They hit the ship and it cloaks.)
KIRA: We damaged them, but not much.
O'BRIEN: We'd seen them do this cloak and run manoeuvre a few times, and Commander Worf thought he saw a pattern.
WORF: We have them now. Come to course one eight five mark two seven eight. Stand by quantum torpedoes, full spread.
KIRA: Aye, sir.
O'BRIEN: I ran a quick sensor sweep and then I reported. I'm picking up a tachyon surge directly ahead.
WORF: Fire!
CH'POK: Let's say... You're in command... Do you fire?
O'BRIEN: No.
Let me get this straight. You’re in a battle, outnumbered two-to-one, fighting for the survival of your ship, a civilian medical convoy, and the colony on Pentath III. The enemy is using a (cowardly and dishonorable) tactic of decloaking, attacking, and cloaking again before your counterattack. You detect a pattern in the enemy’s movements and anticipate the location where he will appear next. You head for that location and take aim. As you anticipated, a ship begins to decloak...SISKO: That was your first mistake. What was your second?
WORF: When the ship decloaked, I should have checked the target before I fired.
SISKO: You're damned right you should've checked.
...and you’re supposed to hold your fire just in case a civilian transport wandered into the battlespace and decided to decloak right in front of you in the exact spot where your analysis predicts the enemy BoP will appear?
And how could the Klingon Empire, with a straight face, even ask for the extradition of Worf for the crime of accidentally shooting a civilian ship in a battle in which the Klingon military was deliberately targeting civilians?!!! How is this incident supposed to make the Federation look bad and not the Klingons?
