Fang Yuan stayed in Cao Huachun's old mansion for three days, and then immediately set off to Tianjin Weijun Port.

Tianjin Wei is one of the four major military port guards of the Ming Dynasty, and it is also the maritime gateway of Gyeonggi, with a fleet of 30 warships and 80 transport ships in Tianjin.

After Fang Yuan arrived in Tianjinwei, he directly took over all the warships of Tianjin Wei with the holy decree and the military order of the Governor's Office of the Five Armies, and ordered Fei Cheng, the commander of Tianjin Wei, to set sail for all the warships of the military guards and sail to Weihaiwei, which is only separated from the Bohai Strait from Lushunkou.

Five days later, the fleet led by Fang Yuan and Fei Cheng arrived in Weihaiwei, and at that time, Shi Lang's fleet, the Xuanjia Iron Cavalry of Chigutai, had already been waiting in Weihaiwei for many days.

Fang Yuan spent two days in Weihaiwei and thoroughly reorganized the naval divisions of Tianjin Wei, Weihaiwei, and Jinshanwei, with a total of 93 warships and nearly 200 transport ships. A fleet of this size may be far inferior to Zheng Zhilong's huge sailors, but it is more than enough to deal with the poor sailors of the Manchu Qing Dynasty.

In order to boost the morale of Tianjin Wei and Weihaiwei's army, Fang Yuan abandoned the original plan of integrating into a fleet. After referring to Shi Lang's suggestion, he temporarily changed his strategy and did not assign Fei Cheng, the commander of Tianjin Wei, and Liu Sheng, the commander of Weihaiwei, to Shi Lang's command.

Instead, the three fleets belonging to different fleets were divided into three routes, among which Shi Lang's Jinshan Guard Water Division and Liu Sheng's Weihai Wei Water Division were divided into two lines to flank the Manqing Water Division at Lushunkou. Fei Cheng's Tianjin Guardian Division escorted 200 troop carriers, carrying 8,000 Xuanjia iron cavalry and 20,000 war horses to land at Sanshan Haikou.

After that, the Tianjin Weishui Division cut off the way for the Lushun Shui Division to flee eastward, and the Xuanjia Iron Cavalry blocked the way for the defeated troops to flee north, in order to completely annihilate Shang Kexi's sailor division at Lushunkou. If it's gratifying to be captured alive, that's the best.

The so-called Sanshan Haikou is the city of Dalian before the crossing.

Three days later, after judging the tide letter and the wind and waves were suitable for sailing, the three-way sailor crossed the Bohai Strait and marched to the Liaodong Peninsula.

In order to prevent the Han people from being settled in the northeast, reclaiming famine, engaging in ginseng picking, fishing and hunting, and other activities, the Manchu Qing Dynasty implemented a border ban policy in the entire eastern Liaodong region.

The so-called border ban policy is the construction of a 1,000-kilometer-long border wall in the eastern Liaodong region. There are dozens of side gates on the side wall, and dozens of sergeants are stationed at each side gate to check on pedestrians.

Because the Manchurian population is less than one million, the entire Liaodong region is vast and sparsely populated, and the most concentrated population is in the area of Shengjing, Liaoyang, and the old capital Hetuala. In addition to the 2,000 people stationed in the Han Eight Banners and the Manchu Qingshui Division, Lushunkou and Sanshanhaikou are almost uninhabited barren areas for thousands of miles.

Because since the Dongjiang Town of Mao Wenlong, the general soldier, was deserted, the Ming army did not attack the Liaodong Peninsula on a large-scale sea crossing operation. There has been no war in Lushunkou for more than ten years, and Shang Kexi has 2,000 people from the Han Eight Banners, as well as the main force of the naval division stationed at the Lushunkou Military Port, and only a few patrol warships have been set up in the Sanshankou in the rear, with less than 200 sergeants for defense.

When the main force of Fang Yuan's surprise attack arrived at Sanshan Haikou, the Manchu Qing naval division battleships noticed the abnormality, and they still couldn't believe the facts in front of them, the Ming army dared to cross the sea to fight!

The naval division of Haikou Port immediately sent four warships to intercept it, but it was a mantis arm as a car, and it was easily defeated by dozens of battleships of the Tianjin Guard Water Division in less than an hour.

The two hundred Han and Eight Banner sergeants at the port saw that the Ming army was menacing, and they dared to continue to resist, so they immediately abandoned the port. Some of these defeated soldiers went south to Lushunkou to report the news, and some went north to Yingkou to warn the inland, and the Ming army's iron cavalry landed!

Fang Yuan was not only fighting against the Manchu Qing Dynasty, but also fighting against time, racing against time to lead the Xuanjia Iron Cavalry to land, and after landing, he did not rest, and immediately divided the Xuanjia Iron Cavalry into two teams.

A team of 2,000 people, led by Chigutai, pursued and killed the Tartar soldiers who fled north to report the news, Fang Yuan also issued a harsh slaughter order, whether it was the sergeants of the Han Eight Banners along the way, or the Manchurians who met did not leave any behind, they were all slaughtered, and they were stationed and waited after breaking through the border wall.

A team of 6,000 people, led by Fang Yuan himself, went south, and cooperated with Shi Lang and Liu Sheng's second guard water division to attack Lushunkou from both sea and land.

A day later, when Fang Yuan's Xuanjia Iron Cavalry arrived at Lushunkou, Shi Lang and Liu Sheng's fleet had already started a fierce naval battle with Shang Kexi's sailors for a whole day.

Although the fleet is at a disadvantage, it is still supporting itself.

Garrisoned at the mouth of Lushun were 2,000 men with blue flags in the Eight Banners of the Han Dynasty, and the sergeants of these Eight Banners were all composed of Han Chinese who surrendered to the Manchu Qing Dynasty, and the eight Han people who first defected to the Manchu Qing Dynasty were Ren Gushan Ezhen.

The Gushan Ezhen of the Han Blue Banner is really Bayan, the first border general to surrender to the Manchu Qing Dynasty, the son of Li Yongfang, a guerrilla general of Fushun Qianhusuo. After Li Yongfang surrendered to the Manchu Dynasty, he made countless military exploits for the Manchu Dynasty, and was rewarded by Nurhachi to marry the daughter of Abatai as his wife, and was given the title of Shun Forehead.

The Eight Banners of the Han Dynasty in Lushunkou are far inferior to the Eight Banners in terms of armament and quality. Shang Kexi's sailors had been beaten by Shi Lang's fleet and were holding on, but they didn't expect that there would be Ming iron cavalry heading south from the direction of Sanshan Haikou.

The 2,000 men of the Eight Banners of the Han Dynasty immediately defended the military port, intending to resist stubbornly in the corner of the military port.

The combat power of Fang Yuan's Xuanjia Iron Cavalry is stronger than that of the Eight Banners Iron Cavalry, and the combat power of a few Han Eight Banners militia is not much higher than that of Zheng Jun, no matter how stubborn he resists, it is a dish for the Xuanjia Iron Cavalry.

Fang Yuan didn't say a word, and immediately ordered a forcible attack on Port Arthur.

Under the attack of sea and land, the Han inlaid blue flag in Lushun port only resisted for two days, and the whole army was defeated, with 1,300 killed and 700 captured, and Lushunkou was declared to have fallen.

Shang Kexi, who was in charge of the defense of Lushunkou, saw that the military port had been lost and the back road had been cut off, so he dared to continue to fight Shi Lang at sea, and immediately withdrew from the battlefield with the remnants of his warships. Because the sea and land in Yingkou in the north had already been firmly blocked by Shi Lang, he could only lead the remnants of several warships and flee east to Dandong.

When crossing the Sanshan Haikou, it was intercepted by the Weihai Weishui Division stationed here, and the only remaining battleships were destroyed in one fell swoop, and Shang Kexi, who was at the end of the road, could only abandon the ship and go ashore, and fled north under the cover of a hundred defeated soldiers.

After all, the Weihai Weishui Division was not good at land warfare, and after pursuing for dozens of miles, he retreated, so that Shang Kexi escaped by luck.

At Lushunkou, Fang Yuan ordered the Xuanjia Iron Cavalry to hurry up and recuperate, and only gave one day of rest.

Fang Yuan discussed with Shi Lang and other generals how to deal with the captured 700 Han and Eight Banner soldiers.

These soldiers of the Eight Banners of the Han Dynasty, although they are Han Chinese, are also the main force that invaded the Central Plains later, and Fang Yuan will never show mercy to this kind of brute who is a traitor and desperately bites his fellow clan.

He immediately ordered the four Niu Lu Ezhen captives of the Han Eight Banners to be escorted back to the capital by the sailor to offer prisoners, and the remaining 700 people were all beheaded, and the corpses and people were all thrown into the sea to feed the fish.

After executing the traitors of the Eight Banners of the Han Dynasty, Fang Yuan discussed with Shi Lang and others, and the next plan, the most important is the retreat plan.

Once the surprise attack is exposed, Huang Taiji will inevitably lead the army back to help and block the passage for the Xuanjia army to escape back to the sea. If there is only one way back to Lushunkou, once the road is blocked by the Manchu iron cavalry, the landing Xuanjia iron cavalry will be in a very dangerous situation.

Therefore, Fang Yuan's preset return port this time was not Port Arthur, but Dandong Port at the mouth of the Yalu River, and went south to Phi Island, where Mao Wenlong was once stationed, and then returned to Tianjin Wei by sea.

Fang Yuan spread out the map of the entire Liaodong Prefecture, pointed to the strongholds on the map, and explained to Shi Lang and the others the two sets of military plans for this northward advance operation and how to retreat.

Xuanjia Iron Cavalry went north from Lushunkou, passed through Gaizhouwei, and arrived at Haizhouwei.

In the first set of battle plans, if the Xuanjia Army captured Haizhou Wei, Huang Taiji had not returned from Ningyuan City to help, so he continued to attack Liaoyang in the north and went straight to Shengjing. Shengjing is the capital of the Manchu Qing Dynasty, since the defense is stable, Fang Yuan will never gnaw this hard bone, but after attacking the old capital of the Manchu Qing Dynasty in the east, Hetuala, he will pass through Dongningwei (Benxi) in the south and arrive at Dandongkou to land.

In the second set of battle plans, if the Xuanjia army captured Haizhou Wei, Huang Taiji could lead the army back from Ningyuan City in time, so he gave up going north to attack Liaoyang, and turned to Dongningwei (Benxi), and then returned south to Dandongkou to land.

After the Xuanjia Iron Cavalry attacked northward, Shi Lang led the Sanwei Naval Division to carry all the armaments, materials, grain and grass at Lushunkou onto the ship, and then went to Phi Island to rest, waiting for the Xuanjia Iron Cavalry to return to Fang Yuan at any time.

After Fang Yuan clarified the battle plans of all parties, he rested for a day at Lushunkou, and then led the Xuanjia Iron Cavalry to the north, preparing to attack the first station, Gaizhouwei.
