The purpose of this book is to recognise the major contribution of those many members of the Royal Australian Navy whose dedicated service in the Vietnam War was for so long ignored. These are the approximately 9,800 RAN personnel who, through dedication to the task over seven years, transported safely and on time about 15,600 Army and RAAF personnel, along with many tons of weapons, stores and equipment during the 25 operational voyages HMAS Sydney and her escorting destroyers made to and from Vietnam. Both authors are veterans of this major Vietnam logistic operation.
