(The first update, ask for a red ticket)

More than 40 ships took advantage of the rising tide in the salt river at noon to open the North Water Gate and get out of the jam, which made the salt guards on the north bank nervous for a while.

At this time, the elite of the Jiangdong Left Army had already controlled the south beachhead of Haitang Stone Dam, and Lin Jian stood at the head of Shitang Beach, watching the Kou boat turn out of the estuary and go south on the shallow beach.

Standing on the bow of the loach, the extravagant flying tiger was wearing scale armor, and it was not very conspicuous under the support of the guards, but on a cloudless sunny afternoon, Lin Jian was only one hundred and forty or fifty steps away from him, so he naturally saw his slightly distorted face clearly in his eyes, and said to everyone behind him with a smile: "It seems that he really hates me to the bone!" ”

Behind him, Zhou Tong smiled heartily, how could the hatred of secretly snatching his wife make the luxurious young marquis feel right? This kind of joke cannot be said in public, and his mouth is a serious analysis of the enemy's situation, and he said: "The Kou boat went south in shallow water, probably to enter the mouth of the river, forcing the Jinghai Water Battalion, which I have the responsibility of guarding the mouth of the river, not to dare to send the whole division to participate in the battle here......

Cao Ziang looked at the Kou boat heading south in shallow water, and said: "Seeing that the Luxury Flying Tiger is doing this, it can be regarded as a semi-open direct control of the East China Sea Kou soldiers, and it seems that it will not be long before the Luxury family raises the flag of rebellion again......"

"Let him ......go," Lin Jian said lightly, turning around and walking down the stone pond.

This side has long been borrowed in the name of Song Xiaobo's Hecheng Commander, and all the grassland households in the coastal area have been withdrawn to the west, forming an uninhabited grassland with a depth of forty or fifty miles on the east beach of Hecheng, and stationed heavy troops at Jiangmentun in Nanjiao in the east to block the mouth of the river, and the Kou soldiers traveled south in shallow water by boat, which could not contain the Jiangdong Left Army at all.

Lin Jian didn't immediately mobilize the Jinghai camp at this time, but the extravagant Feihu divided his troops out of the fortress, although it was not yet the time to forcibly attack, but he could let go of his hands and feet to speed up the pace of blockading the Hecheng fortress.

Although the Salt River is more than 100 steps wide, after the tide recedes, there is only shallow water less than two feet deep left in the river.

The mud dam will be built to connect the north and south banks to form a whole, and the Jiangdong Left Army can support the salt protection army camp on the north bank. According to the established plan, Mao Wenjing could allocate part of his forces to restore the coastal outposts and beacon piers on the line from Sheyang to Hecheng in the north.

After the blockade of the Yunyan River, there was room outside the east gate for the Jiangdong Left Army to maneuver and insert, and it was easy to fight a war of attrition that was extremely unfavorable to the defenders.

Since Hao Feihu personally led his troops to the sea, the main responsibility of the remaining Kou soldiers was to defend the Hecheng Fortress, contain as much as possible the Jiangdong Left Army, and hold on until the situation on the southern front became clear, so that they could mobilize enough troops to relieve the siege.

Since the guards had this mentality, the Jiangdong Left Army was naturally able to let go of their hands and feet to rush to repair the trench wall, and the number of people requisitioned before the battle increased to 10,000 for a time.

In addition to the camp of the salt guard army on the north bank, the trench wall built by the Jiangdong Left Army on the south bank in six or seven days was more than 2,000 steps long, six feet thick and more than a foot high, and completely besieged Hecheng Fortress.

Under the auspices of Cao Ziang, the four barracks of the Chongcheng infantry camp were directly embedded in the moat.

First erect the fence wood wall, fill the triple soil and tamp it, build two zhang high, and then lay the green bricks outside the fence wood wall, lay four layers of green bricks to prevent rainwater infiltration, and build the battlement mouth wall on it.

Although the circumference of each garrison camp was less than two hundred paces, and the ridged walls were strangely shaped, and there were no more than three or four hundred elite soldiers stationed in the camp, they were unusually strong—for the construction of these four small camps, more manpower and materials were used than a trench wall that was more than two thousand paces long.

After the prismatic fortress was built, it formed a whole with the trench wall, and a small number of elite soldiers were stationed, which could not only completely block the Hecheng fortress, but also prevent the reinforcements from approaching and attacking from the periphery.

After the fortification system was built, it was necessary to completely surround the 2,000 soldiers of Hecheng Fortress, and leave more than 1,000 elite soldiers of the Chongzhou infantry battalion on the south bank to defend with 2,000 township soldiers, plus more than 1,000 salt guards on the north bank to defend the fortification.

The cavalry battalion can be used as a mobile combat force on the inner line of Chongzhou, and there is no need to be in charge of guarding the periphery of Hecheng Fortress.

Even Zhang Yan, who no longer understands military affairs, can see the intention of the Jiangdong Left Army to requisition more than 10,000 people to build a siege wall after inspecting the south bank fortification: after the war, Lin Jian only needs to further thicken and heighten the entrenchment on the basis of the trench wall, wrap the blue bricks, and open the city gate three or two times, and the Hecheng fortress in front of him can become a real Hecheng, and at this time, the siege is the inner city of Hecheng.

Lin Yan really unceremoniously took the defense area of the Jiangdong Left Army as his own territory, Zhang Yan was depressed and abnormal, but he had to admit that although Lin Lian's tactics consumed a lot of manpower and materials, it was solid and effective.

Not only was the autumn grain harvest and the construction of the new city in Chongzhou not so affected by this raid, but even the Hecheng Division Yamen, which was temporarily located in Xishutai, began to organize grassland households to mow grass and bale in the area near Xishutai - apart from Chongzhou, what other county could be so calm and unhurried under the threat of thousands of soldiers?

However, after Lin Jian entrusted all the military and political affairs of the northern front to Cao Ziang, it had been a few days since he left Hecheng, and even if Zhang Yan still had a fire in his heart, he couldn't find anyone else to vent.

The waves were like fury, hitting the bow of the ship and scattering into jade flowers.

In October, the monsoon gradually turns. At this time, the southeast and northwest winds alternate over the East China Sea, so it is very convenient to wait for the wind to go south or north.

Daheng Island, the main island of Shengsi Islands, is like a huge chicken paw lying on the sea surface one hundred and seventy or eighty miles east of Haiyu, and the Jinji Mountain at the west end of Daheng Island stands seventy or eighty zhang high, and it looks unusually majestic and majestic in the vast East China Sea.

After the boat division of the Jiangdong Left Army rose in the East China Sea, Luxury Feixiong carefully managed the Jinji Mountain stronghold on Daheng Island.

Donghai Kou at the lookout post on the north cliff of Jinji Mountain was the first to see a few sail mast black shadows exposed on the skyline of the north sea, and not long after, a huge fleet of ships appeared on the sea, even if you look at it from a very distance, you can feel that the ships led by this fleet are obviously several times larger than the sea ships on the side, and the long horn of the warning "woo" blows: "Enemy attack, enemy attack!" The warships of the Jiangdong Left Army are coming! ”

Su Tingzhan boarded the sentry platform, looking at the sea area to the north, his brows were slightly furrowed, compared with the Jiangdong Left Army Boat Division patrol in early August, the fleet of the Jiangdong Left Army Boat Division that attacked this time was much larger: there were as many as four large warships with a carrying capacity of 5,000 stones, and there were as many as 16 Jiyun-class warships, supplemented by 60 or 70 small and medium-sized warships such as Sea Loach, Sea Falcon, Cangshan, and Dayi, and the huge fleet was like a floating island on the sea, following the wind, and it seemed that it was rushing slowly and urgently towards Daheng Island.

At this time, the defenders on Daheng Island were only 3,000 people, and the number of small and medium-sized warships was only comparable to the number of boat divisions of the Jiangdong Left Army, not to mention the huge difference in the shape of the warships.

In particular, the two kinds of warships of Jiyun and Jinhai seem to be huge, but there are many more sail masts on the deck than ordinary sailing ships, and they travel by the wind, and the speed is faster than that of loach ships, the side walls of the ship are wrapped with iron plates, and the bow is equipped with iron ramming angles, and its own structure is extremely strong and has a strong impact ability at sea - there is no warship in Su Tingzhan's hands that can match it at sea.

In the past, he still wanted to win by the number of warships, but at this time, the whole division of the Jiangdong Left Army came over, and after seeing that the situation had been strengthened, the strength was afraid of no less than three or four thousand people, Su Tingzhan immediately dispelled the idea of going to sea to meet the battle, and ordered all the warships to avoid the inner harbor, and all the bed crossbows were transferred to the Jinji Cape Camp Fort, so as to increase the defense of the bay mouth and prevent the boat division of the Jiangdong Left Army from breaking through the blockade of the headland.

************

The division of troops in Hecheng of the Flying Tiger made Lin Tie also able to calmly withdraw troops from the northern front, and the cavalry battalion got out of the northern line and became a mobile combat force capable of the inner line, so Lin Tie was not afraid that the soldiers who would go to sea would dare to land and attack in Chongzhou, so he transferred all the Jinghai water battalions stationed at Jiangmen to block the mouth of the river and rushed to attack Daheng Island.

Once the Jiangdong Left Army used the boat division to expand the battle line to the outer line, the Hecheng Fortress, which was defended by 2,000 soldiers, became a solid place of death, and it was not a problem at all. However, the more than 2,000 soldiers led by Yu Feihu to the sea harassed more than other coastal prefectures and counties, but they did not pose a threat to Chongzhou, let alone compete with the Jinghai Sea Camp at sea.

As for the possibility that the extravagant flying tiger might break into the estuary of the river by Kou boat and invade Jiyang, Hailing and other counties upstream, Lin Jian was not worried. First, these areas belong to the defense of the water camp in Ninghai Town, and Lin Jian will not be kind enough to assume the responsibility for the defense of the water camp in Ninghai Town, and besides, if the Feihu really dares to go deep into the Yangtze River, it is not too late for the Jinghai water camp to return to the division to block the mouth of the river to catch turtles in an urn.

In fact, after the Luxury Feihu divided his troops and left Hecheng, he saw that the coastal area of Hecheng had become an uninhabited grassland and there was no opportunity to take advantage of it, so he continued to go south in shallow water to invade Haiyu, and burned the war to Ludong Gongzhuang, Haiyu, Jinhu and other counties.

The forest is like a mountain, and it is on the deck of the aft cabin of the Lijin Sea, overlooking the headland in the northwest corner of Jinji Mountain on Daheng Island.

Unlike the shallow mudflats along the coast of Sand Island, which are shallow mudflats and shallow mudflats, the surrounding large bedrock islands that are thirty or forty miles long are complex enough to make use of the coastal terrain to construct a complex defense system.

The stronghold of Donghai Kou on Daheng Island is mainly located at the northwest foot of Jinji Mountain.

There is a natural bay mouth that connects with the Seongshi Creek that flows down from Mt. Jinji on the island. Although Qingshi Creek is shallow, it forms a deep-water bay three or four miles long at the northern foot of Jinji Mountain, which is a natural sheltered harbor.

The mouth of the bay is full of reefs, and those who are not familiar with the waterways can easily break in, and there is a high chance of hitting the reef.

Entering the mouth of the bay, there is a headland island on the south coast. At low tide, the headland is connected with the shallows on the south shore, when the tide is high, the shoals are submerged, the headland divides the northern foot bay of Jinji Mountain into inner and outer harbors, the main channel on the north side is only more than 300 steps wide, considering that the underwater of the beach may lay a dark pile, the waterway that is really conducive to passage may be more than 100 steps wide.

The Tokai Kou built a fort on the headland of the harbor, like a giant spirit god guarding the inner harbor, and the giant arrows of the bed crossbow at the mouth of the fort battlement wall flashed with cold light, warning any enemy who tried to force the harbor to consider the price to be paid.
