This question is inspired by this one, specifically the part where it says,

According to various sources there were over 2,379,000 people on board the original Death Star when it exploded.

Were the Rebels aware of the number of people on the Death Star before the Battle of Yavin?

    What choice did they have even if they knew? Or are you argueing, "that any independent contractors who were working on the uncompleted Death Star were innocent victims"?

    @Ghanima There is no argument presented in the question. It is simply a question. +1, btw. Nov 17, 2015 at 19:34
  • Praxis, I do know that. Did I write something to discredit the question?

  • @Ghanima : You asked me a question: "are you arguing...?" My answer is that I'm not arguing anything. That's all. :-)

If the Rebels knew how many people were on the Death Star, it would probably have been from the stolen Death Star plans. I haven't been able to find anything definitive, in part because there are so many stories about how the Rebels acquired the Death Star plans. We might get a more definitive answer once Rogue One comes out.

That said, the Rebels did acquire the Death Star plans with enough detail to reveal the battle station's thermal exhaust port weakness (which was only two meters wide). It would be rather odd for these plans to include such details without providing at least a rough estimate of the required crew for the Death Star (e.g. for manning all the defenses). The Rebels could probably also estimate the number of personnel from these plans even if an exact figure wasn't given in the plans.

Additionally, recall that R2-D2 hacked into the Death Star's computers in order to shut down the trash compactor that was about to crush Luke, Leia, Han, and Chewbacca. R2 may have acquired figures for the number of personnel while hacking the computer.

The Rebels probably didn't know the exact number of people on the Death Star, but between the Death Star plans and R2's hacking they probably had a rough estimate.


New Canon:

Lost Stars

"Obviously, the Rebel Alliance was no better; it had blown up the Death Star with nearly two million people on board"

This does not indicate whether the Rebels knew that number or not, just that the number was exceptionally high. Once has to presume that given the size and scope of the installation, they had some idea of the resources needed to support it.

    Attacking and destroying a military weapon/base is acceptable in times of war, is it not? There is no gray area here, the Death Star was as much a military weapon as a modern nuclear submarine or an aircraft carrier; attacking those in times of war is deemed valid.

  • @AndresF. Those are our modern rules of war. For most of history, they were far more lax. Who knows what rules they used long ago in a galaxy far, far away? :-) Dec 5, 2023 at 21:59

    Destroying the Death Star was a response to the Empire destroying Alderaan. If there were rules for war that might protect the Death Star, it wasn't the Rebellion that threw them out. Dec 5, 2023 at 22:35
  • @CristobolPolychronopolis if they are more lax, this means more targets are valid, not fewer. Plus, "terrorism" only makes sense in this galaxy; if they are using the concept, they must adhere to our standards, which is that destroying planet-killing battle stations with "Death" in their names is not an act of terrorism.

Unfortunately, the information in your question is no longer correct. The only canonical reference for the rebel estimates of Death Star casualties, as far as I know, is the new novel Star Wars: Bloodline.

“Don’t misunderstand me. Obviously the Rebellion was right to oppose Palpatine. Something had to be done. But if you ask me, that hardly condones the terrorist tactics of the Rebel Alliance.”

“Terrorist tactics?”

Casterfo stopped mid-pace; the two of them now stood in the heart of one of the long, dark tunnels, the wind rippling their robes and chilling Leia to the bone. He said, “Destroying the Death Stars, for a death toll of nearly one and a half million people, the vast majority of whom were low-level Imperial officers or even civilian workers?"

    In the real world, placing weapons in the midst of civilian populations is a terrorist tactic.

    "Lost Stars" puts the number near 2 million

    @NKCampbell - "Nearly 2 million" and "nearly 1.5 million" might reflect the same figure with different amounts of exaggeration.

    Terrorist tactics? Weren't the death stars military bases (huuge ones, but still) also used for punitive actions/genocide in a conflict? It makes them a legitimate military object to be targeted by the rebel army (or any army...) according to international law. But maybe 'terrorism' has other meaning in a different galaxy...

    Terrorism means what the speaker wants it to mean. It has to be one of the most abused words of our time. Ultimately, it means that you don't like the people you're describing with it and you want other people not to like them either.
