The Liberation of Blackgard is a military engagement in the Fourth Border Wars. It is part of the Blackgard campaign to liberate the Borderlands from Keller occupation.

Following the weakening of House Keller's hold on Blackgard, Trevyr Blackgard, along with his most trusted companions, sneak into Tylan Keller's bed chamber in the night and assassinate him. Shortly after, Wylde and Dayne forces march onto Blackgard and kill the remaining Keller soldiers, recapturing the city and turning it over to Blackgard control once again.
