"Dearest Helena: By now, the news of our defeat has reached the Earth. The creatures we were sent here to tame are un-tamable, and the colonies we were sent to reclaim have proven to be stronger than we anticipated. Whatever you may hear about what has happened out here, know this: Alexei did not die gloriously in battle. I killed him. My pride killed him. And now my pride has consumed me as well. You will never see me again, Helena. Tell our children that I love them, and that their father died in defense of their future. Au revoir."
- DuGalle's final message to his wife, Helena(src)
After being defeated by Kerrigan, the UED Expeditionary Fleet fled towards Earth. During the retreat, Gerard typed out a farewell letter to Helena before promptly committing suicide, which detailed the defeat of the UED and revealed the truth about Alexei Stukov's death, the latter of which weighed heavily on him. The letter did not reach Helena, however, as the zerg pursued and annihilated the UED fleet.
