Lying in front is the main island of the Shengsi Islands, Daheng Island, which is a large island that is long and narrow from east to west and narrow from north to south, extending nearly 20 miles wide from east to west, and the north-south depth of the westernmost point is four or five miles, but the long and narrow east is like a halberd stretching into the blue water.

Jinji Mountain, the highest peak of Daheng Island, is also located at the west end of the island, with a height of seventy or eighty zhang, Lin Tie stands on the deck of the Jinhai, looking at the lush Jinji Mountain, and the dock fort wall built by the mountain looms among the mountains and forests. In the past sixty or seventy years, the Shengsi Islands have always been a pirate nest in the East China Sea, repeatedly suppressed, often there are big Kou entrenched on Daheng Island, Jinji Mountain's dock is also impregnable, only one or two thousand elite soldiers are to be defended, if you want to forcibly use troops, it is three to five thousand soldiers and horses pouring up, even if you do not count the casualties, it is difficult to suddenly attack.

At this time, in the bay at the southern end of Daheng Island, more than a dozen pirate ships came out one after another, mainly six loach ships, and the periphery was dominated by small Cangshan ships as sentinel ships, which quickly sailed towards this side of the fleet, wanting to expel them, and the deck was full of soldiers.

The soldiers all wore uniform red uniforms, half of them wore various types of armor, and all kinds of flags planted on the mast, bow and fenders were neatly and densely, and the military appearance was far better than that of the Donghai Kou during the bloody battle of Jiyang last year. It can be seen that the extravagant flying bear, who is alias the East China Sea Harrier Yuan Tingdong, has been very effective in integrating the East China Sea Kou in the past year, at least putting the Kou soldiers of the Shengsi Islands directly under his command and direct command.

The military appearance is not strict or not, to a large extent, it is to observe the flag, so when fighting, it is often used to increase or decrease the flag to confuse the enemy's sentinels. The Jiangdong Left Army was reorganized into nearly 7,000 people, including the commander's banner of Lin Tie, and a total of 712 command flags, general flags, battalion flags, and herald flags. Even if Lin Tie repeats the battle in actual combat training, rehearses battles, conducts light exercises, trains or goes to battle, he still regards the rectification of the flag as an important reference standard.

The Kou soldiers were in strict formation, and after leaving the island, they did not come directly to engage in the battle, but rowed upwind.

"The soldiers knew that the ship was small and not conducive to engagement, so they intended to have the upper hand so that they could seize the initiative." Ge Cunxiong watched the movements of the enemy ship and explained to Lin Jian that at this time, Zhao Qingshan issued an order to change the sails on another Jinhai-class warship, asking all ships in the fleet to compete with the Kou ship for the upper hand.

In addition to the Jinhai, the first battalion of the Jinghai Sea Battalion was reorganized and left Chongzhou with Lin Tie to patrol the sea, and the first battalion of the Jinghai Battalion was commanded by Zhao Qingshan, and when the formation went to sea, Lin Tie did not interfere with Zhao Qingshan's command, and his handsome flag was not raised on the Jinhai. In addition to the reorganization of the first battalion of the Jinghai Sea Battalion to patrol overseas with Lin Bin, 600 elite soldiers were still transferred from the Qinwei Battalion and the Chongzhou Infantry Battalion to take the Jinhai and Dongyang to form the escort of the Lin Bin, which was the main force to strengthen the patrol, so the deputy battalion commander of the second battalion, Ge Cunxiong, was transferred to the Jinhai and personally served as the commander of the two ships, Jinhai and Dongyang.

The patrol fleet consisted of two Jinhai-class and four Jiyun-class large seagoing vessels, which were extremely swift and large and sturdy, and the ships knew that they could never compete with the cruisers in the downwind direction.

The large sea ships of the Jinhai class and the Jiyun class have a carrying capacity of more than 1,000 stones, although the ships are equipped with large oars, and they are rocked by manpower, when they go against the wind, they are still far less convenient and fast than the light sea ships with complete sails such as loach ships and Cangshan boats, and it is easy to open up the distance when the wind is headwind, and it is difficult to launch an offensive.

Before the large-scale application of powerful long-range weapons in naval warfare, when water warfare was mainly based on broadside battles or direct collisions of ships, it was extremely important to seize the wind position. By seizing the upper hand, the Kou ships can effectively restrain the large sea ships of the Jinhai class and Jiyun class from playing a role in naval battles.

In addition to the six large seagoing ships as the main force, the patrol fleet still has nearly 20 small and medium-sized fast warships, such as loach ships, Cangshan ships, ship ships, and large-wing ships, which are not necessarily smaller in scale than the Kou ships that go out of the island to engage in battle. When patrolling, these small and medium-sized warships are tied to the back of the large stern to save manpower, and at this time they are untied and scattered on the periphery, shuttling between the fleets, acting as escort ships and sentinel ships, making the tactical formation of the patrol fleet more flexible.

At this time, Zhao Qingshan gave the command ship of the first battalion of the Jinghai Battalion to seize the upper hand, and the fleet changed its sails and turned in a zigzag pattern, running in the opposite direction, almost three or four miles parallel to the Kou boat.

Song Bo stood on Lin Bin's side, watching the naval battle break out, and couldn't help but get nervous. Although the extravagant flying bear with the pseudonym Yuan Tingdong deployed a small number of troops in the Shengsi Islands, the size of the fleet was much smaller than that of the patrol fleet, and there was a lack of large sea vessels that could exert great power in naval battles.

The Jiangdong Left Army patrolled the sea to the Shengsi Islands, which was a serious provocation to the forces of the East China Sea Kou entrenched here, and the East China Sea Kou could not retreat on the islands without fighting, but their strength was not good, and there were too many disadvantages in going to sea to fight.

As long as they can entangle and delay time, if they can find an opportunity to capture one or two ships, they can drive back the patrol fleet that cannot stay at sea for a long time, and prevent the patrol fleet from continuing southward to harass the Tushan and Daishan islands.

Large seagoing vessels rely on the sail to go against the wind to seize the upwind position, and need to get out of the large "zigzag" to borrow the wind power, which is much slower than the oared boat that goes directly against the direction. The patrol fleet then formed an independent team of more than a dozen small and medium-sized warships, such as loach ships, Cangshan ships, ship ships, and large-wing ships, and seized the upper hand with the Kou ships, and the large sea ships of the Jiyun class and Jinhai class formed an independent team to walk out of a larger "zigzag" on the vast and boundless sea, hoping to go around the upwind direction and then take advantage of the wind to directly attack the Kou fleet.

Seeing that the patrol fleet was divided into two parts, and that it was not capable of eating the main fleet of the patrol ships, after watching the main fleet sail four or five miles away, he thought of splitting and attacking it, first eating the fleet of small and medium-sized warships, and approaching the intention of engagement.

This side only met with bows and crossbows, and when the ships approached within thirty or fifty paces, they used their sails together and sailed downwind to widen the distance between them and the ships, so as to avoid a scuffle.

Kou Chuan also knew in his heart that such entanglement would unconsciously drag them to the downwind direction, and once the main patrol fleet occupied the upwind direction, it would give them a head-on blow. This side also changed the sail and turned and continued to go against the wind, three times several times, delaying the speed of the soldiers and consuming the physical strength of the soldiers.

On the vast sea surface, the headwind does not borrow the power of the wind, and the physical exertion of the oarsmen is huge, and the three fleets of the two sides are entangled in the sea for about two hours, leaving the Daheng Island to the west for a distance of thirty or forty miles, and in the distance, you can see the large and small Yangshan Islands appear on the sea level, and the speed of the Kou boat finally slows down.

Song Bo stood on the deck of the Jinhai, and he knew that in addition to the five-mast 21 sails, the Jinhai was also equipped with eight large oars so that it could sail against the wind on the sea.

Under the main deck of the Jinhai, in addition to the bottom bilge of the ballast stone on the lowest layer, there is also a cargo hold and two layers of Tibetan cabins, from the bottom keel to the main deck where Song Bo is stationed, it is two feet and six feet high, and there are three layers of stern cabins at the tail of the main deck, and the aft deck is three feet high from the sea.

The oars are on both sides of the troop compartments under the main deck, and the gunwales are usually closed, and they are only opened when needed to lower the large oars into the water.

After the retrograde speed of the Kou ship slowed down, although the main fleet of the patrol still failed to gain the upper hand, at this time, the command ship where Zhao Qingshan was located changed its command.

Song Bo couldn't see the Jinhai under his feet, but he could see the gunwales on both sides of the other warships open, and the large oars several feet long stretched out and fell into the water. First borrow the sail to get as close as possible to the Kou soldiers, and then the eight auxiliary soldiers work together to operate a pair of large oars, and work together to rock the oars against the wind in the oar, and the speed of retrograde is still not as fast as the light Cangshan boat, but it is not slower than the medium-sized loach boat.

Seeing that before escaping to the big and small Yangshan Islands, the six loach ships could not get rid of the pursuit at all, so they adjusted their formation and turned to sail, wanting to take advantage of the wind to launch an offensive against the patrol fleet, and wanted to break away from the formation of the patrol fleet, so as to take advantage of the wind to escape in the direction of Daheng Island.

After the entire patrol fleet was strengthened, the total number of auxiliary soldiers added up to nearly 2,000, which was twice that of the Dejima Bandar soldiers, and the advantage of the warships was very great. Lin Tie was not afraid that the Kou soldiers would take over the battle, but he was afraid that the Kou soldiers would take advantage of the small and light boat to go around the sea in circles or cower on the island and not go to sea.

Seeing the Kou ships rushing towards them, the two Jinhai-class main warships first changed their sails and turned, getting out of the way to the sides, and took the four Jiyun-class warships as the main force of the broadside battle, supplemented by the loach ships and Cangshan ships, and entangled more than a dozen Kou ships. After more than a dozen ships were dragged downwind, the two Jinhai-class main warships changed their sails and turned, directly pressing the ships with the advantage of their tall hulls, and the arrows, masonry and clay pots filled with fire oil were discharged together to attack the Kou soldiers.

The Jinhai bit one of Kou Bing's loach boats, Zhou Tong and Ge Cunxiong personally commanded the battle on the main deck, and Lin Tie, under the escort of Ao Canghai and others, took Song Bo, Wang Chengfu and others to retreat to the aft deck and watch the entire battle situation.

Song Bo felt a pity for the Kou soldiers in his heart, although almost all of the Kou soldiers were recruited from the elite of the luxury family to be dismissed in the coastal areas of Eastern Fujian, and the combat courage was not much worse than that of the Jiangdong Left Army, and the armor was also good, but the gap between the two sides in the warships seemed particularly dazzling at this time.

The main deck of the Jinhai was nearly a foot higher than that of the loach ship, and it was so strong and heavy that it almost sank the loach ship directly, and several soldiers were caught off guard and fell directly into the sea. On the wide deck of the Jinhai, there are more than 200 auxiliary soldiers, mostly armed with bows and crossbows and bayonet guns, to attack the soldiers and prevent them from forcibly landing on the main deck; There are also more than 200 armor auxiliary soldiers in the two-story Tibetan cabin under the deck, the small hole string window is open, the bow and crossbow are fired, or the approaching Kou soldiers are attacked with guns and spears, and the aft deck is equipped with two bed crossbows to shoot at the distant Kou ships, on both sides of the Jinhai, there are two loach ships and two Cangshan ships to guard to prevent other Kou ships from encircling the Jinhai.

After about half an hour of entanglement and fighting, the Kou ships were not defeated, and the remnants fled in the direction of Daheng Island, and the patrol fleet took dozens of hooks to lock up the two loach ships and five Cangshan Kou boats, and after exterminating the stubborn Kou soldiers on these ships, they did not pursue the remnants of the Kou ships, but continued to change their sails and go in a zigzag shape, sailing against the wind in the direction of Dayangshan Island.

The big and small Yangshan Islands are the two westernmost islands of the Shengsi Islands, the two strongholds closest to Haiyu County in the East China Sea, and the easternmost land from Haiyu County, only seventy or eighty miles by sea, is the bridgehead of the East China Sea Kou to attack Haiyu County, and there are not many Kou soldiers entrenched. It is very difficult to capture Daheng Island, gather all the forces of the Jiangdong Left Army, in order to let go of a fight, but also to guard against the main force of the East China Sea Kou from the islands of Changguo County to help, the strength of the Jiangdong Left Army is still seriously insufficient, Lin Tie this trip to patrol the sea, mainly to clear the East China Sea Kou on the large and small Yangshan Islands.
