Clan Ghost Bear landed on Holmsbu in March 3050. Defending the world were the Seventh and Eighth Corrugated Lancers - 2 armored regiments supported by infantry. The Lancers were ill-prepared for a fight with battle-armored Elementals and fell quickly to the Clan troops' superior weapons and training. The Ghost Bears readily accepted the Lancers' surrender.
 During the Ghost Bear invasion, the infamous Black Omen mercenaries - jumped at the opportunity to gain some retribution against their old enemies. From Wolcott, the Omen secretly penetrated the Dominion and waged a McCarron’s-style campaign against the worlds of Pinnacle, Holmsbu, and Thule, disabling each planet’s HPG and destroying munitions depots along the way.
