Narces, the master general who succeeded Belisarius of the Byzantine Empire.

 Emperor Justinian, who did not trust Velisarius, sends only a small reinforcement to him despite Velisarius's request. In the end, because of Emperor Justinian's attitude, Belly Sarius could not even try to recapture Italy and had no choice but to waste years from this port to that port between the fortresses and perform a "hit and run" type of discharge. Eventually, Belisarius gave up his mission and returned to Constantino in 548 with the permission of the emperor, saying it was useless to expect enough troops from Emperor Justinian, who did not trust him. Four years later, Justinian, who regretted the decision to give up Italy, decided on a new expedition. Justinian, who feared that Velisarius would build a new country against East Rome, eventually gave Narces command instead of Velisarius because he was unhappy with taking command. Narcissus had long studied war thoroughly and proved his real capabilities even when Velisarius made great contributions throughout Italy. Narcissus made the most of the opportunities he was given. First, instead of accepting the emperor's offer, he was provided with a well-armed unit with excellent combat power. He led this unit around the coast of Adria and moved north. At this time, it was judged that Gaut-gun would surely attack through the sea because it was difficult to move along the rough coastal road through numerous river estuaries, and as a result, it helped Narces invade. However, Narcissus was able to advance faster than expected by the enemy and arrive at Ravena without much resistance by using a large number of boats as land mobile units, transitions, and secondary bridges. Narces made a detour to the fortresses that were blocking the attack route without delay, which was aimed at inducing battle before Tortilla's troops were fully gathered. Tortiral had secured a major passage for the Apenino Mountains, but Narces moved along the detour and attacked Tortilla in Tagina. Velisarius should have always fought with fewer troops than the enemy throughout the previous country, but Narces already had a dominant force over the Gottes. Nevertheless, Narcissus, who took the advantage as much as possible through a strategic offensive, used tactical defense against Totilla. With the instinctive "aggressiveness" in mind, he was trying to induce their preemptive attack and trap them. This was a tactic that had a profound impact on the British army, which fought against French cavalry at the Battle of Cracy more than 800 years later, based on the fact that the Gotts were looking down on Byzantine infantry, which were vulnerable to cavalry attacks. He first let the cavalry get off the horse and then placed them in the center on a large scale to use the spear they were carrying for the battle of infantry, while making it look like a spearhead to the enemy. On both sides of this large scale, infantry archers were sufficiently deployed forward in the shape of a crescent moon so that they could respond at any time when there was an attack on the center, and most cavalry were placed at a short distance behind them. On the ridge sufficiently spaced apart from the front of the left wing, elite cavalry units were deployed so that if the Gotts attacked deeply, they could launch a surprise attack on their rear. As such, the trap carefully prepared was successful as it was. The Gott cavalry expected the infantry located in the center of the enemy's large scale to be weak and launched an attack against it. They suffered great losses from intensive shooting from the side during their advance, stuck in front of the solid defense of the Chang cavalry from the horse, and the loss was further increased by archers approaching from their side. Meanwhile, the Gautt infantry were hesitant to launch a support attack for fear of being attacked in the rear by cavalry archers Narces placed on the ridge on the side. The Gaut cavalry, which had continued its reckless attack, began to retreat, when Narces launched a decisive counterattack with the cavalry he had so far. The loss suffered by the Gauts here was truly great, so Narces had rarely encountered strong resistance during his subsequent restoration of Italy. With the timely completion of the Goat conquest, Narces was relatively free to cope with the newly attacked Frank with Goat's desperate plea. In this attack, Frank pushed deeper than before and reached Campania. In the meantime, Narcissus appears to have aimed for Frank's "Self-Defense" by breaking the battle until the enemy's combat power declined due to long-distance marches and dysentery. However, when Frank launched the attack at Casillinum in 553, he still had 80,000 troops. At this time, Narces devised a trap that fits perfectly with his typical tactics. The enemy army, consisting of infantry, attacked with weight and impact, and their weapons were mainly spears, throwing axes, and swords for short distances. In Casillinum, Narcissus placed infantry and infantry archers in the center. When they stepped back due to Frank's attack, Narces attacked the Frank's side with a cavalry that was on the side. This attack stopped the Franks and they immediately turned their heads outward to respond to the lateral attack. However, Narces, who knew that the Frankish formation was too solid to be crushed by shock, approached them instead of having cavalry use their bows outside the enemy's fighting range. This was because intensive shooting forced them to dissipate dense formation to reduce damage. Finally, when the Franks left the formation and dispersed backward, Narces seized an opportunity to attack the enemy's center. In this way, the enemy avoided being exterminated with a timely attack.
