As an Ultramarines Successor Chapter, they are fanatic followers of the Codex Astartes. Most of their history is not known with only partial records of the 41st Millennium available. That said... the Chapter's companies appear to be involved in all sorts of actions. In none of those actions are they able to keep their shit together, as every known engagement has them fielding but a single company and getting outnumbered with predictable results.
Founded in the 36th Millennium from Roboute Guilliman's Gene-seed.
- Battle of Archimedon - The Chapter's 3rd company was deployed to Archimedon. Their mission was to defend a spaceport on the planet. However, after the company suffered heavy losses, they destroyed the spaceport themselves rather than let it fall into enemy hands. The Chapter Master didn't approve of it, but refrained from censuring the company. Instead, he sent them to fight a gruelling campaign in Helmabad, which leads us to...
- Helmabad Rebellion - The 3rd company was given the opportunity to redeem itself fighting against Chaos Cults, where they spent months dealing with non-stop fighting and the unprofessional PDF. But when the Captain learned from the company's Librarian that Helmabad was mere hours away from a full scale Demonic invasion, he got cold feet. Deciding that dying for the Emperor wasn't its own reward, he proposed abandoning the doomed world. The Chaplain obviously wasn't on board and had to be killed along with the rest of the loyal Marines. Not only that, but the Captain turned on the PDF to take the Planetary Governor hostage and turned him over to the Chaos Cults as a bargaining chip to secure safe passage off-world. The remains of the 3rd company, knowing well what they had done, decided to set course for the Eye of Terror.
- Liberation of Antillis IV - A company of the Chapter gets overwhelmed by forces of the Black Legion. They fight to the last and detonate their position before being overrun. Their sacrifice was not entirely in vain however, as the larger campaign to retake Antillius was won by the Imperium, and a single Scout survived with a Thunderhawk containing much of the Gene-seed lost during that battle.
- Taros Campaign - The desert world of Taros gets investigated by the Administratum, as its tithe and production estimates are out-of-date. The delegation finds that, while Taros is meeting its quotas to the local Forge World, it seemed to be mining much more without growing its stockpiles beacause the Planetary Governor had been cutting a deal with the Tau. The Chapter's second company answered the request for punitive action against Taros and assaulted the Governor's palace... only to find he had already been evacuated by the Xenos. The Tau forces on the planet quickly converged upon the Astartes and kept them pinned down for two days before the Avenging Sons finally decided to evacuate. This failure to slay the treacherous Governor would set the stage for the following invasion of Taros, and its eventual failure.

The Chapter appears inclined to send their forces in Company strength to fight all enemies of The Emperor, which clearly hasn't been working for them in recent years.
