When Liu Zhang heard this, his heart suddenly moved, and he remembered the way the army of later generations crossed the river without bridges - pontoon bridges!

"It is extremely difficult to fill the river, if our army does not fill the moat, it can also enter the city of Gangneung safely, Gongming, how long do you think our army will attack Gangneung and how many casualties?"

Xu Huang thought carefully for a long time, and then said confidently: "The Jiangling garrison is only 5,000, and the rest are private soldiers, so there is nothing to fear, if our army can reach the city wall safely, my subordinates think that they can attack the city in one day, and at most they can annihilate the defenders in the city in two days, and our army's casualties will be about 3,000!" Just ......"

"Just what?"

"My lord, if we don't fill in the moat, if our army can reach the city wall as smoothly as it goes? Most of our infantry do not know the nature of water, and it is impossible to swim across. Even if the soldiers are given driftwood to cross the moat, but the soldiers in the water are completely unprotected and have no power to fight back, and they will be slaughtered by the enemy, I am afraid that our army will have countless soldiers falling in the moat! ”

Zhang Liao also said: "And the moat of Jiangling City is as wide as five zhang, if such a long ladder is built, the soldiers walk on it, the long ladder will inevitably bend, undulate and sway, it is difficult for the soldiers to pass at high speed, if the defenders block the long ladder with archers, I am afraid that the soldiers will also be hit by arrows and fall into the water." ”

Liu Zhang said: "I understand what you mean, I have a way to build a large area of bridges over the moat in a very short time and send soldiers to the other side!" ”

Xu Huang immediately said: "I don't know what the lord's plan is?" ”

Liu Zhang said: "Build a pontoon bridge!" ”

"Pontoon?" Xi Zhicai said.

"Yes, it's the pontoon!"

Xi Zhicai said: "If the enemy attacks it with rockets, once the pontoon bridge is burned, it will be difficult for the follow-up troops to advance, and the vanguard may be ......."

Liu Zhang was stunned for a moment, yes, why didn't he think of this problem? However, if you think about it again, the troops of later generations were still able to capture the enemy's city by using pontoon bridges to attack the enemy's city in the face of a rain of bullets and bullets, could he be helpless in the face of a city that had been "backward" for nearly 2,000 years? Never! Soon he thought of a way and said, "Jingzhou produces bamboo, right?" ”

"Producing ......" drama Zhi instantly understood.

"Then use green bamboo as the material to make a pontoon bridge, green bamboo is hollow, buoyant is extremely buoyant, and it is wet, the enemy wants to ignite, it is not easy!"

Guo Jiafu said with a smile: "The lord has a wonderful plan, if our army builds a large number of such pontoon bridges on the moat, Jiangling City can be lowered overnight!" ”

Liu Zhang said again: "Boning, immediately order someone to cut down bamboo, bundle a large number of pontoon bridges, remember, the pontoon bridge must be at least able to make five soldiers and soldiers advance side by side, and at the same time, each pontoon bridge must be able to carry thirty people without capsizing and sinking!" Xun Yu stayed in Chengdu, and Liu Zhang asked Man Chong to manage the logistics of the front line.

Full of favor said: "Yes, may I ask the lord how many pontoon bridges he needs, his subordinates have a number in their hearts, and they can arrange manpower!" ”

Liu Zhang thought for a while and said, "Prepare twenty in each direction, and another twenty more in case you need them!" ”

Man Zhong said: "Yes, my subordinates guarantee that it can be completed in two days at most!" ”

Liu Zhang said again: "Then there is no need to be too anxious, the transfer of troops in Xiangyang is not thorough enough, the current Jiangling is a bait in our hands, we can't take it down before its role is completely gone, before that, our army's attack will be mainly bluffing." However, the matter of making the pontoon bridge should be kept secret as much as possible, so as not to be probed by the defenders, if the enemy knows in advance and thinks of a way to crack it, after our army launches a general attack, it will inevitably cause a lot of losses to our army! ”

"My subordinates understand!"

"The Generals Will Do Their ......"

The generals immediately stood up and bowed solemnly.

"From tomorrow onwards, twenty catapults will be deployed at each gate, and from morning till night, I will bombard the city walls, and at night the gongs and drums will be sounded from time to time to remind the enemy to get up easily. In short, don't let the enemy live in peace for a moment, and the enemy army will be exhausted as much as possible! As a traverser, Liu Zhang wanted to experience the feeling of waking up thousands, even hundreds of thousands, hundreds of thousands, of people (the people inside and outside the city, and even the Yizhou army will inevitably be affected to a certain extent) in the middle of the night.

"Yes!"

After Jiangling's side decided to besiege but not attack, Lu Su and Gan Ning also ushered in his enemy, the 30,000 Jingzhou naval army led by Cai Mao.

On this day, Lu Su and Gan Ning were in the public security city and looked at a message from a reconnaissance ship: "A large number of enemy sailors are going upstream, and it is less than three days with our army. According to investigations, the enemy's naval army has 30 three-story boats, 200 boats, boats, and boats, as well as countless fishing boats, with an estimated strength of about 30,000. ”

Lu Su smiled, although the enemy was large, he didn't seem to be very worried, and said: "Wang Rui has made a mistake this time, hehe, 30,000 people, I'm afraid this is the entire strength of the Xiangyang Water Division!" ”

Gan Ning was even more disdainful, but he was only able to move freely on the Yangtze River with only 800 brothers, and said: "The Jingzhou Navy is vulnerable, and no matter how many people there are, it is just a mustard." When I crossed the Yangtze River, the Jingzhou navy army hid in the water village and begged for God, hoping that I would be merciful and not to trouble them. Now we have 20,000 elite sailors available, victory is like probing the bag, please order the general, the last general is willing to lead the headquarters of the navy to meet the enemy, this battle will be won and returned, from now on the Yangtze River do not hear the name of the Jingzhou sailor, if the battle is lost, the last general is willing to lead the army! ”

Lu Su said with a smile: "Xingba is brave, I know very well that I am also like Xingba, and I can't wait to annihilate the Jingzhou Navy Division as soon as possible and achieve fame." But now is not the time to completely annihilate the Jingzhou Naval Division, so I hope that Xingba will endure for a while, and when the time is ripe, he will try to fight again! ”

Gan Ning was puzzled and said, "Oh, why is that? ”

Lu Su asked rhetorically: "Xingba, what is the intention of the lord besieging Jiangling and not attacking?" ”

"This ...... Didn't the lord say it? It is necessary to encircle the point and send reinforcements to lure out the enemy troops in Xiangyang! ”

Lu Su nodded and said, "Yes, this is what the Lord will......"

Gan Ning said eagerly: "But isn't the defenders of Xiangyang mobilized now?" There are 30,000 sailors and 15,000 infantry troops! ”

Lu Su said: "Yes, the navy is all transferred out, but there are 30,000 to 40,000 infantry troops in the Xiangyang area, and now less than half of them have come out, especially the strength, if you can't transfer as many troops as possible out of Xiangyang, it will be difficult to attack Xiangyang in the future, so we can't be in a hurry, wait and see, as long as Jiangling is tight, Wang Rui will definitely continue to send troops south!" ”

"What does this have to do with our trolls? There is no water army in Xiangyang anymore! ”

"Now the enemy army is adopting the method of advancing by land and water, you say, if we wipe out Wang Rui's naval army, will Wang Rui dare to continue to send troops south to rescue Jiangling? Moreover, once the reinforcements who have already set out know that the naval army has disappeared, they know that it is difficult to support themselves, and they are likely to turn around and return to Xiangyang. Our army in the Dangyang area only has 10,000 people of General Zhang, and if the enemy wants to retreat, General Zhang is afraid that it will be difficult to stay. Once the troops who have already left the city have fled back, when our army storms Xiangyang, I don't know how many soldiers will die in vain! ”

Gan Ning nodded and bowed: "The last general understands, then let Cai Mao be proud for a few days, and when the time is ripe, hum ......"

Lu Su said: "Not bad! I decided to withdraw all the ships to the water village of Gong'an Harbor and hold on to it, in order to paralyze the enemy and increase the arrogance of the enemy, once Cai Mao thought that our army was afraid of its naval army and did not dare to fight with it, he would be proud and complacent, and as the saying goes, 'the proud army will be defeated', as long as the time is ripe, our army will suddenly kill and win a great victory! ”

Gan Ning said: "The general's words are reasonable, I would rather admire, I would rather obey the general's orders, please give the general's order!" ”

Lu Su Zhengse said: "Xingba, you immediately order all ships to be built, all of them return to the public security port to standby, and all departments are on strict alert to prevent the enemy from sneaking attack. No one is allowed to attack without our order, and anyone who violates the order is subject to military law...... Ordered someone to immediately report the situation of the Jingzhou Navy Division to the lord, and at the same time report our decision together, please make a decision! ”

"Yes!"
