On the tenth day of the first month of the sixth year of Yongli, Zheng Chenggong led the army north to Changtai County, trying to form a trend of beating dogs against Zhangzhou Mansion.

Zheng Chenggong's intentions were very obvious, and the defenders of Zhangzhou also understood it. On the seventeenth day of the first month, the army arrived near Xixi, and the Qing army of Wang Jin, Wang Zhigang, Chen Shangzhi and other troops who were trapped in the capital city of Zhangzhou gathered thousands of soldiers and horses to fight.

The strength of the Ming army was less than half of the Qing army, and the initial battle was unfavorable. Gan Hui fought hard and was hit by two arrows, Chen Feng followed, was injured by four arrows, and had the appearance of defeat.

At this time, the king of the Great Governor's Array, Kong Yan, supervised the officers and soldiers to advance bravely, and they were cut off when they retreated. The Ming army had strict military laws, and the soldiers had no choice but to return to fight to the death, and finally resisted the offensive of the Qing army. The battle situation fell into a stalemate, and then, Ou Bin, the deputy general of Qinding Town, led the cavalry to charge directly into the Qing army's large array, and beheaded two cavalry generals, and the Qing army was immediately defeated, and countless people drowned. Because of his merits, Zheng Chenggong changed the Liwu Battalion to Liwu Town, and the battalion general Chen Feng was the chief military officer.

In the first battle of Xixi, the Ming army won more with less and defeated the Qing army in Zhangzhou. The army continued to advance, and a few days later, the Qing army gathered thousands of soldiers and horses to break through the Rongqi town.

When the army arrived, Zheng Chenggong camped on the stone mountain outside the east gate of Changtai County, making ladders and siege equipment, and the towns were also besieging the county seat. The Ming army's successive victories in southern Fujian encouraged the local anti-Qing movement, and Chen Yun, the head of the Ministry of War, led thousands of righteous troops to attach, and Zheng Chenggong incorporated them into Zhang Mingzhen's former army of the Navy.

Approaching the county seat, the defenders did not surrender, and the Ming army attacked several times, but the city was never able to advance. By the second day of the first month of February, the siege of the city was strictly ordered, and Wu Shizhen, the general of the guerrilla battalion, took the lead and bravely climbed the city, and was killed by artillery. Zheng Chenggong used Huang Yuan to manage the guerrilla barracks. At the same time, he realized that a strong attack was not the best policy, so he moved to the north gate of the high port, dug a tunnel, and tried to break the city by collapse method.

The so-called collapse method is actually excavation and blasting. Tunnels were dug to the bottom of the city wall, gunpowder was buried, and the pits were sealed, and the power of gunpowder explosion was used to destroy the city wall.

On the fourth day of the first month of March, Zheng Chenggong received a military intelligence report, saying that Chen Jintong, the governor of Zhejiang and Fujian, and the governor of Zhejiang and Fujian, had come to the aid of tens of thousands of horses and arrived near Tong'an County. When the strong enemy approached, Zheng Chenggong had to order a blast, planning to enter the city if it was broken, and send reinforcements if it was not broken. As a result, on the morning of the seventh day of the first month of March, the gunpowder was lit, but unexpectedly, the tunnel did not reach the city wall, but only blew up a huge crater outside the city. So on the same day, Zheng Chenggong personally led the army to move to Jiangdong Bridge to intercept Chen Jin's army.

Jiangdong Bridge was formerly known as Hudu Bridge, built in the Southern Song Dynasty Shaoxi period, after repeated destruction and repair, to the Jiajing period of the Ming Dynasty, the new bridge was completed, "the stone beam is 80 feet long, the width and thickness are 5 feet each, there are 15 roads in the water, a three-beam, the sparse is wide, the slate stone is cross-bridged, the width is 20 feet, the length is 2,000 feet. "This bridge" is heavy and strong, and it is solid. It can't go up, it can't be angry, it can't be hot, and it can't be hot, and the hurricane can't tilt." It is a miracle in the history of bridge construction, and it is called the world's largest stone beam bridge for later generations.

This bridge is located in the lower reaches of Beixi on the Jiulong River, and has always been a traffic artery together with Zhangquan. Chen Jin led the army to help, and naturally he wanted to pass it.

After last year's three defeats in Cizao, Qianshan, and Xiaoyingling, as well as the two defeats in Zhangpu and Haicheng counties and the Qing army in Zhangzhou this year, the situation in Fujian has been reversed. Chen Jin was menacing, not only mobilized a large number of Qing troops from Zhejiang and Fujian, including the governor of Zhejiang and Fujian, but also summoned the Qing army from Tingzhou to the south, and at the same time used Zheng Cai's old generals Cai Xing and Zhang Yunfei to go out of Quanzhou and attack the left office.

Because Chaozhou was still in the hands of the Ming army, Chen Jin was not able to mobilize the Chaozhou Qing army to advance eastward as in history, but the Qing army in Guangdong had launched an offensive against Chaozhou earlier, such as Huang Yingjie and Zhang Daoying's green battalion at this time still continued to attack the Ming army's Luohe defense line.

In this regard, Zheng Chenggong sent Huang Xingdu, the chief military officer of Zhongquan Town, to guard Zhongzhen and Huang Wu's British barracks to camp in Nanjing and Pinghe to guard against the Tingzhou Green Battalion; Huang Dazhen, the chief officer of the guard Qianzhen, led his troops and horses to level Hou Zhou Hezhi with the rear army of the water division, the right army of the water division, and Hou Zhou Rui of Min'an to intercept the water division of the Qing army in Fujian; and sent Chen Liuyu's Beizhen and Xinwu battalions to assist in guarding Haicheng.

To ensure the defense of the key points on the periphery, Zheng Chenggong relied on the terrain to ambush the town of Zuochong and Qibing Town, the chief military officer of the right pioneer town, and attacked the Qing army in Zhangzhou; Rongqi Town, Zuo Xianfeng Town, Qinding Town, Liwu Town, Aid Zuo Town, Qianfeng Town, Zhengbing Camp and other departments were camped; to aid the ambush of the woods in the town, thinking that the towns should respond; To aid the right town to ambush the Shenqing Bridge and the area of Hongchuanwei, and intercept its way back.

According to Zheng Chenggong's arrangement, each town attached a mountain in front of it and a water back, and led the water division to return, cut off the back road, and imitate the method of Huaiyin Hou backing the water array. At the same time, the whole army was ordered to be rewarded and punished according to the enemy. In addition, Xu Du Array and Supervisor Battalion showed the retreaters below the deputy general on the spot, and led the retreaters of the general town to tie up the right to show the army before the army, making it clear that they wanted to fight Chen Jin to the death here!

On the tenth day of the first month of March, Chen Jin's army arrived and camped in Niuti Mountain. Here is still five miles away from the Jiangdong Bridge, the Ming army set up camp first, has cut off the road of the Qing army into Zhangzhou, and occupies the geographical advantage.

The news of Zhangzhou Mansion was cut off, and Chen Jin did not dare to stay here for too long, until noon on March 13, he personally led a large army to come. When the Qing army approached, Tanma saw that the camps of the Ming army were silent, and the main force did not dare to advance lightly. Until they reached the main barracks, they launched an attack and attacked the camp with troops.

The Qing army had moved, Zheng Chenggong immediately ordered, and the towns swarmed out. The Qing army met the enemy separately, and for a time the melee was on the spot, and it was difficult to distinguish the winner from the loser. So Zheng Chenggong personally led Rongqi Town to launch a fierce attack on the Qing army, and the Qing army was defeated, but there were few. Subsequently, Liwu Town, Qinding Town, Right Pioneer Town, Left Pioneer Town, and Aid Left Town all went out to fight bravely. At the same time, Hao Wenxing led the reinforcement of Zhongzhen from the woods and smashed into it, and the Qing army was defeated and retreated.

The Ming army pursued by victory, all the way to the camp of the Qing army in Niuti Mountain, all the towns gathered, continued to chase and kill, the Qing army was defeated again, Chen Jin abandoned his clothes and armor, and ran for his life. At nightfall, Chen Jin was chased and killed by the ambush soldiers of Huangshan, and retreated in a hurry, only to be spared.

In the battle, the corpses of the Qing army were all over the field, almost the whole army was wiped out, and the clothes and armor obtained were countless. According to the difference in the reward of the great enemy, Zheng Chenggong took Chen Feng of Liwu Town, Gan Hui of Qinding Town, Huang Ting of the Right Pioneer Town, and Huangshan of the Right Town as the first merit. Ascend to Huangshan as the premise governor, Gan Hui as the middle governor, Huangshan as the right governor, each governor under the left and right two towns. In addition, Liao Jing, the deputy general of the right pioneer town, was in charge of the right pioneer town, Ou Bin, the deputy general of the right Ding town, was in charge of the right town, and Yu Xinguan, the deputy general of the right town, was in charge of the right town, and the main barracks were changed to the regular soldier town, and the battalion general Chen Xun was promoted to the chief officer.

After the reward, the pig and sheep are slaughtered to celebrate the victory.
