In June 1560, Nobunaga's scouts reported that Yoshimoto was resting at the narrow gorge of Dengaku-hazama, ideal for a surprise attack, and that the Imagawa army was celebrating their victories of Washizu and Marune fortress. While Yoshimoto viewed victory ahead, Nobunaga’s forces soon arrived at the Zensho-ji, a fortified temple overlooking the Imagawa forces camp site. Nobunaga ordered his men to set up an array of flags and dummy troops made of straw and spare helmets around the Zensho-ji, giving the impression of a large host, while the real Oda army hurried round in a rapid march to get behind Yoshimoto's camp. The heat gave way to a terrific thunderstorm, and as the Imagawa samurai sheltered from the rain, Nobunaga deployed his troops at Kamagatani. When the storm ceased, they charged down upon the enemy. At first, Yoshimoto thought a brawl had broken out among his men, but then he realized that it was an attack when two of Nobunaga's samurais, Mōri Shinsuke and Hattori Koheita, charged up at him. One aimed a spear at him, which Yoshimoto deflected with his sword, but the second swung his blade and decapitated him. With his victory in this battle, Oda Nobunaga gained greatly in prestige, and many samurai and warlords pledged fealty to him.
