The Battle at Boreth involved Kelpien, Ba'ul, Klingon, Section 31, and Starfleet forces, and was recorded from countless different angles by ship, shuttle, and drone sensors. It may very well be the most thoroughly documented event in Star Trek canon - better than the Battle of The Binary Stars. Apparently Starfleet took a vow to never speak of the incident, which explains why Spock never talks about his sister in TOS.


How many other witnesses know that Discovery was not destroyed?

It seems Starfleet just lost a top-secret prototype research vessel which can travel anywhere in the universe - and even to other universes - and all they do to find out what happened to it is ask 5 crew members, "Was it destroyed?" They do not seem at all concerned that Discovery could possibly have fallen into Klingon or Kaminari hands. Seriously, it was handled like someone just said their child lost a teddy bear in the mall. The evidence was overwhelming - from the massive tachyon burst the temporal rift caused, the complete lack of debris, and hundreds of sensor logs. But more important, the eye-witnesses! How many?

We have to ask if Starfleet even cares what happened to their secret vessel.

  • Starfleet knew enough of what happened re: the time suit, and they [Starfleet] have three extremely well thought of officers [Pike, Number One, Spock] saying what happened. The officers say the ship exploded as a result of all this craziness. So - don't talk about the craziness: ever, and too bad about the ship. Also - remember...."Vulcans cannot lie" is taken as a fact by many humans.

    That might work if there was very limited other evidence. Testimony is always a last resort, they certainly had Enterprise logs showing an event horizon forming. Well, that's a different question. Federation has a good reason to make this go away. But this is about how much hush-money they needed to bury this not-so-little war.

  • yeah...don't discount what the combined efforts of what Spock, Pike and Number One could do to manipulate any data

  • It seems naive to suggest they would not be investigating. Just because it didn't happen on screen doesn't mean it didn't happen. That would be it's own "treasure hunt" story arc, so it's not included in the show. Per the soap opera rule, of course it will come back from the dead to haunt the living.

1 Answer 1


The list seems to be

  • The bridge crew of USS Enterprise. We never see any non-bridge members interviewed, and given how badly damaged she was, it's likely they could claim they were occupied elsewhere if they did actually know.
  • Ashe Tyler and L'Rell (plus however many Klingons saw it)
  • Siranna (Saru's sister)
  • Me Hani Ika Hali Ka Po

Presumably all the Section 31 ships were destroyed. The Klingons had no reason to divulge they were there, let alone that they helped the Federation. Siranna's situation is unknown, but it is probable that Saru let her know what he was about to do. Po is the ruler of her world, and diplomatic immunity applies. Ashe Tyler has no reason to tell them what happened either. It's likely that Pike brought him back to Earth as well.

We have to ask if Starfleet even cares what happened to their secret vessel.

Control was wholly a Starfleet invention. And that was a ton of ships they lost. If you dig too deeply into this, there's a chance others will dig deeply as well. It would not go well for the Federation to admit they accidentally created a homicidal AI that would have eventually succeeded in exterminating all sentient life in the quadrant. And you might not want to admit Control or Section 31 ever existed either.

Better to let Discovery go and accept the official cover story than to have others asking serious questions.

EDIT: Star Trek: Strange New Worlds expounds a bit on this in S1E1 Strange New Worlds

Pike asks what happened, as the Kileys were clearly not ready for first contact. Una glances at La'an for a moment, saying she was not cleared, but Pike dismisses that, asking how they got warp capabilility. Una replies that they had given it to them, during that final battle near Xahea, when Burnham opened the wormhole that sent her and the Discovery through to the future. They were less than one light-year out from the zero point of the wormhole, and between the Klingon ships and the Ba'ul fighters flown by the Kelpiens, there were more than a hundred warp signatures. Pike realizes the Kileys' telescopes would have been just powerful enough to detect all of it, and collected enough data to reverse-engineer a matter-antimatter reactor.

What's fascinating is how this plays out

Pike breaks the Prime Directive by deliberately revealing himself and the Enterprise to the Kileys. Robert April explains he was able to keep them out of trouble by "pulling strings" to find out what really happened. Because the Federation Council could not acknowledge the Discovery wormhole, they drop the whole incident.

In other words, the event is a bit better known than Discovery S2 let on.
