The army changed its path, and Li Dingguo's eyes were the goal of this army.

Yanguan, located between the Lion Mountain and the Phoenix Mountain at the south entrance of the Xianggui Corridor in Xing'an County, northern Guangxi, the terrain is dangerous, the two sides are high mountains and mountains, and there is a passage left in the middle, and Yanguan is built in it. "It is really the throat of Chu Yue", and it has always been "the Lingnan war, which is tied to this".

It is not the only route between Guilin and the southern part of Huguang, but it is the most strategically important. Just as Li Dingguo thought, as early as June 15, the day before Kong Youde sent Li Yanghe and Sun Long to the north, he had already sent Zhang Sheng, the chief soldier of the Xisheng Battalion, and Guo Youming, the chief soldier of the Right Battalion of the Iron Cavalry, to lead the elite troops through the West Extension Port to Yanguan in order to jam Guilin's throat.

The so-called western extension is the resource county of later generations, and the elite of these two battalions passed through the mountains and sneaked south. By this time, he had already approached the side of Yanguan, but according to Li Dingguo's order, he was not in a hurry to attack the city, but waited for a good opportunity.

Li Dingguo's army marched all the way south and arrived near Yanguan on June 29. At this time, Kong Youde had received the urgent military information about the fall of Quanzhou, and hurriedly dispatched Guilin's troops to the north to rescue the Ming army's southward journey-Yanguan.

Zhang Sheng and Guo Youming, two generals who had been lurking here for a long time, seized Yanguan with a little means, and when Kong Youde's army arrived in a hurry, the Ming army was already waiting in the south of Yanguan.

Recapture Yanguan, you can defend the enemy from the outside, otherwise the Ming army can drive straight into Guilin from then on. This is the last thing Kong Youde wants to see, and it is also the goal that Li Dingguo is most eager to achieve. However, this time it was not the Qing army that was eager to recapture Yanguan, but the Ming army took the lead in attacking.

Heavy footsteps trampled the earth, not just the infantry marching in formation, but fifty tall war elephants like moving hills at the same time, and a sense of oppression spread over the surface. On top of the huge body, the drivers, archers and spearmen were condescending, ready to strike a fatal blow at the Qing army on the undulating mountains.

Behind the war elephants, the Ming infantry of the brigade swarmed around. Such a scene is rare among the soldiers of the Dingnan Domain from Liaodong and Beidi, and they were immediately stunned.

In the case of an ordinary army, the shock quickly turns into fear, and then collapses in fear. However, this feudal army was only slightly stunned after a long battle, and with the sound of war drums like rolling thunder in the clouds, it rushed forward in the face of the unstoppable momentum of the Ming army.

The formation changed, and the spearmen stepped forward and marched in formation. The cavalry of both sides retreated as the battle rapidly approached, and when they reached a hundred paces, a rain of arrows rose from the north and south.

The arrows swept a parabola through the sky, reaching the apex, and then turning into a storm that swept through the battle formations of both sides.

The Qing army is a veteran of the war for many years, and there is no shortage of sharp soldiers who followed the Great Western Army to fight in the north and south, even if it is those troops that have been expanded to Yunnan, born in the place where Tusi is everywhere, the people are fierce, and there is no lack of brave and ruthless people, the Great Western Army has been operating for many years, Li Dingguo has worked hard, and the first wave of attacks of the Qing army in the face at this moment is not half afraid.

The shield obscured the figure, the rain of arrows crackled on the shield, and occasionally there were screams, which only made the formation slow down a little. Among them, the rain of arrows of the Qing army was even more concentrated on those war elephants, but the skin was rough and the flesh was thick, and it was even more useless.

The formation of the two sides was still approaching step by step, and when they reached the interval of thirty or forty paces, while the javelins and axes were thrown, the war elephants accelerated sharply, and the infantry of the Ming army also rushed up with shouts.

The big thing charged forward, and the huge kinetic energy was unstoppable. The javelins thrown by the Qing army were finally able to kill the war elephants a little, but the pain was so painful, but it aroused the war elephants' temperament even more.

The war elephants rushed to kill, and the spearmen of the Qing army lined up to stab, but even people with guns knocked down and broke a large area. The forest of spears, which was usually indestructible in front of the cavalry, seemed to be just some thorns on the ground in front of such creatures, broken, trampled, and the thick trunk was thrown away, and everywhere they went, the soldiers of the Qing army flew in response to the sound, and slammed into the Qing army column behind the flank, knocking more Qing troops to the ground. The driver drove the elephants to attack, the archers with their bows and arrows, and condescendingly shot every Qing officer in sight, while the spearmen stabbed with spears, clearing the elephants from the flanks of Qing troops who might pose a threat to them.

The shock formation with the war elephant as the core even if the Qing army's large array rushed to a thousand holes, and the infantry did not fight without a formation, this is the iron law of soldiers, and the Qing army was in chaos, and at this time, the Ming army followed by the war elephant should rush up.

The spear stabbed straight and the sword flashed, losing the protection of the formation, and the casualties of the Qing army increased sharply under the rapid assault of the Ming army, and they were killed and wounded in just the moment of engagement. With the continuous advance of the war elephants, the Ming infantry of the mountains swept in.

This is the most common method of warfare to break the formation with war elephants, after the Great Western Army entered Yunnan, it obtained the war elephant as a troop, and soon organized the corresponding tactics.

At this moment, the Ming army, which was familiar with it, took advantage of the situation and constantly tore at the formation of the Qing army. The moment the battle actually came into contact, there was a situation that was unfavorable to the Qing army, which Kong Youde had never expected. However, he has been fighting for a long time and has a strong psychological quality, so naturally he will not easily choose to give up, or give up on himself.

The drums of war were beating, and the follow-up Qing army should launch a counterattack under the leadership of those experienced junior officers and veterans. The crowd of people rushing forward, the shouts of courageous forward, and the Qing troops in the front row of the retreating army looked around, all of them were affected by the whole, and even just under the impetus of the follow-up Qing army, they had to use a more violent way, with the momentum of a decisive counterattack to block the rapid advance of the Ming army.

Gradually, the momentum of the Ming army's attack was slowed down by the Qing army, and the battle re-entered the stage of stalemate.

This rhythm was what the Qing army wanted to see the most, because they had more veterans of battle and were more tolerant of casualties. Sure enough, as the battle progressed, the offensive momentum of the Ming army became lower and lower, and soon, there was a war elephant under the control of the driver who was attacked by the Qing army's archers, and there was a retreat action.

The army can only achieve victory if it advances, and the war elephant is the arrow of this army, and it is also bold, as soon as the war elephant retreats, the army's spirit will be shaken, and then it will be defeated. At this moment, under the banner of Shuai, Li Dingguo looked at the big banner with the face in the distance, his eyes blazing. He had already seen everything in front of him, and he had also recognized the strong combat power of the soldiers of the Dingnan Domain, and he had fought to this point, and he could not tolerate the slightest hesitation.

"Chop the hand, beat the drum, and go again!"

The order was given, and the war elephant that retreated to the edge of the Ming army's formation, the archer, who also had the right to command, put down his bow and arrow, pulled out his waist knife, slashed the driver with one sword, and then took the reins from the driver's hand.

The head of the rider was raised high by the spearmen, and the warlords shouted the order to advance, and when the rhythm of the war drums entered the attack zone again, feeling the threat of life, the pilots drove the war elephants forward desperately, and the Ming army battle array surrounded by the war elephants also launched a new round of onslaught under the leadership of the arrows.

With this new class of troops that destroyed the formation like a bag, the offensive of the Ming army was very strong from the beginning. Kong Youde relied on the bravery of his own soldiers and horses, and while paying a large number of casualties, he also resisted the first wave of attacks. If, according to the normal trend, the Qing army stabilized the formation and gradually launched a more ferocious counterattack, prompting the defeat of the Ming army, then there is no doubt about the winner. However, when the Ming army launched an offensive again, and it was a more fierce offensive under military law, the Qing army, which had already fought back desperately, wanted to re-stabilize the front, but it was already extremely difficult.

After a short period of twists and turns, the battle has returned to its original rhythm again. The Ming army continued to tear apart the formation of the Qing army with the blessing of war elephants, and the casualties continued to rise, but there were mountains on both sides, and Kong Youde had no other way. And with the first turn of the rout, the battle formation of the Qing army quickly collapsed when there was no hope of victory.

"The elephant also broke through, the king ran away, the death was incalculable, and the corpses were everywhere", this is the final account of this scene in the history books, but it is only the beginning at this moment.

The Qing army was defeated, and under the drive of the Ming army, countless Qing troops fled towards the Darong River in the south. Kong Youde had already reacted at the first moment of the army's rout, and led the 3,000 cavalry under his command as a reserve to move forward first. However, he did not plan to flee back to Guilin City, but planned to use these 3,000 cavalry to slow down the pursuit momentum of the Ming army. Because, even if he defends the city, he needs more troops.

The defeated Qing army fled for their lives, and the Ming army chasing behind them could no longer care about any formation, and it became the only thought in their minds to catch up and kill the Qing army on the spot.

This was the opportunity that Kong Youde had been waiting for for a long time, when he came out of a place near the Great Banyan River that was far away from the rout. The surging torrent swept in, and Kong Youde, with his rich combat experience, had even foreseen the chaotic Ming pursuers fleeing in a hurry under the iron hooves.

But at this moment, a group of war elephants in the distance ran with heavy steps. Not far away, a loud and terrifying neighing sounded, and the Qing army's war horses had never seen such a sound, and when they hurriedly stopped in fear, they immediately made a mess despite the orders of the cavalry. And at this time, in the distance, the war horses of the Ming army, who had long been accustomed to the existence of war elephants, rushed over and took Kong Youde's handsome banner!
