Battle of the Great Bear

Groombridge-1830 and the battle that took place over it.

The Groombridge-1830 system was a UNSC-colonized star system, located 29.7 light years from Sol.[1] It was invaded on December 24, 2530 by the Covenant. Admiral Preston Cole's fleet responded, defeating the Covenant Fleet, but taking heavy casualties during the battle. The colony's fate, whether it was glassed or not, and the state of any survivors, is unknown.[2]
