Entering service during the Sino-Japanese War, the Nakajima B5N (code-named ‘Kate’) excelled and went on to achieve surprising and dramatic successes in the Japanese attack on Pearl Harbor.It also contributed to the sinking of the US aircraft carriers USS Lexington at the Battle of the Coral Sea, USS Yorktown at the Battle of Midway, and USS Hornet at the Battle of the Santa Cruz Islands. Its replacement, the Nakajima B6N ‘Jill’, while a marked improvement over its illustrious predecessor, was never able to achieve its full potential in combat due to advances in Allied aircraft, finding itself relegated to the dreaded Kamikaze strikes in the latter part of the war.Using previously unpublished photographs as well as colour illustrations, this book will cover the history of the ‘Kate’ and ‘Jill’ torpedo/attack bombers, including their design and development, as well as the combat highs and lows of the Imperial Japanese Navy’s premier torpedo-bombers.

A fascinating insight into how the Allies learned about the capabilities and limitations of the Imperial Japanese Naval Air Force and Japanese Army Air Force through flight testing and evaluation of enemy equipment.In the Pacific War’s early years, Japanese air power was dominant. The only way for the Allies to defeat their enemy was to know it. This made the task of maintaining productive intelligence gathering efforts on Japan imperative.Establishing Technical Air Intelligence Units in the Pacific Theatre and the Technical Air Intelligence Center in Washington DC, the Allies were able to begin to reveal the secrets of Japanese air power through extensive flight testing and evaluation of captured enemy aircraft and equipment. These provided an illuminating perspective on Japanese aircraft and aerial weapon design philosophy and manufacturing practice.Fully illustrated throughout with a wealth of previously unpublished photographs, Mark Chambers explores Allied efforts to evaluate the strengths and weaknesses of Japanese air power during the war years, and how this intelligence helped them achieve victory in the Pacific.

In 1938, the Yokosuka Naval Air Technical Arsenal, acting under the requirements issued by the Kaigun Koku Hombu for a Navy Experimental 13-Shi Carrier Borne specification for a dive-bomber to replace the venerable ‘Val’ aboard carriers.The resulting D4Y Suisei (‘Comet’), codenamed ‘Judy’ by the Allies, was initially powered by a licence-built German Daimler-Benz DB 601 inline engine as used in the Bf 109E. Despite making an inauspicious combat debut during the Battle of Midway in June 1942, the ‘Judy’ eventually proved to be an important asset for the IJNAF during battles in the latter years of the Pacific War. Its great successes resulted in the sinking of the escort carrier USS Princeton in an early kamikaze attack of the Philippines and the near sinking of the fleet carrier USS Franklin in a dive-bombing attack off Japan. While the Judy had an impressive top-speed, like its predecessor, and many other Japanese military aircraft, it possessed design shortcomings including inadequate armour protection for its aircrew and no self-sealing fuel tanks. As a result, when pitted against new, advanced US Navy fighters suffered horrendous losses. During the final months of World War 2 it became apparent that there would be no Japanese victory. Acting out of desperation, the IJNAF employed the ‘Judy’ in the dreaded kamikaze role, in which it excelled due to its high-speed characteristics. Most notably, the D4Y mounted one of the last combat actions of World War 2 when a flight of 11 Judies, personally led by the instigator of the suicide attacks, Vice Admiral Matome Ugaki, took off on a ‘search mission’ on August 15, 1945. This volume chronicles the action-packed wartime exploits of Japan’s finest dive-bomber of World War 2.

While the histories of gold, silver, and copper mining and smelting are well studied, lead has not received much scholarly attention despite a long history of both Native American and European desire for the ore. Over time, native peoples made lead ornaments in molds; French and American settlers used lead to form musket balls; red lead became an important production element for flint and crystal production; and white lead was used in making paint until the mid-twentieth century.Gray Gold aims to broaden understandings of early colonial and Native American history by turning attention to the ways that mining—and its scientific, technological, economic, cultural, and environmental features—shaped intercultural interactions and developments in the New World. Backed by remarkable original sources such as firsthand mining accounts, letters, and surveys, Mark Chambers’s study demonstrates how early mining techniques affected the culture clash between Native Americans and Europeans all the while tracking the impact increased mining had on the environment of what would become the states of Illinois and Missouri. Chambers traces the evolution of lead mining and smelting technology through pre-contact America, to the amalgamation of aboriginal processes with French colonial development, through Spain’s short occupation to the Louisiana Purchase and ultimately the technology transfer from Europe to an efficient and year-round standard of practice after American assumption. Additionally, while slavery in early American industry has been touched on in iron manufacturing and coal mining scholarship, the lead mining context sheds new light on the history of that grievous institution.Gray Gold adds significantly to the understanding of lead mining and the economic and industrial history of the United States. Chambers makes important contributions to the fields of United States history, Native American and frontier history, mining and environmental history, and the history of science and technology.

Mycobacteria are bacterial pathogens which cause diseases in humans and non-human animals. This monograph primarily covers the most important and widely researched groups of mycobacteria: members of the Mycobacterium tuberculosis complex (MTC) and Mycobacterium leprae, across a wide range of host species. M. tuberculosis and M. bovis are particularly relevant with the increasing drug resistance and co-infection with HIV associated with M. tuberculosis and the possible cross-infection of badgers and cattle associated with M. bovis. This book provides a reference for researchers working in different fields, creating a work which draws together information on different pathogens, and by considering the diseases in a zoonotic context, provides a One Health approach to these important groups of diseases.

This book is contemporary, topical and global in its approach, and provides an essential, comprehensive treatise on bovine tuberculosis and the bacterium that causes it, Mycobacterium bovis. Bovine tuberculosis remains a major cause of economic loss in cattle industries worldwide, exacerbated in some countries by the presence of a substantial wildlife reservoir. It is a major zoonosis, causing human infection through consumption of unpasteurised milk or by close contact with infected animals. Following a systematic approach, expert international authors cover epidemiology and the global situation; microbial virulence and pathogenesis; host responses to the pathogen; and diagnosis and control of the disease. Aimed at researchers and practising veterinarians, this book is essential for those needing comprehensive information on the pathogen and disease, and offers a summary of key information learned from human tuberculosis research. It will be useful to those studying the infection and for those responsible for controlling the disease.
