Contrary to what many Australians believe, during 1942 Japanese submarines were active in Australian waters and Japanese spy planes made surveillance flights over our major cities. With enemy submarines patrolling off the Western Australian coast, Fremantle became an important international submarine base, the largest in the Southern Hemisphere. During the war Fremantle played host to over 170 Allied submarines, with submarines of the United States, British and Dutch navies making a total of 416 war patrols out of the port between March 1942 and August 1945. The secrecy surrounding the operation of the Fremantle submarine base meant that its existence was little known at the time and, until now, has been largely forgotten by history.

From unpromising beginnings in March 1942, the Allied submarine base at Fremantle on the west coast of Australia became a vital part of the Allied offensive against Japan. Pushed back from the Philippines and the Netherlands’ East Indies, American submariners, accompanied by a small group of Dutch forces, retreated to Fremantle as a last resort. The location was chosen for its good harbor and the fact that it was outside the range of land-based Japanese aircraft. Unfortunately the base was also far from their patrol areas and supply lines, and it was difficult to reinforce should the enemy attack. Thanks largely to a welcoming civilian population, morale quickly improved. The hospitality and sense of belonging fostered by Western Australians became legendary among Allied submariners and remains central to their wartime memories. Perhaps as a result of such a positive experience, the Allied forces became much more successful in combat. Intertwining social and military history, Fremantle’s Submarines relates how courage, cooperation, and community made Fremantle arguably the most successful military outpost of World War II from the standpoint of troop morale.

The submarine emerged as a serious weapons system during the First World War (1914 - 1918). During that conflict Germany with its unrestricted submarine warfare campaign of 1917 nearly drove Great Britain to the negotiating table. Its U-boats sank 6,196 ships of 13,438,632 gross register tons. Despite post-war attempts to ban the submarine from warfare, it survived. Both Italy and Germany used submarines, covertly, during the Spanish Civil War (1936 - 1939). This book, Part Two of a series, discusses the use of submarines during World War Two (1939 - 1945) and their effectiveness. It focuses principally on two strategic submarine campaigns. The first is about German U-boats against British and neutral commerce. That campaign finally failed during the Battle of The Atlantic in 1943. The second deals with American submarines against Japanese shipping from Southeast Asia to the home islands, a campaign that successfully isolated Japan from its sources of raw materials and foodstuffs during 1944 and effectively defeated Japan.

Only seven U.S. submariners earned the Medal of Honor in World War II. Sam Dealey, the USS Harder's commander, was one of them. His honor was awarded posthumously after the entire crew was lost off Bataan during a depth-charge attack in August 1944 by a Japanese convoy. The Harder's fighting spirit is legendary, and its record of sinking a total of eighteen enemy ships (with a tonnage in excess of 55,000) made Dealey one of the top five submarine skippers in the war. During a single patrol his crew sank five enemy destroyers in five short-range torpedo attacks —an unprecedented feat. In addition, the Harder played important roles in rescue missions, extracting secret operatives deep in enemy territory and saving downed pilots. Drawing on previously untapped sources, Michael Sturma, an Australian teaching at Murdoch University, details several daring missions, one that involved the heroic Australian commando Bill Jinkins, and puts the Harder's action in the context of the overall Pacific campaign. In do so, the author adds not only significant information to the Harder's story but also provides a fresh perspective on the submarine war.

This volume concerns the history of the Australian port of Fremantle, located on the edge of Western Australia and the Indian Ocean, throughout the hundred years of frequent changes to its structure and function between 1897 and 1997. Tull’s aim is to use Fremantle as a prime example of the complex network of a Port, as a community and a place of vast and varied maritime business endeavours. He seeks to erase the perception of ports as ‘passive links in the international transport chain’ in order to draw ports to the attention and further research of maritime historians. The chapters are arranged thematically rather than chronologically, and includes statistical appendices, a bibliography, and an index, for ease of navigation.

Submariners are a tight knit group of men bound together by training and experience, and with a language all their own. That language is perhaps a little vulgar, but never intentionally demeaning, and a little irreverent but still worldly. This work is an attempt to preserve and explain some of these curious guys who so proudly wear a shiny metal pin that looks like a strange pair of fish on their left breast. This process of accumulating this new language begins in Boot Camp, and is added to with every change of duty station the sailor undergoes. It is heard aboard the boats and, unknowingly, by family members who can't understand terms like head, deck, and overhead, and who think SOS is a distress signal.

This book reveals the historical context and the evolution of the technically complex Allied Signals Intelligence (Sigint) activity against Japan from 1920 to 1945. It traces the all-important genesis and development of the cryptanalytic techniques used to break the main Japanese Navy code (JN-25) and the Japanese Army’s Water Transport Code during WWII. This is the first book to describe, explain and analyze the code breaking techniques developed and used to provide this intelligence, thus closing the sole remaining gap in the published accounts of the Pacific War. The authors also explore the organization of cryptographic teams and issues of security, censorship, and leaks. Correcting gaps in previous research, this book illustrates how Sigint remained crucial to Allied planning throughout the war. It helped direct the advance to the Philippines from New Guinea, the sea battles and the submarine onslaught on merchant shipping. Written by well-known authorities on the history of cryptography and mathematics, Code Breaking in the Pacific is designed for cryptologists, mathematicians and researchers working in communications security. Advanced-level students interested in cryptology, the history of the Pacific War, mathematics or the history of computing will also find this book a valuable resource.
