Upon receiving the order, Mitsuhide returned to Sakamoto Castle and moved to his base in Tamba province

 with several prominent poets, where he made clear his intentions to rebel.

Mitsuhide saw an opportunity to act, when not only was Nobunaga resting in Honnō-ji and unprepared for an attack, but all the other major daimyo and the bulk of Nobunaga's army were occupied in other parts of the country.

Mitsuhide led his army toward Kyoto, claiming that Nobunaga wanted to show a procession. It was not the first time that Nobunaga had demonstrated his modernized and well-equipped troops in Kyoto, so this excuse was not doubted. Finally, when getting near to Honnō-ji, Mitsuhide announced, "The enemy awaits at Honnō-ji!" (Teki wa Honnōji ni ari! 敵は本能寺にあり)

Before dawn, the Akechi army had Honnō-ji surrounded in a coup

. Nobunaga and his servants and bodyguards resisted, but they realized it was futile against the overwhelming numbers of Akechi troops. Nobunaga committed suicide, reportedly his last words were, "Ran, don't let them come in..." (Referring to his young page, Mori Ranmaru who set the temple on fire as Nobunaga requested so that no one would be able to get his head). Ranmaru then followed suit. His loyalty and devotion makes him a revered figure in history. Nobunaga's remains were not found, a fact often speculated about by writers and historians.

After capturing Honnō-ji, Mitsuhide attacked Nobutada

 to boost his position and force the court to recognize him as well.

Reasons for the coup

Akechi Mitsuhide's reasons for the coup are a mystery that has been a source of controversy and speculation. Although there have been several theories, the most common ones maintain that Mitsuhide bore a personal grudge, acted out of fear, had the ambition to take over Japan, was simply acting to protect the imperial court whose authority was not respected by Nobunaga, or was trying to remove the iconoclastic revolutionary. Many think it was a combination of at least some of the above assumed reasons.

, Akechi was the official in charge of catering to the needs of Ieyasu's group. Subsequently, he was removed from this post for some reason. One story spoke of Nobunaga yelling at him in front of the guests for serving rotten fish.

Another story said that when Nobunaga gave Akechi the order to assist Hashiba Hideyoshi, it was somehow hinted that Akechi would lose his current territories and would have to fight for land which was not even under Oda control yet. As Nobunaga had sent two senior retainers under him, Sakuma Nobumori

, Akechi Mitsuhide supposedly sent his mother as a hostage into the hostile Yagami Castle to convince the Hatano clan to surrender. Nobunaga, however, had the Hatano brothers executed, an act that caused former Hatano retainers to kill Akechi's mother. Akechi Mitsuhide felt humiliated and depressed by this and eventually decided to kill his master. This story, however, only began to circulate during the Edo period
