The Battle of Tauron shares joint status with Operation Raptor Talon as the last battle of the first Cylon War. On the last day of the war, the colony of Tauron was besieged by a Cylon invasion force. Fighting was rampant, with the Cylons appearing to have possessed air, space and ground superiority.
With at least three basestars in orbit, the Cylons sent ground forces and Raiders onto the planet's surface. Colonial military ground forces engaged in urban warfare with Centurions amidst bombed out buildings, trapping civilians (such as Helena Cain's family in the city of Hypatia) in the crossfire.
It was during this operation that the Cylons finalized an armistice with the Colonies, and instigated an immediate retreat from the surface of Tauron, as well as Colonial space (TRS: "Razor", extended version).
