Battle of Asmara
From Halopedia, the Halo wiki
The fighting on Asmara is noted to have been particularly brutal, with Gage Yevgenny's fireteam of Orbital Drop Shock Troopers seeing some of the worst of the conflict. At one point in the battle, Mason and ten other ODSTs were killed by a energy sword-wielding Elite before Yevgenny stopped its rampage with a near point-blank shot from a rocket launcher.
Ultimately, the United Nations Space Command's efforts to defend Asmara proved futile, and the planet was glassed. The Assembly reported that Asmara had been lost prior to the beginning of 2530.[Note 2]
