Since May is the month of the Battle of Okehazama, I would like to share with you part of the Bukoyawa's version. You can find in David D. Neilson's Society at War (pp.84-85).
"Having changed direction we (the Kashiwaishu and the Sassa Clan), [left Narumi] and arrived at Zenshoji. By that time, we numbered only eighty or so men. Because Nakajima Fort had already been occupied by the Suruga army, there was nothing we could do [there].
Just then, someone raised a battle cry near Taishidake. It was dark on all sides and thunder shook both heaven and earth. We were in a state of shock and took petrified to move. Before long, a triumphant shout echoed from Hazama, but we could not tell if it was raised by friend or foe.
When Sassa Kuranosuke realized that he was late [for the battle], his face convulsed and told his party to dismount. Looking out over an area three cho (one cho=2.45 acres), we saw that the field curtains (maki) [of the Imagawa camp] were lying in the mud. Fallen men and horses created a terrible scene.
The Suruga army had disappeared like the ocean tide. Sassa Kuranosuke and the Kashiwaishu, we were all so close to Dengakuhazama, [but because we went to Narumi as directed by the Sassa Clan general who met us on the road and because we helped the Sassa Clan to fight at Narumi, we were unable to arrive at Hazama as ordered by Lord Nobunaga]. It was a great blunder. Kazusanosuke-sama (=Nobunaga), saw us, but ignored our presence. He departed for Kiyosu holding aloft a spear to which Imagawa Jibusho's severed head had been tied by the hair. Everyone was downhearted and that evening, we went back to Ryuzenji Fort."
The men of the fields went along with the Sassa to attack Narumi Castle. However, they were late to join Nobunaga and did not participate in the battle. Also it is quite possible that the Sassa attacked Narumi without Nobunaga's blessings. Senshu Suetada and Sassa Masatsugu were killed fighting at Narumi.
Tenka no tame!
