Based on recently released wartime files, interviews with surviving veterans and previously unpublished private papers, this is the incredible story of the origins and operations of a wartime special forces unit that defied the odds. Z Special Unit, one of the most intrepid but arguably the most unsung of Allied Special Forces of the Second World War waged a guerrilla war against Japan for two years in the south-west Pacific. On some of their 81 operations Z Special Unit slipped into enemy harbors in canoes and silently mined ships before vanishing into the night; on others they parachuted into the dense Borneo jungle to fight with headhunters against the Japanese and on one occasion they landed on an Indonesian island and smuggled out the pro-Allied sultan from under Japanese noses. The Japanese weren't the only adversary that Z Special Unit encountered in the brutal terrain of the Pacific. In the mango swamps of Borneo and the dense jungle of Papua New Guinea they were faced with venomous snakes, man-eating crocodiles, and deadly diseases. But it was the enemy soldiers who proved the most ruthless foe, beheading those Z Special Unit commandos who fell into their hands. “Z was a different operation to anything else,” recalls veteran Jack Tredrea. “You were never told what you were going to do. You weren't allowed to talk about what you were training for in case any of us were caught. You could have been tortured and divulged information." Drawing on veteran interviews as well as operational reports and recently declassified SOE files, Gavin Mortimer explores the incredible history of this remarkable special forces unit and the band of commandoes that defied the odds.

March 1945. A handful of young Allied operatives are parachuted into the remote jungled heart of the Japanese-occupied island of Borneo, east of Singapore, there to recruit the island’s indigenous Dayak peoples to fight the Japanese. Yet most have barely encountered Asian or indigenous people before, speak next to no Borneo languages, and know little about Dayaks, other than that they have been – and may still be – headhunters. They fear that on arrival the Dayaks will kill them or hand them over to the Japanese. For their part, some Dayaks have never before seen a white face. So begins the story of Operation Semut, an Australian secret operation launched by the organisation codenamed Services Reconnaisance Department – popularly known as Z Special Unit – in the final months of WWII. Anthropologist Christine Helliwell has called on her years of first-hand knowledge of Borneo, interviewed more than one hundred Dayak people and all the remaining Semut operatives, and consulted thousands of military and other documents to piece together this astonishing story. Focusing on the operation's activities along two of Borneo’s great rivers – the Baram and Rejang – the book provides a detailed military history of Semut II’s and Semut III’s brutal guerrilla campaign against the Japanese, and reveals the decisive but long-overlooked Dayak role in the operation. But this is no ordinary history. Helliwell captures vividly the sounds, smells and tastes of the jungles into which the operatives are plunged, an environment so terrifying that many are unsure whether jungle or Japanese is the greater enemy. And she takes us into the lives and cavernous longhouses of the Dayaks on whom their survival depends. The result is a truly unique account of the encounter between two very different cultures amidst the savagery of the Pacific War.

Account of Australia's Z Special Unit's missions behind Japanese lines during the period 1942-45. It is a story about the courage, danger and initiative of the individuals and small groups who had little hope of help if their missions were unsuccessful.

Popularly known today as Z Special Unit, or by the wartime cover names of Inter-Allied Services Department (ISD) and Services Reconnaissance Department (SRD), Special Operations Australia (SOA) was the Special Operations component of the US-led Allied Intelligence Bureau in the Pacific Theatre during the Second World War. From the secret files of Z Special Unit, and the second in a set of five volumes, Volume 2 - Operations describes almost two hundred separate "Z" Operations. Through the examination of this volume, the strategic role of the Special Operations - Australia organisation becomes apparent. Students of history will easily identify the ebb and flow of the Allied campaigns in the Pacific Theatre, with many of the operations of SOA being precursors to larger Allied offensives. Several serious blunders by SRD headquarters are also identified, one of which in particular had the capacity to compromise one of the greatest secrets of the Second World War and could have cost thousands of Allied lives.
