The Fourth Shinobi World War (第四次忍界大戦, Daiyoji Ninkai Taisen, English TV: Fourth Great Ninja War) was a conflict between the Allied Shinobi Forces and Akatsuki. The battle began on the 8th of October and lasted until the 10th, with the complete victory of the Allied Shinobi Forces, the collapse of Akatsuki, and the sealing of the Ten-Tails.[1]

Preparations for War

Its beginning was declared by Tobi when the five Kage and the leader of the Land of Iron unanimously refused to surrender the Eight and Nine-Tails for his Eye of the Moon Plan. He then stated that he would use the seven tailed beasts already captured by the Akatsuki in combating the ninja world. After this the Fifth Kazekage, the Fifth Mizukage, the Fourth Raikage, the Third Tsuchikage, and General Mifune agreed to form a Shinobi Alliance, pooling all their resources against Tobi. Later the daimyō of the Five Great Shinobi Countries approved the coalition and the Fifth Hokage joined the alliance while Kabuto Yakushi formed an alliance with Tobi.

Both factions began by gathering their strength and collecting intelligence about the other side in preparation for the upcoming hostilities. Kisame gathered intelligence on Kumogakure's military strength and on Killer B while travelling with him everywhere hidden inside Samehada. Anko Mitarashi and her team tracks Kabuto Yakushi, which led them to Tobi's headquarters. Other Shinobi Alliance teams have fanned out to collect other information about Akatsuki and their hideouts.

At the start, Kabuto had formed an alliance with Tobi, demonstrating his use of the Summoning: Impure World Reincarnation technique and increasing the forces of Akatsuki with the reincarnation of deceased members of the organisation. Most of the Five Kage had also decided to hide the two remaining jinchūriki, Naruto and Killer B on an island in the Land of Lightning. Hiding Killer B and Naruto had the unintended result of allowing Naruto to learn to control the Nine-Tails chakra, much like the way Killer B has of the Eight-Tails (in the anime, however, Tsunade had intended for Naruto to train with B from the beginning). Having been successful in his training, Naruto has exhibited increased speed and strength when utilising the controlled chakra of the Nine-Tails but lacks the same finesse that Killer B had exhibited in utilising the Eight-Tails', crashing into the wall and crushing rocks whenever he uses the Nine-Tails chakra.

Despite being captured in the end and committing suicide to keep the information he held secret, Kisame was able to finish Akatsuki's preparations for the War by sending a summon shark with a scroll to his comrades, divulging the proximate location of the Turtle Island. With the battle between the two forces seeming to be on the horizon, Tobi dispatched Kabuto to retrieve the Nine-Tails and Eight-Tails with the reincarnated Deidara, but was stopped by Ōnoki, Akatsuchi and Kurotsuchi who were going to reinforce the forces on the Island Turtle. Kabuto escaped with Yamato, further adding to the intelligence sources that Akatsuki has on the Shinobi Alliance and also strengthening the White Zetsu Army clones with Yamato's powers.

Both the Allied Shinobi Forces and Akatsuki have amassed considerable forces for this war; 80,000 shinobi and samurai total make up the Alliance versus 100,000 Zetsu clones and reincarnated shinobi supplied by Kabuto making up Tobi's army. Sides

Allied Shinobi Forces

The Allied Shinobi Forces' "Great Battle Regiment".
The Allied Shinobi Forces created by the Five Great Nations and the Samurai of the Land of Iron consists of five main divisions, with Gaara of the Sand as the Regimental Commander. The First Division consists of mid-range fighters and is led by Darui. The Second Division is made up of close-range fighters and is led by Kitsuchi. The Third Division is under the command of Kakashi Hatake, and features both close- and mid-range fighters. The Fourth Division contains only long-range fighters under the control of Gaara. Shikamaru is Gaara's right hand man and proxy commander of the Fourth Division as well. Finally, the Fifth division was created for the purpose of special operations, and features ninja with unique skills. Mifune is the leader of these special operatives. There are also four special divisions formed for the war. The Logistical Support and Medical Division led by Shizune comprises of medical ninja, the Surprise Attack Division led by Kankurō, has the task to ambush the enemy forces. The third is the Sensor Division with Ao as captain, and finally the Intelligence Division headed by Inoichi Yamanaka is intended to gather information and relay it to Gaara for strategy's sake.

Akatsuki's forces.
Akatsuki is only composed of Tobi and Zetsu. Their primary military force is composed of 100,000 Zetsu clones created through a combination of the tailed beasts' chakra and Hashirama Senju's power. Tobi plans to use Sasuke Uchiha once he has recovered from his Mangekyō Sharingan transplant. Kabuto Yakushi has also formed an alliance with Akatsuki, reincarnating a large number of once-famous and powerful shinobi to supplement the White Zetsu Army, including several former members of Akatsuki.

Strategies

Allied Shinobi Forces

Initial Deployment

Fifth division deployment strategy.png
A diagram illustrating the Allied Shinobi Force's initial deployment.
Analysing their own and their enemy's location, the Allied Shinobi Forces have decided that Akatsuki will send a small fraction of their army by sea from the Mountains' Graveyard (Akatsuki's hideout) to Kumogakure, and that most of the army will travel by land. This would require the army to move through both the Land of Frost and the Land of Hot Water. An immediate evacuation notice was sent to both countries, and they will most likely evacuate to the south, in the Land of Fire. The First Division, which is the mid-range battle division, is stationed in the northern part of the Land of Lightning, in order to prevent the Akatsuki from using the small gulf to infiltrate the area from Mountains' Graveyard. The Second Division, or short-range battle division, is on the border of the Land of Lightning and the Land of Frost, sealing a northerly path into the Land of Lightning. The Third Division, or the short- to mid-range battle division, was advancing fast through the middle of the Land of Frost, but was called into the northern part of the Land of Hot Water to aid the Surprise Attack Division. The Fourth Division, the long-range battle division, is on the border of the Land of Lightning and the Land of Frost, sealing a southerly path into the Land of Lightning. Mifune's Fifth Division, the special battle division, is aligned in a large arc from the north part of the Land of Frost, through the middle of the border between the Land of Frost and the Land of Lightning, all the way to just south of the First Division, in order to aid any of the divisions that need immediate response, and to finish the seal on the Land of Frost and the Land of Lightning's border.

Secondary Deployment

Shikaku's Strategy.png
The initial Secondary deployment of the forces.
As the confrontation develops, resulting in both the First and Fourth Divisions opposing two separate yet equally significant contingents of the enemy's forces, Shikaku Nara devises a strategy to better reflect the conflict's current developments. Confronted with two distinct groups, the decision is made not to individualise the targets and instead concentrate entirely on those facing Darui's First Division, by connecting their forces with those stationed within the Easterly end of Mifune's Fifth Division. The majority of Kitsuchi's Second Division will move simultaneously to this, proceeding along the ocean and sandwiching the enemy force in a pincer-manoeuvre, while the remainder attends to the adversaries that they are already battling.

Shikaku Strategy.png
The secondary deployment with support.
Consequently, this will severely thin out the Second Division but as the Fifth Division fills in the gaps left behind by the Second Division, it will match that of the Fifth Division's formation, which then provides a solitary yet solid line of defence. As this occurs, Gaara's Fourth Division will make a slow retreat while moving into a sideways chevron formation, luring the enemy into following them. Eventually the top portion of this 'line' will break away and join the First Division, giving them yet further support. Once the first targeted group of enemies is defeated, the joint forces of the First and supporting Fourth Division will switch to the remaining opposition at Gaara's Fourth Division, approaching from behind and decimating them in a single decisive strike. However; this preliminary plan relies upon the swift mobilisation of the Second and Fifth Divisions, so as to best employ Kitsuchi's units experience in combating the current enemy, and the belief that the opposition will be unable to mount a full attack upon the retreating long-range battle division, due partially to the enemy's suspicion over why the Fourth Division would split and their inability to get in close.

Night-time Deployment

As darkness falls and the remainder of the troops reallocate their forces in favour of observation, the Alliance takes the opportunity to centralise the Logistical Support and Medical Division behind their defences to attend to all the wounded shinobi. The compound is guarded by two Akimichi clan members at its only entrance and the chakra of anyone entering the compound is verified and cross referenced with the Alliance's headquarters, to prevent the infiltration of hostile intruders.

However, in spite of these various precautions, the Alliance's considerable defences fail to thwart the intrusion of a significant quantity of disguised White Zetsu Army clones and the resultant fatalities caused by the opposition's subsequent movements. As chaos ensues with individuals unable to ascertain friend from foe due to the chakra mimicking properties of the aforementioned clones, Shikaku Nara is tasked with the creation of a solution to counter this sudden perilous development. Despite much thought, he concludes that only Naruto's recently awakened capability to discern a person's "evil" intent, presents a viable resolution and due to his Shadow Clone Technique, many of the issues occurring within the dispersed divisions are solved simultaneously. This decision prompts the mobilisation of both jinchūriki in preparation for the following day.

Akatsuki

Day One Deployment

Much less was initially known about the Akatsuki strategy, but it was made evident that their primary objective remained the acquisition of the surviving jinchūriki. From the small amount of information that had been divulged; Kabuto would maintain direct manipulation of the movements of the reincarnated individuals until they had reached their appointed destinations, with the intention of eradicating their personalities when the actual conflict began to turn them into mindless implements of death, while still manipulating any emotional response they could potentially illicit to full advantage, in the hopes of inflicting further damage. During the course of this approach, a small Surprise Attack and Diversion Platoon (comprised of Sasori, Deidara, Chūkichi and Shin) would attack from the air, utilising bombs and traps to disperse the enemy. However, realising that the movement of their entire army in such a large and apparent fashion would be far too conspicuous, the decision was instead undertaken to dislocate the 100,000 White Zetsu Army clones beneath the ground, in order to thoroughly conceal the approach of the main contingent of their forces. Though a large amount of these clones were eventually unearthed, thousands more were able to proceed unobstructed underground to their respective battlegrounds, due in part to the diversionary tactics made possible by the addition of Kabuto's reincarnated shinobi.

Concurrent to the developing conflict, Black Zetsu would utilise the resulting turmoil in order to infiltrate the daimyō's safe house as per Tobi's orders, with the sole intention of using these valued captives as bargaining chips to draw out the jinchūriki. However, with the jinchūriki's decision to expose themselves and take direct action before this assignments completion, it was deemed unnecessary and so Black Zetsu's role was altered to instead engage with the daimyō's guards, ensuring their continued separation from the remainder of the Allied Shinobi Forces.

Night-time Deployment

As the confrontation progresses and night falls upon the first day, Tobi's true intentions and the reasons behind his confidence in his original strategy, which didn't account for Kabuto's inclusion or contributions, is revealed. The two opposing sides would effectively be forced into a staring contest as the Allied Shinobi Forces focus on tightening defences and tending to the wounded or resting. Tobi, aware that this would make the Allied Shinobi completely reliant upon their sensor shinobi in order to remain vigilant, then begins taking this advantage of this by utilising the Zetsu clones' Substitute Technique in conjunction with the chakra obtained from members of the Allied Shinobi Forces during the previous battles. By covertly placing these transformed Zetsu among the injured and scattered troops of the Allied Shinobi, they could then proceed to assassinate any isolated individuals while remaining undetected. This results in causing chaos and disagreement within the ranks of the Allied Shinobi who begin to suspect one another of committing these deeds without any definitive proof, but while also minimising the causalities suffered by the Akatsuki forces in the process. In addition, the attack of the transformed Zetsu also aimed to force the shinobi alliance to counter these insurgents, placing Naruto in the battlefield whose ability to recognise "evil" intent Tobi has learned from the intel gathered by Kisame.

Unbeknownst to the opposition, Tobi had also begun developing further contingencies in preparation for the second day of the conflict, creating his own Six Paths of Pain by utilising the former jinchūriki and customising them with both a Rinnegan and a Sharingan.

Following the success of their first mission, part of the Surprise Attack Division is sent to ambush another Akatsuki cell. They encounter a group consisting of Zabuza Momochi, Haku, Pakura, Gari and, though outnumbered, attack. When the attack fails, the Third Division is called in to assist. Akatsuki's forces - reinforced with reincarnated members of the Seven Ninja Swordsmen of the Mist (and Chen in the anime) - cause heavy casualties amongst the Third Division. Zabuza and Haku are successfully sealed early on, but sealing of the others proves more challenging. By the second day of the war three reincarnated shinobi remain, now bolstered by White Zetsu. The assistance of one of Naruto Uzumaki's shadow clones enables the Third Division to deal with the remaining Akatsuki forces.

When the war begins, the Second Division is deployed to the border of the Land of Frost and the Land of Lightning. Approximately 20,000 White Zetsu are detected moving into the Land of Lightning underground, prompting Kitsuchi and Kurotsuchi to use Earth Release: Opening Earth Rising Excavation to unearth them. In an opening salvo the Second Division is able to destroy scores of White Zetsu, but it quickly descends into one of attrition, tiring much of the Second Division and allowing many White Zetsu to escape. Most of the Second Division is sent in pursuit of these Zetsu by assisting the First Division, leaving their remaining forces to face a new threat: White Zetsu that have infiltrated the Alliance. Members of the Second Division are slowly eliminated by the Zetsu and left uncertain about who to trust until the second day when the arrival of one of Naruto Uzumaki's shadow clones allows them to root out all of the Zetsu.

First Battle on the Land of Lightning's Coast

Location: North-western coast of the Land of Lightning
Combatants
Akatsuki: Thousands of the White Zetsu Army, Asuma Sarutobi, Hizashi Hyūga, Dan Katō, Kakuzu, Kinkaku, Ginkaku

When the war begins, the First Division is stationed along the north-western coast of the Land of Lightning. They are soon confronted by the reincarnated shinobi and White Zetsu that escaped the Second Division's defence along the country's perimeter. The two sides engage each other, with Division Commander Darui facing off with the Gold and Silver Brothers. Darui initially struggles with the brothers and their Treasured Tools of the Sage of Six Paths, but eventually is able to turn the tools against the brothers to capture Ginkaku in their own Benihisago. This enrages Kinkaku to the point that he enters a version 2 form, which he uses to tear through the First Division. After reinforcements from the Second, Fourth, and Fifth arrive and the Alliance HQ sends the Kohaku no Jōhei to the battlefield, Kinaku is captured.

With the Gold and Silver Brothers dealt with, the Allies turn their attention to the remaining reincarnated ninja: Asuma Sarutobi is defeated by his former students; Kakuzu and Hizashi Hyūga are sealed with the help of Chōji Akimichi; Dan Katō is trapped within a Four Violet Flames Formation. The remaining White Zetsu are seemingly defeated, leaving the Allies victorious.

Almost immediately after the First Division and its backup defeats the last of Akatsuki's forces, Tobi appears on the battlefield and summons the Demonic Statue of the Outer Path. Despite the efforts of Kitsuchi, Chōza, and Chōji, the Statue decimates the Allied forces. While taking shelter from the Statue's attacks, members of the First Division begin to realise the attack is just a distraction while Tobi acquires the captured Gold and Silver Brothers. They aren't able to stop him in time and he escapes with the Benihisago and Kohaku no Jōhei. His mission accomplished, Tobi de-summons the statue.

The Battle for the Daimyō's Protection

Akatsuki: Black Zetsu
Allied Shinobi Forces: Daimyō Protection Squad, Naruto Uzumaki's shadow clone
Duration
Manga: Chapter #536 to #562
Anime: Naruto: Shippūden #276 to #322
Outcome: Black Zetsu's upper half is incapacitated. Lower half escapes. Allied Shinobi Forces victory.
In order to force the Allies' cooperation, Black Zetsu is sent to capture the daimyō of the Five Great Shinobi Countries. He is found and stopped by the Daimyō Protection Squad almost immediately after he arrives at the secret compound. Before he begins fighting he senses Naruto Uzumaki's appearance on the battlefield and informs Tobi of this development. The daimyō's capture ceases to matter, but Black Zetsu is instructed to keep the Daimyō Protection Squad busy. One of Naruto's shadow clones arrives on the second day to help capture Black Zetsu.

At the end of the first day of the battle, both the Alliance and Akatsuki received massive casualties, having effectively halved both their battle forces. The 80,000 strong Allied Shinobi Forces were brought down to 40,000 and the 100,000 strong White Zetsu Army was brought down to 50,000, on top of the several already sealed reincarnated shinobi.

During the day of fighting, members of the White Zetsu Army infiltrated the Alliance's ranks. Once night falls, the disguised Zetsu begin methodically eliminating key Allied personnel all across the battlefield. The Alliance is thrown into disarray until Sakura Haruno is able to determine what is happening. Despite this, there are no effective countermeasures against the Zetsu and vigilance is unable to prevent additional deaths. Suspicion reigns over the Allies.

Early in the night, Naruto and Killer B escape their confinement in the Land of Lightning. Although the Fourth Raikage and Fifth Hokage are sent to intercept them and place them under guard again, Naruto, B and later Tsunade are able to convince the Raikage to allow him and B to fight.

Naruto and B's contributions immediately prove invaluable. They encounter a platoon of Allied shinobi heading towards HQ, which Naruto recognises as disguised Zetsu. Naruto and B defeat them all and Naruto sends his shadow clones to various battlefields to lend whatever assistance they can. As Naruto and B continue outbound from the Land of Lightning, they are able to save Musai and Nonota from a reincarnated Toroi.

First Southern Battle in the Land of Lightning

Location: Land of Lightning
Combatants
Akatsuki: Mū, Second Mizukage, Third Raikage, Fourth Kazekage, Giant Clam
Allied Shinobi Forces: Part of the Fourth Division with its Commander Gaara, Ōnoki, Naruto Uzumaki's shadow clone
Duration
Manga: Chapter #546 to #558
Anime: Naruto: Shippūden #296 to #302
Outcome: Dozens of Allied Forces shinobi are killed. The Third Raikage, Second Mizukage, Fourth Kazekage, and half of Mū are sealed. Allied Shinobi Forces victory.
The Fourth Division encounters the reincarnated Mū on the first day of hostilities. Akatsuki responds by sending the Second Mizukage, the Third Raikage, and the Fourth Kazekage to reinforce Mū. The Alliance likewise sends Ōnoki to assist the Fourth Division. Despite this, the Fourth Division avoids conflict until the second day when other Divisions - their own battles won - can be called in to help.

Gaara launches the first attack - which in turn is countered by the Fourth Kazekage's gold dust - Ōnoki engages Mū, and elements of the First Division attack the Raikage and Mizukage from the rear. The Fourth Kazekage is captured and sealed while protecting the Raikage and Mizukage, but the remaining Kage are more elusive: the Raikage is largely impervious to damage, the Mizukage and his summoned clam cannot be located in their mirage, and Ōnoki is unable to overpower Mū.

When Naruto's shadow clone arrives it takes Mū by surprised and, in the ensuing confusion, Mū is sealed before he can respond. Naruto next focuses on the Third Raikage, whose defences are impenetrable and whose attacks are unstoppable. When his and the Alliance's combined efforts can do nothing against the Raikage, Naruto manoeuvres the Raikage against himself, using his own attacks to break his own defences and creating an opening to seal him. Meanwhile, Gaara and Ōnoki face-off with the Mizukage. They're able to destroy the Mizukage's clam, but struggle with his Steaming Danger Tyranny. Gaara is ultimately able to sneak some of the Fourth Kazekage's remaining gold dust into the Mizukage's technique, neutralising it and allowing the Mizukage to be sealed.

To that end, he sends the reincarnated Nagato and Itachi Uchiha after them. While Nagato attacks them with different summons, Itachi activates the Kotoamatsukami he planted on Naruto before his death, releasing him from Kabuto's control and allowing him to assist with defeating Nagato. Though his body was frail, Nagato is able to regain his mobility by absorbing B's version 2 chakra. Although this revvitalised Nagato is nearly able to remove Naruto's soul, he is overpowered by the three and sealed by Itachi's Susanoo.

Second Southern Battle in the Land of Lightning

Location: Land of Lightning
Combatants
Akatsuki: Madara Uchiha, Mū's other half
Allied Shinobi Forces: Fourth Division, the five Kage, the Hokage Guard Platoon, Naruto Uzumaki's shadow clone
Duration
Manga: Chapter #559 to #600
Anime: Naruto: Shippūden #321 to #343
Outcome: Heavy Allied Shinobi casualties. All Kage critically wounded. Mū released from the Impure World Reincarnation. Madara severed contract with technique and rendezvous with Tobi. Akatsuki victory.
When he was attacked by Naruto's shadow clone earlier, Mū's body instinctively split in two, of which only one was sealed. The second half cannot release the first half, so Kabuto uses the only option he has left: he uses Mū as a medium to summon a reincarnated Madara Uchiha. Kabuto encourages Madara to show what made him so legendary, which Madara obliges by attacking the nearby Fourth Division. Gaara, Ōnoki, Naruto's shadow clone, and the rest of the Allies present are already outmatched by Madara, which is only made worse when Madara drops two meteorites upon them, wiping out most of the Fourth Division. Madara attacks the survivors with Wood Release Secret Technique: Nativity of a World of Trees, which Naruto does his best to defend against.
