Battle of DM-3-1123 b

"Enemy forces lacked basic cohesion but quickly gained numerical superiority."

The Battle of DM-3-1123 b was a ground and naval battle in the Forerunner-Flood War.

The Flood attacked the planet with 149 captured non-military (Civilian or private commercials) Forerunner vessels, and while the Forerunner Naval Defence was able to destroy all the Flood vessels, the sole intent of the Flood was not to fight an orbital battle, but rather to land on the surface and disperse their forces to infest the local Forerunner population. While disorganized and lacking Unit Cohesion, the sheer number of Flood overwhelmed the Forerunner ground forces, and within 32 hours, the Forerunner fleet in orbit evacuated all population centers that had not yet been engaged by the Flood attack, and bombarded the planet from orbit, completely destroying the biosphere of DM-3-1123 b, and destroying all Flood forces on the ground. The Forerunner evacuation was able to save well over one million people, but this only amounted to ~.0006% of the population, which totaled more than 2.25 billion.
