Assault…!! (強襲…!!, Kyōshū…!!) is chapter 114 of the original Naruto manga.
Not only did Sasuke's Chidori pierce the Shield of Sand, but it also managed to damage Gaara. This being the first time he has ever been injured, Gaara is distraught and ends the transformation he was working towards midway. Naruto, despite having worried for Sasuke's safety moments earlier, is suddenly envious. Since Gaara's injury has ruined their original plans, the Suna and Oto try a different approach. A genjutsu is placed over the stadium, putting most of the audience to sleep. The Fourth Kazekage attacks the Third Hokage, beginning the invasion of Konoha.
