"Definite signs of battle. Destroyed Alliance corvette crashed nearby on the surface; presence of geth frigate on surface. Geth flagship was here but is now gone; noticable scorch marks on the ground. Possibility of survivors slim."

— Marcus L. Shepard observing the readouts from the colony

The Battle of Feros was a two-phase military engagement between the colonists of the Zhu's Hope colony backed by ExoGeni security and the forces of the geth heretics that occurred on June 20, 2183 CE during the Eden Prime War. Later, during phase two, a small squad from the SSV Normandy assisted the colonists and ExoGeni.
