Samurai [PDF ebook] 
A Military History

First published in 1977, The Samurai has long since become a standard work of reference. It continues to be the most authoritative work on samurai life and warfare published outside Japan. Set against the background of Japan’s social and political history, the book records the rise and rise of Japan’s extraordinary warrior class from earliest times to the culmination of their culture, prowess and skills as manifested in the last great battle they were ever to fight – that of Osaka Castle in 1615.
