These dozens of large ships loaded with sand and gravel blocked the two tributaries, and the Dongwu Navy never had a chance to enter the main trunk of the Ganjiang River for a while to rescue Nanchang. If they force their way in, the medium- and large-sized warships of the Soochow Navy will run aground at the bottom of the reef.

In order to get through these two rivers, it is necessary to clean up the wrecks at the bottom of the river, which is not an easy task in this era, and must be a time-consuming and labor-intensive task. The point is that the Shu army will definitely not give them time to salvage the sunken ship.

In fact, the third wave of the Shu army's attack was approaching in a blink of an eye, and Huang Xu ordered craftsmen to dismantle part of the stone thrower under Nanchang City and pull the accessories along the river bank in a horse-drawn cart. In addition, the Huang Xujun is also equipped with four guns ~ cannons, although it is a less powerful copper cannon, but there is no problem at all with 400 meters.

These four copper cannons are four of the ten copper cannons that Liu Hou carried back then, all the way from Nanzhong to Lingnan, Liu Hou now has a light and powerful Keqiu kill, naturally he doesn't look down on these bulky things, so he eliminated them.

Although Liu Hou couldn't look down on these eliminated bronze cannons, other troops scrambled to get them, and finally Huang Xu grabbed four guns, Guan Suo also grabbed four, and the remaining two were taken to Jingzhou by Zhang Bai to assist Guan Gong in defending the city.

These four fire~ cannons were divided into two groups by Huang Xu, two guns in each group, and together with those stone throwers, they were pulled by horse-drawn carts along the river bank in a hurry. Soon, they found their target, which was the fleet of the Soochow navy that had fled into the two tributaries.

After two rounds of mine attacks, they lost a total of half of their personnel and ships, and many of the rest were wounded, which almost crippled the Soochow Navy, which had traveled thousands of miles to do reinforcements.

After escaping into the tributary, in the left tributary where Xu Sheng was, it was not easy to gather the army and dock at a harbor to rest temporarily. The Soochow naval army in the right tributary lost its command center and failed to find a general who could serve the people to take charge of the task for a while, and it was not until dawn the next day that the fleet was closed.

Even so, this part of the naval army could not achieve the unity of orders, but they were barely able to get together, and they also stopped at a wide river to rest temporarily. As for where to go, they are still confused.

The Eastern Wu naval army on the left tributary did not escape so far because they closed early, and they were caught up by the Shu army on the shore in the evening. The Shu army that caught up immediately began to set up trebuchets on the shore, and the two guns ~ guns didn't need to be placed, they had their own gun mounts, and the gun carriages had wheels, which were pulled by carriages and ran over.

After arriving, as long as the muzzle of the gun was turned around, aimed at the Soochow ship on the other side of the river, and then the artillery ranged, aimed, and loaded, and the preparations for firing were completed in less than a quarter of an hour.

However, the installation of the stone throwers is not so easy, and they can only continue to wait. During this waiting time, the Soochow fleet first couldn't hold its breath, and sent some speedboats carrying soldiers to rush over, wanting to land on the beach and go ashore to fight with these obviously ill-intentioned Shu troops.

The Shu army had already been prepared, countless fire~ guns were raised, crackling a volley, countless Dongwu sailors were shot, and many people were even driven by the repulsion force after being shot, and fell into the river. The Dongwu naval army, which had long been frightened, saw that it was encountering those terrifying fires ~ spearmen again, and their morale was completely lost, so they turned the bow of the ship and ran.

After entering the firing range, where is it so easy to go, the Shu army quickly disemboweled, loaded, aimed, and fired, and after two rounds of salvos, the Dongwu naval army finally escaped from the range of the Shu army after throwing down hundreds of corpses. After this attack of stealing chickens and rice, Xu Sheng did not dare to send troops to attack rashly, and instead used long-range firepower to attack the Shu army.

Among the large warships of the Eastern Wu Navy, they were equipped with bed crossbows, and even a few had trebuchets, and seeing the failure of the soldiers sent out to rush to the beach and land, these long-range firepower began to rage, bombarding the Shu army on the shore. Because this is a tributary, the river is not very wide, and it is still possible to get bed crossbows and trebuchets with a range of more than 400 paces.

However, at this time, several trebuchets of the Shu army had already been assembled, and they and the two fire ~ guns began to return fire. At this time, the sky had already darkened, and the distance was far away, and the accuracy of both sides was ridiculously different, so that it was better to attack each other than to scare each other.

For the sake of safety, the other soldiers of the Shu army had retreated to a safe distance, leaving only the craftsmen who installed the trebuchets, the soldiers who operated the trebuchets, and the artillerymen working against the enemy's arrows.

In order to see whether these stones hit or not in the dark, the Shu soldiers tied lit firewood and grass to the stones, so that these large stones became fireballs, and their landing points could be seen clearly.

However, this also exposed their location, so that these stone throwers were taken care of. In the end, this trick also lost its effect, because the ships on the opposite shore were all extinguished, and the area was hidden in the dark, and before the Dongwu naval army turned off the fire, the Shu army saw that many ships had already started, and it was obvious that they planned to move their positions to avoid the long-range fire of the Shu army.

The two sides fired several rounds at each other, with casualties on each other, and gradually, the offensive of the Eastern Wu army subsided, and the Shu army knew that the Eastern Wu fleet had moved away, and completely lost its target in the night, so it had to stop the attack.

This night, the Shu army spent the night safely in the guard, and at dawn the next day, they found that the Soochow fleet had long since disappeared, so they continued to disassemble the trebuchet, and then chased downstream.

On the other tributary, the Shu army did not catch up with the leaderless Dongwu fleet for the first time until noon the next day. Because the dragons were leaderless, this detachment did not organize a decent resistance, and when the Shu army began to attack, many ships scrambled to flee downstream.

So, this Shu army also continued to chase downstream, and in this way, the two Shu armies chased the two parts of the Eastern Wu naval army on the two tributaries, stopping and stopping along the way. As long as the Dongwu naval army stopped to rest, the Shu army soon caught up, and then the two sides exchanged long-range fire, and finally, the Eastern Wu naval army was forced to continue to retreat downstream.

It's not that the long-range firepower of the Shu army is so fierce, in fact, most of the time, the long-range firepower of the Dongwu Navy is stronger than that of the Shu army. However, in addition to talking about firepower, there are also many complicated factors such as morale and shape, otherwise, everyone does not have to fight, and the two sides sit down, put their respective military strength on the table, see who is strong and who is weak, and then decide whether to win or lose.

The Eastern Wu army was demoralized by a series of blows, and was pursued like a lost dog along the way, and had no intention of engaging in battle, so every time they were caught up by the Shu army, they continued to flee downstream after a few casual counterattacks.

In this way, the Dongwu Navy on the two tributaries was chased and driven away by the Shu Army on the shore all the way, and the Shu Army on the two roads was like two naughty boys, picking up stones and beating dogs all the way, and finally drove the Dongwu Navy into Poyang Lake.
