After the dismissal of the predecessor, the newly appointed Russian intelligence staff officer did not dare to slack off at all, so a piece of information about the retreat of the Chinese troops was placed on Grodeko's desk.

Grogerko thought to himself: "Why does Lin Yuanwei want to withdraw his troops? He had no clue, got up, and paced around the room.

The staff officer saw his thoughts and asked, "General, are you thinking about Lin Yuanwei's withdrawal of troops?" ”

Grogerko nodded, and the staff officer said: "Lin Yuan knew that their troops were insufficient, so they withdrew, and the troops they invested were only more than 10,000 people, while our troops combined were 40,000. ”

Grogerko shook his head lightly and said, "To evaluate Lin Yuan's troops, you can't just look at the number of people. ”

At this moment, the herald ran in and said: "Report to the general, news has come from the fishing port, all the gunboats of the fleet have returned to the port, and now they are waiting for the order, and the infantry from the fishing port has more than 2,000 people on board, ready to enter the battlefield." ”

Grogeco slapped the table excitedly and said, "Order the fleet to go out at once, blow up all their boat bridges to the bottom of the river, and order the troop carriers to send the troops directly to the west bank and block their retreat route!" ”

As soon as the herald left, Grogerko said to the staff officer: "It seems that I am thinking too much, Lin Yuan must have known the news of our fleet's return to Hong Kong, and was worried that his back road would be outflanked, so he ordered the withdrawal of troops, but he wanted to retreat, but it was not so easy!" ”

At this moment, the man sent back by Perov also arrived outside the headquarters, and Grogerko hurriedly let him in, and as soon as the man came in, he said: "The Chinese artillery has all been withdrawn, there is only one malfunctioning gun left, and when they were about to blow it up, we rushed up and drove away the Chinese, and now, the gun is ours." ”

Grogeco asked: "Where is this artillery now?" ”

The soldier replied, "It's too heavy for us to move." ”

"I'll send cavalry over to help you pull it back," said Grogerko. As soon as the soldier left, Grogerko smiled and said: "Great, this mysterious artillery is the most powerful cannon of the Chinese, they don't even have time to destroy it, it seems that they are really in a hurry to retreat!" ”

Grodeco's voice changed with excitement, and he ordered: "Order the 102nd Division of the First Army to immediately pursue the Chinese troops; The 24th Cavalry Brigade detached a unit and went to grab the artillery. ”

The commander of the First Army, who was commanding at the front, Potanin, hurriedly passed on the order, and the 102nd Division had been pressed and beaten by Chinese troops in the previous battle, losing two villages in a row, and when he heard the news of the retreat of the Chinese, he was so excited that a gambler who had lost all his pants caught a good deck of cards and hurriedly chased after Pavlov's village. The Russian army thought that all the Chinese troops in the village had withdrawn, so they swaggered towards the village, who knew that as soon as the road reached the entrance of the village, the Chinese drilled out of the trenches, the muzzle of the gun spat out tongues of fire, the Russian army was caught off guard, was knocked down dozens of dozens and then hid more than 400 meters away.

At this time, it was already more than three o'clock in the morning of October 30, the sky was covered with dark clouds, the visibility was extremely poor, and the Russian army could not figure out how many Chinese troops were outside the village, and they even began to suspect that the Chinese retreat was fake and the ambush was real.

Just when the Russian army was hesitating and in a dilemma, the blocking force in the trench had quietly retreated, and the other blocking force had already built fortifications in the Volga village and was ready to take over the blocking.

Although it was already late at night, Lin Yuan was still in the command headquarters to deal with unexpected situations that might arise at any time, and Zhang Xiaoguang suddenly sent a message: "The Russian army's gunboats and troop carriers are departing from the fishing port and heading towards our landing position. ”

Lin Yuan was shocked when he heard the news, and thought: "The Russians want to copy the back road of the Third Division, once the pontoon bridge built by the troops crossing the river is destroyed, the Third Division will be surrounded on the east bank of the Heilongjiang River. ”

Lin Yuan thought to himself: "Didn't we occupy the Russian army's battery?" It couldn't be better if you hit them with your opponent's cannons! But after thinking about it: "No, our gunners are not familiar with the Russian artillery, and it is dark, if the Russian army cannot be stopped, the third division is in danger of being annihilated." ”

Lin Yuan immediately ordered the Songhua River fleet to go upstream to block the Russian gunboats. Lin Yuan specially instructed Yu Ming: "Remember, your task is to stop the Russian fleet, not destroy them. ”

Yu Mingming knew that Lu Daolin Yuan's order naturally had his reasons, so he did not ask in detail, and immediately led the six gunboats of the Songhua River fleet to sail towards the Russian gunboats, and the Russian army invested all 20 gunboats and 100 troop carriers this time, with gunboats in front and troop transports behind, forming a mighty fleet. With the help of powerful night vision reconnaissance capabilities, Yu Ming discovered the formation of the Russian fleet in advance, and the Russian fleet placed two columns on the river, and the ships between the columns were not parallel, but staggered in pairs, and the one in the back was about 45 degrees below the side of the front one, and the straight-line distance was about 300 meters. Such a formation gave Yu Ming an opportunity to take advantage of it, and Yu Ming arranged the six gunboats in an arc, so that each Russian gunboat formed a huge advantage of six to one; Yu Ming decided to block the attack at the bend of the river, where the river was wide on both sides and narrow in the middle, and several Russian gunboats were sunk, and the ones behind were blocked and could not enter. At about four o'clock in the morning, Yu Ming's fleet arrived at the designated waters, and immediately announced the control of lights, there was no light on all the ships, and in the dark night, it was impossible for Russian gunboats to detect them.

At half past four in the morning, the Russian gunboats came from a distance with their headlights on, and Yu Ming judged according to their lights: The Russian gunboats were still more than a thousand meters away from their formation, so they ordered all ships to prepare for battle.

The ships in the Songhua River fleet were not equipped with radios, and Yu Ming ordered that there should be no lights, so the communication between the ships became a great problem, and the soldiers on the ships thought of a good way, because the distance between the ships was relatively close, so everyone used the method of hitting the water with wooden sticks to transmit information, and different times represented different orders.

When the Russian gunboat sailed into a distance of one thousand meters, Yu Ming ordered the cannon, the 75 mm gun on Yu Ming's ship was the first to fire, the first gun directly hit the gun in the bow of the Russian gunboat, and the violent explosion directly lifted the gun into the air at a height of ten meters, and the other gunboats fired in turn, and the shells hit one after another, however, the shells did not blow up to the part below the waterline, so the ship did not sink.

However, the ship's main cannon was blown up, and it could only be beaten, and could not fight back, so it increased its horsepower and tried to rush closer, but a shell exploded at the base of the chimney, and directly lifted the chimney, without the chimney, the steam engine was greatly reduced, so the speed slowed down.

It was so slow that more shells fell on it, and one shell passed through the deck and exploded in the steam engine room, causing the whole gunboat to lose power and cross the river, and the two gunboats behind saw this and hurriedly accelerated, wanting to overtake their wounded companions and counterattack the Chinese gunboats.

However, as soon as the gunboat behind the Russian army appeared, it was smashed on the body by a series of shells, this time the gunboats used incendiary bombs, and both Russian gunboats were on fire.
