Historically, Li Shimin sent an envoy to order Gao Jianwu, the king of Goguryeo, to demolish the White Bone Jingguan and recover the bones of Sui soldiers who died in Liaodong before the battle, which was regarded by Gao Jianwu as a threat to Li Tang, so Gao Jianwu began to build a Great Wall from Fuyu City, which stretched to the seashore to defend against the attack of the Tang Dynasty army. Pen, fun, pavilion www. biquge。 info actually does play a big defensive role.

However, things are different now.

The construction of the Great Wall in Goguryeo was, in Xia Hongsheng's view, an opportunity. A proper, reasonable, and just right opportunity to develop the Datang Sailor!

Liaodong, including Goguryeo, the terrain is very complex, the mountains and rivers are intertwined, either the mountains and mountains, or the continuous water network, for Goguryeo, it is a natural barrier, for the Tang Dynasty, it will seriously hinder the advance of the battlefield, and the pace of the offensive.

On the contrary, if you use the waterway, you can drive straight into it, avoiding the unfavorable geographical environment of Goguryeo, Liaodong and the Tang Dynasty. At the same time, if the battle was carried out by sea, with the land route as an auxiliary, a feint attack on the front, and the naval division logging behind the enemy's back, it would be possible to form a two-sided attack on Goguryeo, so that it would be exposed to the enemy on the belly and back.

In the history of later generations, such a thing happened.

In the Korean War that year, the North Korean army once defeated the South Korean army and occupied nearly 90% of the land on the Korean Peninsula. But MacArthur's Inchon landing became the key to turning the tide. MacArthur believed that the Korean People's Army would push the Korean **** back from Seoul, and he believed that even with American reinforcements, the emaciated, inmobile, and poorly equipped South Korean army could not stop the North Korean army's attack, and he believed that only a decisive military action in the enemy's rear could improve the situation. Therefore, he hoped to land near Inchon to cut off the supply lines of the Korean army and render it incapacitated, so as to win the war. In order to complete this huge amphibious landing operation, MacArthur used the U.S. Marine Expeditionary Force, which has extensive experience in amphibious landing operations.

At that time, I **** Mao Taejo warned Kim Il Sung many times that the US troops would definitely carry out a forced landing in Incheon, and asked Kim Il Sung to make strict arrangements for Incheon to prevent the US troops from landing. However, Kim Il Sung, who lacked strategic vision and foresight, turned a deaf ear to Mao Taejo's warnings, and was finally forced to land by the US Marine Corps Expeditionary Force due to negligence in precautions and insufficient troop allocation.

The victory of the Inchon landings prevented the harsh winter of the American invasion farther north, cut off the Korean supply routes, exposed the Korean army to the enemy, and created the necessary conditions for the recapture of Seoul due to its proximity to Seoul. Therefore, the Inchon landing also became the key to turning the situation on the Korean battlefield, and since then, the Korean army, which had been in sight of victory, has been defeated and retreated, and finally retreated to the 38th parallel, while the US army pressed forward step by step, and finally crossed the 38th parallel in defiance of China's warnings, triggering the subsequent War to Resist US Aggression and Aid Korea.

This line of thinking is entirely emulable.

The land army made a feint attack on the front line, and the main force of the naval division landed after it by sea detour, and when the landing was successful, the two fronts would start a battle together, and Goguryeo would be attacked on the back of the enemy, the front was pinned, and the back was attacked, and the Great Wall built was useless, becoming the "Maginot Line" of Goguryeo.

Xia Hongsheng heard that Li Shimin was angry about this, and this was the reason for laughing.

"Sailor?" Li Shimin listened to Xia Hongsheng's words, suddenly laughed, and said: "If you want to destroy Goguryeo, you naturally have to use the water division to cross the sea and attack and disturb the aftermath." ”

"Your Majesty has you ever thought about ......" Xia Hongsheng said to Li Shimin: "Use the water master as the main force?" Let the frontal army assist the sailors? ”

Li Shimin withdrew his smile and frowned: "Take the water master as the main force?" ”

"Not bad. Use the sailor as the main force. Xia Hongsheng nodded, and then told Li Shimin what he knew about naval warfare.

Li Shimin has always attached great importance to Xia Hongsheng's views, because Xia Hongsheng can always look at and analyze a matter from a very advanced vision, or from a perspective that others will not remember, which can bring Li Shimin many views that make him feel refreshing, making Li Shimin's arrangement more comprehensive and perfect.

Therefore, when Xia Hongsheng told his views, Li Shimin listened very carefully and carefully, and the more he listened, the more Li Shimin's eyes lit up. Xia Hongsheng's words made Li Shimin see a completely new strategic way, not only to treat Goguryeo, but a combat method that is different from the current Tang Dynasty, and a huge improvement and supplement to the current Tang Dynasty's combat mode, a new form.

“…… Therefore, Your Majesty, we can completely establish a sea deterrent, use the weapons on the sea ships to capture the coastal cities, and then carry out landing operations, relying on the coastal cities, using the sea ships to quickly launch a large number ......of land forces to advance, and maintain the superiority, so that Goguryeo cannot distinguish whether the land front is the main force or the sea ships are the main force, and the belly and back are attacked by the enemy, and the front and rear are not considered to be the front, and the front and rear are not considered to be the front, and the front and rear are not concerned, and they can only divide the troops, but both sides are weak."

Li Shimin nodded frequently when he listened, and Xia Hongsheng also told Li Shimin his views on naval warfare.

"Therefore, when Wechen heard that Goguryeo was building the Great Wall, he laughed." Xia Hongsheng said to Li Shimin: "Your Majesty, the minister thinks that this is a very good opportunity to develop our Tang Dynasty sailors. Your Majesty, now our land army of the Tang Dynasty is almost invincible in terms of combat effectiveness. Even the lack of physique and physical strength has been compensated for by the superiority of weapons. However, on the other hand, the sailors are far from the army on land. Now, our Datang has been able to make the most advanced iron ship in the world, Gao Jianwu built the Great Wall to resist our Datang land soldiers, officially a suitable time, so that we can have a reason to develop the water division, and build the Datang Navy into a sea blade that is not inferior to the army! If my Datang can have a sailor no less than the army, then in the future, our Datang's hands and feet will grow a lot, Your Majesty, think about it, the land of Linyi, if it is from the land, it will require the army to cross Jiangnan Road, cross Lingnan Road, and borrow the six departments of Nanzhao, but if we have a strong sailor, then a fleet is enough! ”

Li Shimin narrowed his eyes and smiled: "Xia Qing is still playing with Lin Yiguo's idea?" ”

Xia Hongsheng nodded: "The so-called life is the word "eating and drinking" in the world, eating enough and dressing warmly are the basics of everything. Regarding dressing warmly, Weichen is already starting to think about it for His Majesty, about having enough to eat, we have many people in the Tang Dynasty, but we lack a few good granaries!
