Before Samudan set out, he took various measures to conceal his intentions according to the possibility that the Qiongzhou army of the Song Dynasty might repeat his old tricks and make a black hand on his own march, so he took various measures to conceal his intentions, and he was even more cautious on the road. Pen ~ fun ~ Ge www.biquge.info can be said that his ideas are good, and his work seems to be flawless, but Samudan still made the mistake of empiricism. In this era, the 'spy organizations' were not very established, and it was often before the war that businessmen, soldiers, and even monks and nuns were recruited as 'intermediaries' to reconnoiter and collect intelligence in enemy-occupied areas. As a result, these people are not professional, and even if they find out, it is difficult to quickly transmit information back.

However, Samudan did not expect that the Song Dynasty would have such a strange Zhao Yu, and he began to set up an intelligence agency while preparing for his own power, and invested a lot of manpower and financial resources as the top priority. After two years of development and construction, the internal tentacles have penetrated deep into the vicinity of various departments and important personnel of the DPRK, and externally they have penetrated into the coastal prefectures and counties and the important state capitals in the interior, and even most of them already have their permanent institutions.

What Samudan didn't expect was that the little emperor of the Song Dynasty, who they regarded as nothing, had long been alert to the Jinghu Navy's southward participation in the attack on Qiong, and even judged their marching route based on experience, so his work to conceal his attempt to go south was tantamount to waste. And in this era, how can it be so easy to conceal the whereabouts of the army mobilization, so their whereabouts have long been exposed, and they are constantly being transmitted back to Qiongzhou.

Another reason is Samudan's cautiousness, the serious point of which has gone mad, when suddenly attacked, so that it is cramped and improper, if he still insists on leading the army to force his way through the attack, with their strength the Song army will be difficult to block all for a while; Moreover, even if the road ahead is blocked, if they are willing to abandon the front army to block the sea lane, and the brigade retreats in time, the Song army will not be able to complete the encirclement and put them all in their pockets.

In addition, Samudan was worried that the Song army would find out that he had not sent a sentinel ship to reconnoiter the terrain in advance, so that he made a mistake in judgment, and did not know that the waterway between Xiwan and Longwan was extremely narrow, and it was difficult for large ships to pass, even if it was a medium-sized warship, it could only pass by a single ship at high tide, otherwise there would be a danger of running aground, so it was difficult for the Song army to assemble quickly for a while. But he made a mistake in judgment, thinking that it was a male breakthrough, and ordered a re-formation to protect himself, and if he was too cautious, he also lost the opportunity to escape......

"Are they stupid?!" Chen Renweng led more than 30 dragon boats of the Destroyer Army and the Brave Army to rush into the battlefield from the narrow waterway, and found that the enemy troops did not retreat in time as expected, but were huddled together in a chaotic manner, braving the fire of rockets to adjust the formation, which made him also confused.

As early as five days ago, the Qiongzhou side had received detailed information that the enemy's Jinghu naval army assembled in Yulin Prefecture was waiting for an opportunity to move south. Previously, according to His Majesty's assumption, Ying Jieyan had already sent people to conduct a comprehensive reconnaissance of Donghaizhou. The whole island is shaped like a butterfly, the east is the Leizhou Peninsula, the west side is Weizhou Island, which is the throat of the ship in and out of Leizhou. The longest part of the island is more than 60 miles, the widest part is more than 20 miles, it is a belt, the radius is more than 400 miles, it is the largest island around except Qiongzhou, and the Longshui Ridge above is the natural road sign for the ship to pass through here. The whole island is high in the east and low in the west, with plains in the west and plateaus in the east.

After several analyses, Ying Jieyan and others thought that in order to inflict heavy damage on the enemy's naval forces and shatter their plan of landing in Qiongzhou, they should also be able to carry forward the superiority of the Qiongzhou naval forces in long-range firepower and avoid the occurrence of annihilating the enemy by destroying 1,000 and losing 800 of themselves. In the end, they chose the Sai Wan waterway for the battlefield, which was narrow, and the southern shore was either a steep coast or a shoal, making it difficult for the enemy to get reinforcements from the infantry troops near the shore; In addition, the enemy did not encounter a battle after a long march, and seeing that Leizhou was in sight, he would inevitably relax his vigilance, which was conducive to an ambush.

However, the Qiongzhou Navy also faced a difficult problem, where to stand by so as not to be discovered by the first navy's sentinel ships, but it was convenient to quickly attack and launch a surprise attack on the enemy. After several discussions and reconnaissance at close range, Liu Zhu chose the ambush position on the left tail tip of the 'butterfly' on Donghae Island, that is, on the north side of Sai Wan Island. However, in order to ensure the safety of the Song army stationed on Weizhou Island, the Song army sent troops to be stationed here, hoarding grain and grass to meet the imperial court, strictly guarding the coastal defense, and preventing the Yuan soldiers from raiding.

After the Xing Dynasty withdrew, the Yuan army sent two hundred-man teams to occupy Xiwan and set up an inspection department to prevent the Song army from returning to prevent it. Therefore, if you want to hide here, you must destroy this enemy army without knowing it. With the strength of the Qiongzhou army, it can be said that it is easy to kill these two hundred-man teams, there are countless ways to let them die without even slag left, but it is difficult to destroy them without being discovered by the enemy troops on the other side, so that the enemy Jinghu naval army can still pass by as planned.

This time, the two sides thought of a piece, Samudan wanted to use the cover of wind and rain to hide his whereabouts and enter the sea smoothly, while Zhao Mengjin thought of using the cover of wind and rain to slaughter all the enemy soldiers on Sai Wan Island. So on the night when the storm first rose, Zhuang Siqi, the commander of the rear army, personally led a battalion of elite infantry to land in Xiwan, touched the enemy camp and killed the enemy army. Later, the camp was restored to its original state, and the clothes of the Yuan army stood guard for them, and the navy entered the ambush site under the guidance of the rear army in the wind and rain the next night, and at the same time, 2,000 rear troops landed in Xiwan to prevent the enemy from landing on the island in desperation, and they could also use rockets and ballistas to cooperate with the naval army.

Therefore, the battle of Donghai Island completed the pre-war preparations under the enemy's nose, and Ying Jieyan sat in Qiongzhou to command and dispatch, and Zhao Mengjin went to Baisha Water Village to prevent the enemy from escaping and attacking the island. Liu Zhu led the Lingao, Chengmai Naval Army, and the Destroying Front Army and the Brave Army to annihilate the Jinghu Naval Army. Jiang Xuan ordered the Baisha Navy to patrol on the north side of the strait to attack Thanksgiving Harbor, one to attract the attention of the enemy and not dare to send troops to help, and the other to deal with the East China Sea Island.

Liu Zhu's battle plan was that after the enemy's Jinghu Navy Brigade entered the Saiwan Waterway, the rocket boats of the Navy and the rear troops on the island would take the lead in launching a long-range attack to block the waterway. The Destroyer Army and the Brave Army under the command of Chen Renweng quickly passed through the waterway between Sai Wan and Long Wan, pursued the retreating enemy troops, disrupted the formation of the enemy troops, cut off their back routes for escape, and gave the main force time to destroy the enemy.

At first, both sides entered their roles according to the setting of the script, but in the blink of an eye, they were all messed up, Chen Renweng looked at the enemy troops huddled together for a while, and he didn't know what to do for a while, if he launched an attack, he would rush into the enemy fleet, but they were squeezed until there was only a finger-wide slit left, and the dragon boat became a dilemma when it entered, and it was impossible to get out of it, and completely lost its mobility......
