Due to the outbreak of the war between Vygianod. The pressure on the northern defenses of the Svadia kingdom was greatly reduced. As a result, the Imperial army, which had been assembled in Uxhall for a counteroffensive, launched another expedition to the east to meet the invading Kugit forces.

By the time the army of the Khan of Gerak reached the city of Harma, the number of Kujit had reached 190,000, which seemed to be huge, but in fact, most of them were the clansmen of various small tribes who joined on the march, lacking unified command and equipment, and there were almost no heavy equipment for the project.

Therefore, Halma's defenders held out for nearly 7 days and finally broke through and joined Marshal Mars's 100,000 elite expeditionary force at Fort Redion. Neither Svadia nor Kugit rushed to attack, and Marshal Mars's expeditionary force, although small in number, was all elite troops of the Empire, including 50,000 cavalry of the Royal Knights and various lords under the marshal, 30,000 elite infantry, and 20,000 Imperial crossbowmen. Although the 190,000 people in Kugit are all cavalry, only the lancers and elite cavalry archers can really form combat effectiveness, a total of 90,000, and the remaining 100,000 people are relatively weak. Khan Gerak Khan ordered his cavalry archers to frequently harass the border patrols and villages of the Swadia Kingdom, which caused great trouble for the expeditionary force.

The mobility of the Kugit riders was much higher than that of the Imperial cavalry. It makes the Imperial soldiers taste falling into a situation where they can't catch up and can't fight. However, in several clashes of several thousands of men, Kugit was always discarded by the well-trained expeditionary force of the Kingdom of Swadia. In this way the war lasted for almost two years. The two sides have won and lost each other, and they have reached a stalemate.

In the autumn of 1235, several lords of the Rhodoc Mountains concluded a secret agreement in Aaron and decided to break away from the rule of the old empire. There were originally two main ethnic groups on the Karadia Road, namely the Rhodok and the Swadia, and the establishment of the Karad Empire unified the two peoples, but due to the limitations of the Rhodok Mountains and the lack of contact on the Sunoh Plain, and the Rhodok people have rebelled against the rule of the empire many times in history, the most powerful of which was the uprising led by Bjøstad in 1101, after which Rhodok was still subject to the empire, but obtained a high degree of autonomy. It also foreshadowed the establishment of the Duchy of Rhodoc in 1235. In the autumn of 1235, while the Imperial Expeditionary Force was fighting fiercely against the Kugits on the front line of Fort Redion, the lords of the Rhodok Mountains formed the Rhodoc Free Council and proclaimed that the Duchy of Rhodok was officially free from the rule of the old empire. In response to the possible suppression of the empire, Rhodok's envoys made contact with the khan before declaring independence.

Marshal Mars led his troops to retreat, and the Kugit naturally did not give up this great opportunity, so the army pressed in. After taking down Fort Reddian with ease. Believing that the supply of the Swadia army had been completely cut off, the Kugit began to continue the pursuit, and soon caught up with the marshal's army on the plains behind Fort Redion. At this time, the whole Kugit army believed that this battle would be decided. So began a full-scale pursuit, and these people were the marshal's bait. These so-called defeated armies are constantly discarding supplies, jewelry, armor, weapons, and so on as they retreat. Seeing this, the Kujits, who had launched the attack, immediately began to plunder, forgetting about the pursuit of the enemy. The scene of the collision between the rear and the front army of Kugit was very chaotic. At this time, the Imperial crossbowmen who were lying in ambush in the nearby forest of Alib began to shoot at the chaotic Kujits. The Kujits' defenses were difficult to withstand the fire of the Imperial heavy crossbows, and the casualties were very heavy, while the previous heavy infantry began to turn and kill, and the undisciplined Kujit began to flee in all directions. The fleeing Khan regrouped his army for a time, but the newly established position was scattered by the heavy knights of the Royal Knights. At this point, the Khan completely lost control of his troops, and fled with the remnants of the army in the direction of Fort Redion under the protection of Saiga. When the defeated army rushed to the castle, they found that the castle had already been captured by the roundabout Swadian army. They were greeted by Imperial light cavalry rushing out of the castle and a rain of arrows from the city. At this point, Qujit's army was completely routed and fled to Halma. Marshal Mars, fearing the presence of Rhodok's army in the rear, did not order a pursuit.

In this battle, Svadia defeated twice as many opponents as her own with its well-trained soldiers, and 70,000 Kugits under Gerak Khan were killed in a single day. Heavy casualties caused the tribes of the steppe to withdraw their tribesmen one after another. The threat of Kugit to the empire was temporarily alleviated.

However, the war was far from over. The marshal's troops, after a few days of rest, began an orderly retreat. When the army withdrew to the forest of Yalib, which had previously defeated the Kujits, another force appeared before them, this was the army of the Duchy of Rhodoc, the Rhodoc mobilization led by Field Marshal Griffos, a total of 60,000 men. This is almost half the strength of the Principality of Rhodoc in the sparsely populated region of Rhodoc. As a result of the agreement with Kugit, the lords of the Duchy of Rhodok generally believed that the Swadia Expeditionary Force, which was short of supplies in the face of Kugit's large army, was doomed. All they had to do was hunt down the remnants of Svadia's defeated army. But at this time, what they were facing was not a remnant of a defeated army, but an elite army with good discipline and victory. The two sides soon began to line up. The Rhodok Mountains once produced some of the Empire's finest crossbowmen, and the Rhodoc crossbowmen's siege crossbows were terrifying to their opponents in terms of power and range.

Marshal Mars first ordered his heavy infantry to charge the right flank of Rhodok's army under the cover of Imperial crossbowmen. While the infantry of the two sides made contact, he ordered Kraggs to lead 5,000 heavy cavalry to launch the first wave of assault on the left flank of Rhodok's army. Michod and Lafazi each led 5,000 heavy cavalry to launch a second and third assault on the left flank of the Rhodoc army. and assigned Count Disping to lead 10,000 royal knights back to the left flank of the Rhodoc army. Under the continuous onslaught of the Imperial heavy cavalry, Rhodok's left flank was finally scattered, and at the same time, the knights led by Count Disping plunged directly into the ragged left flank like sharp knives, and joined forces with the other three lords to start a massacre of Rhodok's infantry. Marshal Mars led the remaining cavalry to launch a general assault on Rhodok's army. Frontal breakthrough of the already terrified Rhodok soldiers. The fleeing Rhodok soldiers rushed to the Cressy Mountains, leaving behind more than 20,000 corpses. The Imperial Army, despite the infantry losses, suffered negligible casualties overall. In order to destroy the separatist forces, Marshal Mars decided to march his troops into the Cresy Mountains to encircle and suppress the remnants of Rhodok's army.

To Marshal's surprise, the fleeing Rhodok soldiers were regrouped under the leadership of a veteran. The veteran's name was Gruenward and he was a member of the Rhodoc Parliamentary Guard. In the army is the sergeant major of the Hawkeye Sniper. His Hawkeye Snipers, an elite unit of Rhodok's crossbowmen, have not lost their fighting spirit. The members are all excellent marksmen, and not only that, but they are also excellent samurai. In the previous defeat, Gruenward led his men to protect Marshal Graves and other lords who participated in the battle and retreated to the Kress Mountains and continued to gather the rout, and actually assembled an army of about 10,000 men. Within a month of Marshal Mars's entry into the Cressy Mountains to encircle and suppress the remnants of the Rhodok army, this force skillfully evaded the pursuit of the Swadians, and constantly attacked the lone patrols, causing great trouble for the Swadians, and the number of troops increased to 20,000 instead of decreasing. On October 20, 1235, the whereabouts of the troops were finally discovered by the marshal's troops.

Graves decided to fight the Swadians. He and Gruenward chose a steep slope near the village of Serindir and set up a position. The Rhodok army numbered about 25,000 men (15,000 Rhodok sniper crossbowmen, 10,000 Rhodok sergeants and Rhodok spearmen) in three groups, with trees and multiple trenches in front of the formation. Graves divided the force into three brigades, two in the front and one in the rear. Each brigade consisted of Rhodok snipers deployed on either side by Rhodok spearmen. In this way, in the front column of the entire formation there are not only crossbowmen in the middle, but also crossbowmen at both ends. The whole formation situation is generally an inverted V-shaped formation with the two wings forward. The commander of the left flank was Count Larouken, the right force was commanded by Count Jhemmer, and Griffos and Gruenward were in the squadron. The Swadia army had 80,000 men at this time (45,000 Imperial Knights, 25,000 Swadia hoplites, 10,000 Swadia crossbowmen). The battle began, and Marshal Mars ordered his troops to advance cautiously towards the Rhodok army, which was repulsed several times by traps and a rain of arrows from Rhodok's crossbowmen. Due to range and terrain problems, Svadia crossbowmen could hardly pose a threat to the Rhodok army. The stalemate on the battlefield led Marshal Mars to order the troops to suspend the offensive. The two sides entered a stalemate for the time being. The confrontation between the two sides lasted from early morning to afternoon. Suddenly, heavy rain began to fall in the Cressy Mountains. The already difficult mountain roads became more muddy, and the movements of the Imperial cavalry and heavy infantry in Swadia became more difficult, and the troops fell into disarray.

Rhodok's troops suddenly attacked down the mountain. The surprise attack caught the Swadia army by surprise, but the Rhodok army also left its previously trapp-ridden position. Under the leadership of Marshal Mars, the Swadia army quickly recovered from the chaos. A counteroffensive against the Rhodok army began. The entire battlefield was thrown into chaos. As time passed, the tide of war began to turn in the Swadians' favor. Rhodok's army was gradually in danger of being surrounded. At this time, Gruenward led the Hawkeye Sniper into the battlefield. Attack Swadia's generals and knights with precise crossbow arrows. In the chaotic crowd, Marshal Mars's banner stood out in particular eye-catching, and Marshal Mars, who was wearing heavy armor, also became the target of public criticism.
