The Unforgiven vs The Tau Empire (Warhammer 40k)

The Rules

• The Ethereal are found out to be working with a small enclave of the Fallen Angels. Chapter Master Azrael, and acting Supreme Grand Master of the Inner Circle is completely livid. The forces of the Unforgiven are gathered as a single unit to assault the Tau Empire and purify it in flame, and strings are pulled (AKA Inquisitorial Representative blackmailed) to get the Deathwatch to come in full force too.
• Dark Angels get any support forces they would normally have normal circumstance
• Lets include the Farsight Enclave with the Tau Empire because why not I guess. The Deathwatch won't make much of a distinction between the two
• Current versions of all
• The Tau have all their subjugated races here

If this is a stomp for the Dark Angels, the Craftworld ofSaim-Hann will assist them

The Callouts

When you say the Unforgiven, are we talking like Legion levels of strength here? If so I'd definitely back them against the Tau Empire. Obviously because they're xenos scum of course, and not because part of their Legion turned traitor I mean because they're just that loyal to the Emperor!

The Unforgiven is an organization comprised of almost every single Dark Angels Sucessor Chapter. Seeing as Dark Angels are tied with the Ultramarines for the "most stable geneseed award" and they emerged from the Heresy relatively unscathed compared to the legions decimated at Isstvan, this comprises approximately 15% of all space marine chapters in existance, and probably quite a few of the Primaris ones as well, seeing as they got preferential treatment relating to getting those, being a first founding Chapter

@decaf_wizard: Since it's basically the entire Legion I'm giving it to the Imperium, I doubt they'd even need the Deathwatch. The Tau are a minor power still even after their recent moves against the Imperial worlds closest to them, and the previous Damocles Crusade scared the hell out of them, and it wasn't even that large by crusade standards(at least when it attacked anyway). I don't think they can handle a Legion level opponent, especially one of the larger ones. The Tau have some good commanders and the added strength of Farsight but I don't think it's enough because the Deathwatch will be constantly be trying to assassinate them and the Ethereals.

Im also ruling out the Inquisition or High Lords screwing with the Dark Angels and sabotaging them or something. Its not unheard of for Space Marines to re-form legions temporarily for military engagements. Even the Ultramarines did it once to screw the Night Lords sideways

@decaf_wizard: High Lords are no more. Papa Smurf took their jobs.

Didn't he let them exist, just as like, stooges?

Also comment on the battle noob

@decaf_wizard: Nah, he disbanded them in Watchers, IIRC. Was near the end when one of the members approached the gatekeeper dude trying to set up a plan to stop Papa Smurf's free reign, but it didn't work and he just dissolved the positions.

Also, the Tau die. Which is good.
