Ogasawara Nagahide

Ogasawara Nagahide (小笠原長秀, September 18, 1366 - March 15, 1424) was a Japanese nobleman and military commander during the Muromachi period (1336 – 1573).

In this work, commissioned by the shōgun Ashikaga Yoshimitsu, he collated his family's practices of horsemanship, archery and etiquette, basing his knowledge on the teachings of his great-grandfather, Ogasawara Sadamune (1294 – 1350).

[2][3][4] Apart from his role in the compilation of the Sangi ittō ōsōji, Ogasawara was himself an expert at both bajutsu horsemanship and archery.

[5] He was, however, thwarted in the Battle of Ōtō, also called the Insurrection of Shinano, by a combined force of resident ji-samurai led by the Murakami family.

[7] The battle was first fought at Shinomiyakawara in present-day Nagano City, but after a loss there Nagahide fled with the remnants of his force of less than 800 horsemen to Shiozaki Castle.
