In this episode we bring to life the history of Japanese castles using gameplay from Assassin's Creed Shadows. We begin with a broad overview of the history of fortifications in ancient Japan. This began early on with the fortification of temples and noble homes. Yet it would primarily be in the late Heian period of the 11th century that a particular style of construction emerged known as the Yamashiro (or hill castle). The basic idea was to create terraces atop hills and mountains and then reinforce them with interconnected baileys. From then on, these fortifications would get increasingly large, covering entire mountains in intricate killing fields. Eventually the greatest of these would be so massive that they had to be moved down into the plains.

In this history documentary we seek to bring to life an army of the Sengoku Jidai. Such a task is quite the undertaking given the poorly documented and fast-evolving nature of the eras military forces. Yet we can nonetheless model a typical Samurai army which captures most of the key themes of the period.
We begin with context on the history of Japan from the early Heian period though the Kamakura, Muromachi, and eventual Sengoku eras. Next we establish the general structure of a Daimyo Kashindan and how this network of vassals mobilized its forces. This includes mobilization records of the Koku based system which give us a sense of each vassals obligations. We then inspect each type of soldier which went to war. This includes peasant non combatants, ashigaru troops, and samurai warriors.
Finally, with all these pieces in place we see how the mustered forces were organized into an army. This begins at the smallest level of the Go (squad) and rises up to the tactical unit of the Sonae (battallion). Multiple Sonae would in turn be configured into the major elements of an army in the field. We conclude with a final positioning of such forces as they may have existed in an actual Samurai battle of the Sengoku Jidai.
