Dagoola IV Top Security Prison Camp 3 was the full name of the prisoner-of-war camp on Dagoola IV that held 10,000 Marilacans prisoner until Miles Vorkosigan and the Dendarii Free Mercenary Fleet came to their rescue. Within the circle, there was no sort of organized grouping and prisoners-of-war were left to themselves; the groupings that existed among the prisoners mostly took the form of people who worked together for protection. Prisoners-of-war were marked by a poisoned tattoo which was kept at bay by a field generated by the dome. This ensured that any prisoner who escaped would soon die.
