John King Davis participated in three epochal Antarctic expeditions as 1) Chief Officer of Shackleton’s Nimrod expedition in 1907, 2) as Mawson’s Second in Command and Master of the Aurora in 1911, and 3) he commanded the Ross Sea Relief Expedition in search of Shackleton’s transcontinental party stranded on Ross Island in 1916. Covering his many other assignments before and after, Davis gives a comprehensive autobiography of his career. He is a fine but not dramatic story teller who handles the crises of his expeditions with a certain detachment. He speaks of loneliness but not with how it was relieved, and therefore little about reading. His descriptions of preliminary planning for voyages is particularly good.
