"The second method that Ben will say is actually very simple, and that is trebuchet!"

"Trebuchet? Was this helpful? And is it too late to build now? ”

Zhang Hao glanced at An Renyi a little strangely, everyone knows that trebuchets are a siege weapon, but once the trebuchet is a little troublesome to prepare, it takes a long time to manufacture, where do they have so much time now?

And he didn't know the power of the trebuchet, and he would definitely not be able to deal with a fortified city like Changzhou, unless it was the kind of counterweight trebuchet that Yang Wu used to attack Suzhou. Pen @ fun @ pavilion wWw. ｂｉｑUｇE。 ｉｎｆｏ

But Yang Wu has a very strict control over the construction technology of the counterweight trebuchet, not to mention Tian Yan and An Renyi, two people who have long been on the "blacklist", even Zhang Hao has no chance to get it.

"Ordinary trebuchets are naturally useless, but what if it was the kind of Suzhou cannon that Yang Wu used to attack Suzhou?"

"Suzhou cannon?" Zhang Hao was a little surprised, the name of this "Suzhou Cannon" was also named because Yang Wu used a counterweight trebuchet to capture Suzhou in one fell swoop, and now it has long been famous.

"Not bad!" An Renyi said triumphantly: "Some of the craftsmen who built the Suzhou cannon were from my Runzhou, and the general secretly got the drawings through their family, so that the Runzhou craftsmen tried to make some of them, although the test could not reach the level of the Suzhou cannon that could fire more than 100 catties of boulder shells, but it could also fire 80 or 90 catties of stone bullets!" ”

The secret of the counterweight trebuchet was not complicated, although Yang Wu ordered it to be kept strictly secret, he also knew that it was impossible to hide it for a long time, but he didn't expect to be caught by An Renyi so soon.

"And what about time? Is it in time? ”

"No problem, the craftsmen in Runzhou not only made the Suzhou cannon, but also found that the Suzhou cannon can actually be disassembled into many parts for transportation. Ben built the parts of thirty Suzhou guns before the army, and today they have just been transported to the battalion, and it will only take a day or two to assemble them to launch a non-stop bombardment! ”

Zhang Hao was surprised and delighted, but he didn't expect An Renyi to even prepare a big killing weapon like the Suzhou cannon in advance. Although he did not witness the scene of Suzhou artillery bombardment of the Suzhou city wall at the beginning, he later heard the generals who had seen it say how spectacular the scene was, and the Suzhou defenders were defeated in just one day.

Obviously, this plan to attack the city with Suzhou artillery is much better than relying on Ren Fen, who is somewhat difficult to trust.

"Make you wise! So we will be able to break through Changzhou! Zhang Hao's mood suddenly improved a lot, and he began to drink and laugh with An Renyi and others, looking forward to whether he could ask An Renyi to reward Changzhou as a territory after breaking through Changzhou, so that he would have a real foundation.

"Well, I'm going to be more proactive in attacking the city next, otherwise how can I make a request after the war?" Zhang Hao thought to himself.

……

Not far from here, in the south, there is also a camp, which is much smaller than An Renyi's camp, and their number is only about a thousand people in terms of the number of tents, but compared to An Renyi's camp, which is dominated by infantry, the army in this camp is obviously pure cavalry.

A cavalry team with a total number of thousands of people is still rare in the Jianghuai area, like Li Chengsi, when he went to pacify Shouzhou, the cavalry led by him was only 3,000 Shatuo Jing cavalry, as for the number of cavalry under the command of other generals, the number of cavalry is even less, the few are only hundreds of cavalry, and the number of cavalry with thousands of cavalry in Huainan is only Yang Wu's family except for Li Chengsi!

Yes, this cavalry team is Yang Wu's cavalry. When he ordered the whole army to go south in Sizhou, although Yang Wu tried his best to speed up, the speed of the ships was limited, and it would take at least ten days to reach Changzhou at the current speed.

However, he noticed that some of the ships were light boats, and their speed was much faster than the rest of the ships, and Li Yu's messengers from there for help arrived one after another, making him realize that the situation in Changzhou was not very good, so Yang Wu simply led the cavalry to take the fast boat first, and sure enough, it only took five days to enter the Yangtze River.

Because the number of ships was small, it was conducive to concealment, so they took advantage of the night to cover the spies sent by An Renyi on the bank of the river, and went around to the east of Changzhou before landing.

"Shizi, we have successfully engaged the enemy in concealment now, but every day we wait here for more days, the more likely it is that An Renyi will be discovered, it just happens that there is not much moonlight tonight, should we launch a surprise attack tonight?" Hou Zhan, the cavalry general, asked.

Because they arrived in advance by clipper, they did not bring other infantry except for the 1,000 cavalry, which was more conducive to the mobility of the battle, but also led to a shortage of troops.

Therefore, the most critical part of this operation is to launch a surprise attack, launching a surprise attack before An Renyi knows that they have arrived. And if An Renyi knew about their existence, as long as he sent a part of his troops to contain them, the role of their thousand-man cavalry would be much smaller.

"No need, we have just arrived here, and even if the soldiers can stand it, the horses will certainly not be able to stand it at this time; In addition, An Renyi is also an old fighter, he may not have thought of our existence, but he will definitely consider the possibility of Li Yu going out of the city to attack at night, so our rash night attack may not be successful! ”

Yang Wu shook his head and vetoed Hou Zhan's proposal, in addition to the reason just mentioned, there was another reason that although the lack of moonlight tonight was conducive to a surprise attack, it was also not conducive to the night action of the cavalry. After all, they were new to the area, and they were not familiar with the terrain.

"So let's wait, wait until An Renyi attacks the city during the day and see if there is a chance of a surprise attack! What's more, didn't Li Yu say that Suzhou Xu Wen had already sent an army of 3,000 people to support? Our current strength is still too small, and it is not enough to defeat An Renyi in one fell swoop, so it is best to wait until the reinforcements from Suzhou arrive! ”

The next day, An Renyi's rebels did not come out of the camp to attack the city, and Yang Wu did not think much about it, although it was a little strange. However, on the third day, when thirty Suzhou guns were pushed under the city of Changzhou, Yang Wu couldn't help but be startled.

Now that the reinforcements from Suzhou have not arrived, the defenders of Changzhou are only 3,000 people, can they hold it under the bombardment of Suzhou artillery? Yang Wu couldn't help but worry.

At the beginning, because there were no reinforcements in Suzhou, the Huainan army did not take advantage of the boulder bombardment to attack at the same time so as not to be injured by mistake, but An Renyi will definitely attack at the same time in order to hurry now, so it will be much more difficult to defend the city.

Sure enough, An Renyi sent infantry to attack at the same time as the Suzhou artillery roared, and rushed to the city wall many times in just one morning, and retreated under the desperate counterattack of the defenders, but the situation was also a little precarious, and the city could be breached at any time.

"No, if we go on like this, I'm afraid that the city won't be able to hold out until the Suzhou reinforcements arrive, we must immediately attack, at least destroy these Suzhou cannons!" Yang Wu made a quick decision.
