Operation: Sunburst

Operation: Sunburst was a major conflict between the Brotherhood of Steel and the New California Republic taking place at HELIOS One in 2276.

Background
As part of the ongoing Brotherhood War, the NCR attacked and occupied the Brotherhood's fortifications at the HELIOS One power plant, part of "Operation: Sunburst." The plant housed the Brotherhood chapter, where the faction was attempting to refurbish the facility and bring it back online. The Brotherhood leaders knew that the location was not defensible and that despite their superior equipment and training, the NCR outnumbered them by a wide margin.

Due to these factors, when the NCR began to move in, senior paladins such as Hardin advised the chapter's leader Elder Elijah to fight a retreating action, but he refused. The elder ordered forces to defend the facility, insisting that he just needed "more time".

Despite the efforts to hold the plant, the Brotherhood forces were forced to retreat, suffered a loss of more than half of its paladins and knights, and the disappearance of Elder Elijah. The NCR consolidated their hold on the location and then set out to pursue any remaining Brotherhood forces, but found none, as the group had retreated to a nearby bunker.
