Liberation of Lagan
The Liberation of Lagan took place in 989999.M41.[1]
Conducted by the Ultramarines 3rd Company under Captain Mikael Fabian, the Astartes forces managed to liberate the Lagan System from the control of the T'au Empire. However, even while they managed to score this victory, several key nearby planets in the neighbouring Dolmac System willingly capitulated to T'au Water Caste ambassadors.[1]
