The Solstice Massacre was a war crime that took place during the Barrayaran conquest of the planet Komarr. The two hundred Komarran Counselors that made up the planet's legislature surrendered on terms to Admiral Aral Vorkosigan and were held in a gymnasium in the capital dome of Solstice. On the orders of Vorkosigan's political officer, they were shot by Barrayaran security forces. Rebecca Galen, Ser Galen's sister and Duv Galeni's aunt, was among the Counselors killed.
