A Pocket Guide to Netherlands East Indies was originally a 5.25"x4.24" pocket-size booklet released in 1943 for American GIs in World War II on their way to Indo-European countries, including Sumatra, Java, and Borneo, which were near territories occupied and controlled by the Japanese. The pamphlet outlines the role of the soldier, as well as descriptions of the different countries and peoples, their habits and cultures, and the native vegetation and wildlife. The booklet includes a map of the 3,000 countries making up the East Indies, guides to currency, time, measurements, and language, and a list of dos and don'ts when interacting with the general population. The War and Navy Departments, Washington D.C., publish pamphlets, reports, manuals, and instructions ranging on topics from countries and regions of the world, machine and weapon operation, roles of persons and positions, vehicle operation and safety, and other topics pertinent in wartime and for the military.

Between 1966 and 1980, the War History Office of the National Defense College of Japan (now the Center for Military History of the National Institute for Defense Studies) published the 102-volume "Senshi Sosho" (War History Series). These volumes give a detailed account of the operations of the Imperial Japanese Army and the Imperial Japanese Navy during the Second World War. Volume 3 of the series, "The Invasion of the Dutch East Indies", describes in depth the campaign to gain control over the Indonesian archipelago - at that time the largest transoceanic landing operation in the military history of the world. The present book is the first complete and unabridged translation of a volume from the comprehensive "Senshi Sosho" series. It enables military historians and the general public to see and study for the first time how the operation that put an end to Dutch colonial rule in Indonesia was planned and executed.
