Konoha Crush

The Invasion of Konoha was the planned invasion of Konohagakure by Otagakure and Sunagakure during the Chunin Exams. The Invasion was in truth Orochimaru's master plan for revenge on Konoha after the Third Hokage chose Minato Namikaze as the Fourth Hokage instead of him.

Plan
Sunagakure had a rocky relationship with Konoha, because it was the strongest village of the Four Nations. As time went on the Land of Wind's Daimyo started commissioning Konoha with requests he should have made to Sunagakure. On top of that, he began cutting back on Sunagakure's budget. The Fourth Kazekage realized that if he didn't act quickly, Sunagakure would be in danger of disappearing, so he joined forces with Otogakure in an attempt to destroy Konoha and force the lord to re-establish Sunagakure's military force if he wished for his village to survive.

The plan was to wait for ninja in the crowds to but a genjutsu on everybody so that Orochimaru could get close enough to Hokage where he would be able to trap himself and the Third in a dome created by his Sound Four. With the Hokage preoccupied, a giant Snake would be summoned and destroy part of the wall into the village, allowing the Sound and Sand ninja to break in. The secret weapon of the attack would be the Sands Jinchuriki, Gaara, the host of the One-Tailed Shukaku. Because Gaara could allow the Shukaku to take over, they could use the Shukaku to destroy Konoha.

Battle
The battle began as soon as the genjutsu was placed as Hatake Kakashi, Might Guy, Sakura Haruno were unaffected by the jutsu. Because Sasuke Uchiha had injured Gaara enough to make him slip into his Jinchuriki Form, the examiner told ordered Sasuke to follow Gaara and stop him, and that the exam was over. Kakashi told Sakura to wake up Naruto Uzumaki and Shikamaru Nara to stop Sasuke. Was the three went after Sasuke, Guy and Kakashi stayed at the arena to prevent the enemy shinobi to attack.
