Desolation Island (place)
From WikiPOBia
Desolation Island is an island in the south Indian Ocean which appears in Desolation Island as a refuge where Jack Aubrey manages to bring HMS Leopard to be repaired. It strongly resembles Kerguelen Island and the latitude and longitude mentioned in the book is very close to Kerguelen. However, in The Thirteen-Gun Salute Aubrey specifically states that "our Desolation island" is not the same as Kerguelen.
