Planetary History[edit]

Clan Invasion[edit]

Ridderkerk was conquered by Clan Wolf during Operation Revival as part of their Third Wave of attacks in July 3050, with major battles taking place at Vesinur, Sally's Bar and Grill, and Canton Downs. The 1st Lyran Regulars were suppose to defend the planet from attack, however just prior to the invasion it's commanding officer had been in a traffic accident which rendered him unconscious while his second-in-command proved incapable of commanding the RCT. Thus when the 328th Assault Cluster made it to their drop zone and began advancing on the capital they were unopposed. By the time battle was actually joined a lack of leadership and tactical control completely doomed the Lyran Regulars, who couldn't even manage to flee off-world and thus ceased to exist by the end of the day.[29]

The Jihad[edit]

Ridderkerk was the subject of a second attempted invasion in October 3071, when forces from Clan Hell's Horses invaded the Clan Wolf occupation zone in the Inner Sphere, attempting to annex planets to form their own holding in Spheroid space. Although the Hell's Horses troops assaulted the Wolf forces on Ridderkerk, they couldn't displace them for long, and Wolves counterattacked at Ridderkerk later that month.[30][31]

Dark Age[edit]

At some point between 3100 and 3130 Ridderkerk was abandoned or rendered uninhabitable.[24] [25]
