Ultramarines came close to extinction but survived due to the courrage and tenacity of the First Company.

I remember reading a while back that the fleets of Tyranid have devouered some planets that had Space Marine fortress monasteries on them. I taught those were the Silver Skulls and the Howling Gryphones but a Quick Google disproved me. Is there a list of all the Space Marine chapters lost to Kraken/Leviathan??

According to the 40k wikia on Space Marine chapters, the following were completely wiped out or devastated by a tyranid Hive Fleet or tyranids in general :

  • I'm nitpicking of course, but afaik, the Lamenters have only gone missing. Although they went missing with only 3 companies left, so yeah, they were pretty much done for already. Nevertheless, I doubt GW would such an illustrous chapter get eradicated.
