The Secret of the Battle (戦いの顛末, Tatakai no Tenmatsu) is episode 44 of the Naruto: Shippūden anime.
Sakura tries to heal Naruto, but her medical ninjutsu has little effect on his wounds. In the forest, Sai gives Orochimaru a letter from Danzō. Sai leaves with Orochimaru and Kabuto for their hideout, with Yamato's wood clone on their trail. After Naruto comes to his senses, the team travels to the area that has been the battlefield, where they find and pick up Sai's picture book. At the same time, Yamato reveals that Danzō seeks to destroy Konoha with Orochimaru's aid.
