At some point, the Tau sent an expeditionary force to the planet [[Malbede]] where they came into [[Battle of Malbede|conflict]] with the [[Ultramarines]] [[Chapter]] in 936.M41. However, the world proved to be cursed when their fighting awakened the sleeping [[Necron]]s from their tomb beneath the surface. In an effort to combat this threat, the Tau and the Ultramarines combined forces to defeat the Necrons. Once the conflict was over, the Tau were allowed to evacuate their forces by [[Marneus Augustus Calgar|Marneus Calgar]] who proceeded to destroy Malbrede through an [[Exterminatus]].{{Fn|2}}

In [[M41|666.M41]], the Tau fought against the [[Space Marines|Adeptus Astartes]] of the [[Space Wolves]] [[Chapter]] during the War for Kvarium Alpha. On that water-clogged world, drop pods landed deep in the oceans where their occupants made a move to engage their enemy. On the surface, the battle was fought between the two sides with an equally deadly conflict erupting in the depths of the sea between the Space Wolves and Tau Battlesuits. [[Thunderhawk]] Gunships were used to great effect against Hammerhead tanks and Manta gunships with torpedoes, prop-bombs and missiles being used against the Tau. Ultimately, the Space Wolves proved to be the victor in the conflict where hundreds of Tau and Space Wolf corpses floated to the surface. With their mission complete, the Space Wolves made the long trek back to land across the sea bed.{{Fn|1}}
