The Barbarians: A Soldier's New Guinea Diary is a 1988 memoir/novel by Peter Pinney based on his experiences in World War Two recorded in his diary in 1943.
It was followed by other accounts of Pinney's war service, The Glass Cannon (set in Bougainville in 1944) and The Devil's Garden (in the Solomons in 1945). The books make up a trilogy.
Army magazine said it "would have to rate as one of the best fictional accounts of a Diggers experience in any war and is highly recommended."
The Sydney Morning Herald wrote "rather than accounts of heroic deeds and remarkable achievements this very personal memoir includes the pettiness and waste, the antagonism of the men towards some of their officers, the waiting and the bloody mindedness."
