At the same time as the fierce battle under the unification of Wancheng, in front of Chang'an City, there was also a lot of war, and Gonghe Lianding and Northern Wei Sikong Xijin of the Great Xia Kingdom Plain led their armies and fought fiercely.
Helian Ding originally thought very well, the defense of Tongwancheng City was strong, although it was besieged by Northern Wei, but it should be held for a period of time, there should be no problem, he took advantage of this time, first captured Chang'an City, and then led his army back to aid Tongwancheng, inside and outside, defeated the Northern Wei army. However, Xi Jin was also a famous general of the Northern Wei Dynasty, with extraordinary troops, both attack and defense, the two sides faced each other for several months, although they failed to defeat the Great Xia Army, they could use the advantages of the defenders, using the city defense of Chang'an City, and the Great Xia Army could not gain any advantage.
At this moment, Tongwancheng was captured, and the news of Helian Chang's escape to Shangyi came, and the Great Xia army in front of Chang'an City was suddenly confused, and Helian Ding did not dare to wander under Chang'an City any longer, and hurriedly led his army to withdraw from Chang'an and go up to Join Helian Chang. Xi Jin led his army to Yongcheng, and then returned victoriously.
Because the time for the large army to come out was not short, and fearing that the rear was unstable, the Ruoran troops came to invade, so after occupying Tongwancheng, Tuoba Tao planned to temporarily slow down the attack on Helian Chang, and the Banshi returned to the dynasty. However, Xi Jin insisted on taking advantage of the victory to pursue and completely destroy the Great Xia Kingdom. In the end, Tuoba Tao sent Xi Jin 10,000 reinforcements, while leaving the generals E Qing, Qiu Dui, Liu Ba, and others as Xi Jin's assistants to attack the remnants of the Great Xia State.
Then, Tuoba Tao appointed tuoba generals, tuoba su the king of Changshan, as the general of Zhengnan, and stayed behind to guard the city of Wancheng, along with Jin Wuhuan loans. After arranging everything, Tuoba Tao led a large army and returned to Pingcheng.
Sure enough, Before Tuoba Tao reached Pingcheng, he got the news, and the Rouran Department took the opportunity to invade Yunzhong County. However, after learning the news that Northern Wei had conquered Tongwancheng and Tuoba Tao had returned with his army, the soldiers and horses of the Ruoran army quickly withdrew.
Everything went well on Tuoba Tao's side, but the Progress of the Northern Wei army pursuing the remnants of Emperor Helianchang of Bactria was extremely difficult.
The Northern Wei general Wei Pingbei (尉眷) took the lead in reaching Shangyi and launched an attack. Helian Chang was horrified and retreated to Pingliang. Soon, Xi Jin led the Northern Wei army to Anding, and joined forces with various soldiers and horses led by Wei Ju, Eqing, Qiu Dui and other generals to temporarily garrison Andingcheng.
Worse, plague began to circulate in the Northern Wei army, and a large number of warhorses died. The Mobility of the Northern Wei Army was almost lost and it was in a very passive state.
To make matters worse, soon, the Northern Wei army could not receive food and grass, and the soldiers had to suffer from hunger and hunger, and their morale was very low.
Xi Jin had no choice but to order a deep ditch and a high fortress, mainly defensive, and at the same time sent Qiu Dui to lead some soldiers and horses to go out to grab grain.
When Helian Chang heard the news, he was overjoyed and immediately organized his men and horses to launch a sneak attack on the Northern Wei army that was grabbing grain. The Northern Wei army was not vigilant, and Qiu Dui's troops were almost completely destroyed by the Great Xia Army, and Qiu Dui only led hundreds of remnants of the defeated generals and fled back to Anding City.
At this time, Helian Chang rose up arrogantly, led the soldiers and horses, stationed under the city of Anding, and constantly invaded, and the Northern Wei army was worried all day.
The Northern Wei military supervisor Yu Shi Anjie suggested that we should not just defend, but should look for fighters, take the initiative to attack, and strive to capture Helian Chang in one fell swoop.
Xi Jin, on the grounds that the warhorses were insufficient, insisted on sticking to help and did not agree with An Jie's suggestion. An Jie had to secretly plot with the lieutenant, prepare a small number of elite cavalry, and wait for the opportunity to move.
A few days later, Helian Chang personally came to call for war. An Jie also did not ask Xi Jin, and directly led his army to Kaicheng to meet the battle.
Helian Chang was triumphant and personally went out to fight An Jie. The generals of the Northern Wei Army recognized Helian Chang and were very excited, and rushed forward to besiege Helian Chang.
Helian Chang was astonished, so many people, how to resist ah? So he hurriedly turned the horse's head and fled. An Jie led his army in pursuit. The main force of the Great Xia Army was stunned in the rear, and there was no time to rescue it.
While chasing, the war horse ridden by Helian Chang suddenly lost its front hoof and fell to the ground, and Helian Chang was thrown heavily to the ground. Before Helian Chang could get up, An Jie had already led his army to kill and capture HeLian Chang alive.
The Great Xia Army was suddenly in disarray. Fortunately, Helian Ding, the King of the Plains, was also in the army, and hurriedly collected the remnants of the defeated generals and withdrew to Pingliang City. Subsequently, Helian Ding took the throne as emperor at Pingliang City. This time, it was February 428.
Helian Ding was also the son of Helian Bobo and the younger brother of Helian Chang.
After Helian Chang was captured, he was quickly escorted to Pingcheng and handed over to Tuoba Tao for handling.
Tuoba Tao not only did not kill Helian Chang, but gave him a very high standard of treatment, and even showed relatively closeness and trust to Helian Chang. However, Helian Chang was not at ease, and in 434, when HeLian Chang betrayed Northern Wei and was preparing to flee, he was captured and killed by Northern Wei generals.
Of course, Tuoba Tao would not forget An Jie and Wei Jue, who had made great contributions, and added An Jie as the General of Jianjie, the Duke of Xiping, and the General of Ningbei and the Duke of Yuyang.
An Jie and Wei Were rewarded for their meritorious service, but Xi Jin was ashamed and uneasy, and had no place to accommodate himself. He was the commander-in-chief, but he was frightened by the enemy's military might, and his own generals captured the enemy emperor, which made him face his generals and how to go back to see the emperor Tuoba Tao? Xi Jin, who was extremely embarrassed, hastily ordered all the armies under his command to abandon their heavy weight, carry only three days' dry food, advance lightly, quickly kill Ben Pingliang, prepare to conquer Pingliang City, and capture Helian Ding.
Unfortunately, after the two large armies engaged, the Great Xia army, which was originally preparing to flee, accidentally learned of the Northern Wei army's lack of food and water because of a mistake and defected to Bactria because of his mistake, Helian Ding immediately organized a large army to counterattack, surrounded the Northern Wei army, and blocked the retreat of the Northern Wei army.
The Northern Wei army had neither grain nor grass nor rescue troops, and quickly collapsed, and Xi Jin, EQing, Liu Ba, and other senior Northern Wei generals were all captured alive by the Great Xia army, and the soldiers were killed and wounded.
When Xi Jin led his army to attack Pingliang, he left the general Qiu Dui to guard and defend the city of Anding, guarding the heavy supplies. Unfortunately, when Qiu Dui learned the news that Xi Jin and the others had been defeated and captured, he was frightened, gave up his weight, and fled back to Chang'an City in one breath.
This is not to mention, after fleeing to Chang'an, Qiu Dui seduced Tuoba Li, the king of Gaoliang, who was guarding Chang'an, to abandon Chang'an City and flee to Pusaka.
The Bactrian army turned defeat into victory and reoccupied Chang'an City.
When Tuoba Tao heard the news, he was furious and immediately ordered An Jie to kill Qiu Dui, and then with An Jie as the main general, he guarded Pusaka to resist the attack of the Great Xia Army.
Although Helian Ding won the victory, after all, Bactria's strength was greatly damaged, and Northern Wei was far from the point of breaking his bones, so Helian Ding took the opportunity to ask Northern Wei for peace, tuoba Tao sternly refused, and ordered Helian Ding to surrender.
Helianding certainly could not have surrendered so inexplicably.
So the two sides continued to confront each other in the Guanzhong area.
