Before the main force of the Wu army arrived in Jiangling, the Wu army's navy took the lead in attacking the enemy naval warships docked in the water village south of Jiangling City.

The naval forces of this era were generally not "professional" naval forces, but simultaneously engaged in both water and land warfare.

Especially for the southern army, because most southerners are familiar with water, every soldier can basically become a qualified sailor soldier.

In this way, basically an army can form a good naval army after getting on the ship and training it a little.

However, Wu's navy was composed of soldiers who fought on the water full-time.

A few years earlier, Wu had set up a special navy, but there was really no enemy to deal with at sea, and there was basically nothing to do except to crack down on pirates and smuggling ships.

Therefore, Yang Wu had no choice but to dismantle the navy, and some of them continued to carry out the task of fighting piracy and smuggling, while the other part went inland to form a special naval army.

This attack on Gangneung resulted in 8,000 sailors marching with the army, and although they sent their troops late, they arrived at Gangneung before the arrival of the main force of the Wu army.

On 17 February, the 8,000 sailors under the command of Sima Fu, the commander of the navy, did not stop at the waters of Jiangling without any stop, and took advantage of the southerly wind to pull up their sails and attack the enemy's water village at the fastest speed.

After rushing into the water wall, more than 30 ships at the forefront suddenly burst into flames and rushed all the way to the enemy warships docked on the shore.

The tactic of fire attack was not uncommon in water warfare, and it was with this that Zhou Yu won a great victory in the Battle of Chibi, defeating Cao Cao's army.

And now, Wu Guo's naval army also used this method at the first time.

However, unlike the Battle of Chibi, the strength of the Sun-Liu coalition army in the Battle of Chibi was far inferior to the Cao army, and at this time, the Wu army had an absolute advantage in terms of strength.

Most of the soldiers of the Jiangling Navy were used by Gao Jichang to defend the city, and all that was left was 3,000 people left behind to guard the water village.

Moreover, these 3,000 men were ordered to burn their ships and withdraw to the city if the enemy navy attacked in a big way.

However, these naval officers obviously didn't expect the attack of the Wu army to come so suddenly, so quickly, that they didn't even have much time to react.

Therefore, in the face of the fire attack of the Wu army, the Jiangling army soon fell into chaos, and the soldiers had no fighting spirit at all and were in chaos.

Those soldiers who were already on land were a little better, at least many soldiers gathered under the orders of the officers and began to prepare to attack the Wu army with rockets to cover those soldiers who had not yet landed.

But the soldiers who had been staying on the warship were completely panicked, and one by one they did not dare to resist at all, but quickly landed ashore and prepared to flee.

In just half an hour, Shuizhai was breached by the Wu army, and more than 1,000 enemy troops were taken prisoner, while the rest of the enemy troops fled back to the city in a hurry.

It was an extremely comfortable victory.

In fact, Gao Jichang didn't have any hope for the navy army at the beginning, and even he didn't have much hope for the Jiangling defenders themselves.

His real reliance was on reinforcements from Liang and Shu.

Even he himself has such an attitude, plus the main force of the navy has been transferred to defend the city before this, and the rest of the navy army has also been ordered to withdraw to the city, so naturally he is even more warlike.

In this case, it would be a strange thing if the Wu army could not easily achieve victory.

When he received the news of the victory in the water battle, Yang Wu had just settled down in the camp of Qin Pei in the east of Jiangling City.

After reading the battle story transmitted by Sima Fu, Yang Wu put down his Chinese book and smiled slightly, and opened his mouth to praise: "Sima Fu's attack this time is decisive, as soon as it comes up, it is a fire attack, and then the whole army attacks, and the enemy army is blinded at once, and the enemy army is taken down without any loss, he fought really well in this battle!" ”

Yang Wu was not surprised by the victory in this battle.

However, Sima Fu's attack this time was so sharp, which made him look up to this person.

After arriving in Gangneung, he launched a decisive attack without any pause or rest, and the tactics of fire attack were used as soon as possible, so that he could easily achieve victory.

This made Yang Wu see a decisive and fast general, so he opened his mouth to appreciate.

However, his praise caused some people to be dissatisfied.

"King, that Sima Fu is just a general, he can make the first achievement, how can the last general be inferior to him? The last general asks for orders and personally leads the troops to attack the city tomorrow! Wang Maozhang stood up and said loudly.

Qin Pei and the others were also a little unconvinced, and they all stood up and asked to take the lead in attacking the city.

Yang Wu smiled dumbly, and hurriedly reassured: "General Wang, generals, I just said it casually, the victory of the naval army is gratifying, but it is still the generals who decide whether our army can break through Jiangling!" ”

After hearing this, the generals' faces were much better.

Sima Fu was originally Qian Biao's subordinates, after the battle of Huzhou, those generals in the two Zhejiang provinces were either captured or killed in battle, and Qian Biao, who lacked good generals, promoted some young generals in the army to lead the troops, and Sima Fu was reused by Qian Biao in this way.

Later, after Qian Biao surrendered and Sima Fu returned to Huainan, although he was a general, his position was promoted all the way, and now he is the commander of the navy.

Sima Fu can be promoted so quickly as a general, which will naturally cause dissatisfaction among some veterans.

"Generals, Gangneung is a fortified city, and the siege of the city is not in a hurry, let's think about it in the long run!" Yang Wu hurriedly appeased the generals.

These veterans, when they usually serve as the main generals, naturally have to be cautious and cautious, and dare not be careless; However, now that Yang Wu personally led the troops, these generals only thought about making great achievements in front of Yang Wu, and did not think carefully about other things.

It is certainly a good thing that the generals are actively seeking to fight, but it is not good if they fail because of their eagerness to fight.

So after appeasing the generals, Yang Wu then said solemnly: "Since Gu has ordered the two generals Qin Pei and Wang Maozhang to be the governors of the left and right respectively, then the two generals must also shoulder their own responsibilities, don't just think about competing for credit, but forget your duties!" ”

Wang Maozhang and the others were in their hearts, and hurriedly replied: "The last general will obey the order!" ”

Yang Wu nodded, and continued: "In the past few days, the enemy army has either fled from the small towns we have encountered along the way, or they simply have no troops to defend. It can be seen that Gao Jichang has made up his mind to stick to Jiangling City, and for this reason he has given up all other areas. ”

"In that case, let's not care about those irrelevant areas, all the departments are ready, and in three days, the siege will begin, and the place to siege the city will be selected as the acropolis in the east of the city!"

Wang Maozhang suddenly became anxious, and hurriedly stood up and said: "King, our army's camp is in the north, if we attack the acropolis in the east of the city, won't it mean that all the departments in my northern camp can't use it?" Why not attack the Acropolis to the north of the city? ”

Yang Wu scolded: "What are you anxious about? This battle of Gangneung is obviously not going to end in a short time, and it will naturally be useful to you in the near future, I just hope that you will not let Gu down when the time comes! ”

Gangneung Fortress is not boxy in shape, but resembles an irregular rectangle in which the east-west direction is "long" and the north-south direction is "wide".

Before the war, Gao Jichang built an acropolis outside the east and west cities, and two acropolis outside the north and south cities, and used these six acropolis to arch the acropolis.

These acropolises were all located outside the moat and were connected to the main city walls by bridges.

Only after conquering the acropolis could the Wu army manage to seize the bridge over the moat, or manage to cut it off.

For the first attack, the reason why Yang Wu chose to attack the acropolis at the east gate instead of the two acropolis at the north gate was mainly due to the topography of Jingzhou.

In addition to the moat in the north of Jingzhou, there is also a natural river flowing through, the water surface is wider, even if the Wu army conquers the acropolis, but the difficulty of attacking the city from this direction will obviously be higher than the difficulty of attacking the city from the east gate.

The moat to the east of the city is relatively narrower, and its moat is less than seventy paces wide.

In addition, according to the previously set policy, dealing with the reinforcements of the Liang army in the direction of Xiangzhou was the primary task of this battle, so the attack after three days was just a trial, and then the siege would gradually be intensified, creating enough pressure on Gao Jichang and forcing the enemy reinforcements to come out.

At that time, Wang Maozhang's department, which was placed in the north of the city, would have to take on the heavy task of defeating the enemy's reinforcements.

Therefore, during this period of siege warfare, Yang Wu would not arrange too many tasks for them to ensure that they had sufficient physical strength.

Three days later, in accordance with Yang Wu's orders, the Wu army, commanded by Qin Pei, launched an attack on the acropolis outside the eastern city.

This attack was only a tentative role, and after a not too fierce battle, Qin Pei had a rough understanding of the preparations of the defenders, the morale of the enemy army, the ability of the enemy generals to deal with and other aspects, so the Wu army that ordered the siege of the city retreated in turn.

The next day, the official siege battle began.

However, unlike the previous temptation, this time the Wu army began to attack the four acropolises in the north, south and east of the city at the same time.

The reason why the four besieged cities were attacked at one time was, in the final analysis, to give full play to the strength advantage of the Wu army as much as possible, and also to create enough pressure on Gao Jichang.

However, specifically, Yang Wu made special arrangements, outside the south and north cities, two acropolises near the east city, and one acropolis outside the east city, these three acropolises were handed over to Qin Pei's department to be responsible for attacking; And Wang Maozhang's department was only responsible for the acropolis outside the north city, near the west city; As for the Acropolis to the west of the city, and the Acropolis outside the southern city near the west of the city, there was no attack.

The purpose of this arrangement was obviously to reduce the burden on Wang Maozhang's troops as much as possible, so that they would not be consumed too much in the siege battle.
