'''Battle Group 4''' was a [[Battle group|formation]] of the [[Colonial Military Administration]]'s [[fleet]], under the command of [[Captain (Navy)|Captain]] [[Maribeau Veredi]].<ref name="gc rb7"/><ref name="he459"/><ref name="for118"/> The battle group was assembled and dispatched to investigate the loss of communications with the [[human]] [[Outer Colony]] of [[Harvest]]. Upon arriving at the planet on [[2525#October|October 7, 2525]], Battle Group 4 encountered a [[Covenant super-destroyer]], leading to one of the [[First Battle of Harvest|first naval engagements]] of the [[Human-Covenant War]].<ref name="Genesis">''[[Halo Wars: Genesis]]''</ref><ref name="ENC">'''[[Halo Encyclopedia]]''', ''page 36'' (2011)</ref>

{{Quote|The Colonial Military Administration sent a battle group to respond to the alien threat. They survived less than fourteen seconds before two of the three destroyers  [sic] in the group were obliterated, and the remaining destroyer, the Heracles, was forced to retreat.|[[Codename: SURGEON]]'s report, ''[[Historical/Psychological Analysis of Cole, Preston J.]]''<ref name="he459"/>}}

After communications were lost with the [[Unified Earth Government]] [[Outer Colony]] of [[Harvest]], the [[Colonial Military Administration]] deployed the unarmed scout ship {{CMAShip|Argo}} to investigate. ''Argo'' arrived over Harvest in the [[Epsilon Indi system]] on [[2525#April|April 20, 2525]], but contact was lost with the scout ship shortly after.<ref name="timeline"/><ref name="for118"/> In response, fearing that [[insurrectionist]] forces had taken control of Harvest and unaware of the true nature of the enemy,<ref>'''[[Halo Mythos]]''', ''page 63''</ref> the CMA and [[UNSC Fleet Command]] assembled Battle Group 4—consisting of the [[Hillsborough-class destroyer|destroyer]] {{CMAShip|Heracles}} and the [[Charon-class light frigate|frigates]] ''[[CMA Arabia|Arabia]]'' and ''[[CMA Vostok|Vostok]]''—to investigate Harvest, led by [[Captain]] [[Maribeau Veredi]].<ref name="timeline"/><ref name="for118"/>

When the battle group arrived over Harvest on [[2525#October|October 7, 2525]], they discovered that the planet's surface was partially [[Glassing|glassed]] and detected the [[Covenant]] [[Covenant super-destroyer|super-destroyer]] responsible for the massacre of Harvest and destruction of ''Argo''. Veredi followed first-contact protocols by attempting to initiate communications with the ship, but the Covenant super-destroyer suddenly opened fire upon the battle group with its [[pulse laser turret]]s. The battle group returned fire, but their [[Archer missile]]s had no apparent effect. In fourteen seconds, ''Arabia'' and ''Vostok'' were destroyed—lost with all hands—and ''Heracles'' was severely damaged.<ref name="for118"/><ref name="Genesis"/><ref name="site timeline">[http://www.halowars.com/gameinfo/timeline2.aspx '''Official Halo Wars Community Site''': ''Timeline'']</ref>
