During the subsequent [[Horus Heresy]], the Sol System was the site of bitter fighting between loyalists and traitors during the [[Schism of Mars]] and [[Solar War]]. At the final phase of the war [[Horus]]' forces succeeded in capturing the Sol System and besieged Terra itself, but were eventually defeated and repelled during the [[Great Scouring]]. Since that time, the Sol System has not been the site of all-out war though it did see fighting during the [[War of the Beast]]{{Fn|9}}, [[Age of Apostasy]]{{Fn|10}}, and recently the [[Battle of Lion's Gate]].{{Fn|11}} The System was also saw a minor but mysterious [[Necron]] raid on Mars in late [[M41]].{{Fn|12}}
