Mandelfarne Island was an island on Dunbar's World.
In 5149 CE, the island was a base for Pellegrino forces invading Dunbar's World. The Pellegrinians placed an anti-ship missile battery there, making a direct assault from space or air too dangerous. An RCN assault force took over the freighter Rainha which was used to resupply the Pellegrino forces, and landed her on the island. Thereafter, the RCN forces, with Adele Mundy in the lead, attacked the base, neutralized the missile battery, and made possible the larger assault on the island and eventual RCN and Dunbar's World victory in the Battle of Dunbar's World.5:21
