This painting depicts what is largely seen as the turning point of the Great Pacification: the moment the Vanguard ripped through the sky and tore into the flank of the Eleventh UN Marine Division at the Battle of Barstow. Unaware up to that point of the Vanguard’s portal technology, the Marines were totally unprepared for the assault and they were decimated by the jaws and bullets of the radiosaurs within minutes. While the conflict would officially continue for another year, many see this as the defeat that broke the UN’s military coalition and with that any hope of a bilateral peace agreement between humans and radiosaurs.
