Battle of Durisdeer

The Battle of Durisdeer, occurring in June 2531, was an engagement above the colony world of Durisdeer. The UNSC Navy, in the face of superior numbers, sought to hold off the invasion long enough for Durisdeer's population to escape. However, the planet was glassed from orbit following a brief orbital battle, in which UNSC forces were annihilated. Most of the colony's population had yet to escape the planet, or were intercepted and destroyed in the attempt to leave the system.
