Editing Timeline of the Battle for Earth

{{Era|HCW}}
This is a '''timeline of the events slightly before, during, and slightly after the [[Battle for Earth]]'''. The Battle for Earth lasted between [[2552#October|October 20]] and somewhere around [[2552#December|December 3, 2552]] or possibly after the later, though notable skirmishes and engagements took place before and after this timeframe. Concurrently with these events, many battles, notably the [[Battle of Installation 05]] and [[Onyx Conflict]], were taking place.
