Battles of the Ultramarines

As taken from Codex Space Marines 5th Edition

• 745.M41 - The Tyranids enter the galaxy and the Tyrannic Wars begin. Hive Fleet Behehmoth descends upon the realm of Ultramar, laying waste to several planets. Only by the valour and determination of the Ultramarines is the threat of Behemoth ended, though the cost is high.

• 762.M41 - Marneus Calgar leads the remnants of his Chapter against the Daemon-corrupted forge world of Thrax. Under the leadership of their Chapter Master, the Ultramarines banish countless thousands of Daemons and recover crucial data-records from the twisted manufactorum complexes. With the mission complete, Calgar issues the order for Exterminatus.

• 797.M41 - The Siege of Zalathras. Marneus Calgar, Chapter Master of the Ultramarines, holds the gate alone against the greenskin horde for a night and a day.

• 799.M41 - The Ultramarines begin to fortify the eastern bounds of their realm against the emergent forces of the upstart Tau Empire.

• 805.M41 - Waaagh! Gutshredda rampages through the Forgoil system. Marneus Calgar leads three companies to the assistance of the Forgoil Planetary Defense Forces. In a little more than three weeks, the Ultramarines destroy the tellyporta ships and Stompa factories that provided Waaagh! Gutshredda with much of its momentum. In the final battle of the war, Calgar and his Terminator-armoured retinue board and destroy Gutshredda's flagship, Da Supadestructa.

• 815.M41 - Contact is lost with Explorator Fleet 913. The Ultramarines send three companies to investigate, but find only empty vessels drifting in deep space.

• 849.M41 - Brother Captain Cato Sicarius is appointed as High Suzerain of Ultramar.

• 855.M41 - Assault on Black Reach. The Ultramarines 2nd Company defeats Waaagh! Zanzag.

• 861.M41 - Chapter records indicate that the Ultramarines have finally replaced the losses incurred during the Battle for Macragge.

• 878.M41 - Chaos pirates, led by the Daemon Prince M'kar the Reborn, claim several uninhabited worlds on the borders of Ultramar. In a decisive battle in the Halamar Rift, Captain Sicarius destroys much of the pirate fleet, although M'kar the Reborn escapes into the Warp.

• 888.M41 - The Battle of the Sepulchre. Eldar from the Alaitoc and Iyanded Craftworlds assault the planet Commrath. For the first time since the Battle for Macragge, Marneus Calgar leads the entire Ultramarines Chapter to war. At the pivotal Battle for Orar's Sepulchre, Calgar defeats the Alaitoc Avatar in single combat, breaking the spirit of the surviving invaders.
