When the nameless town eliminated the hired Cossack bandits sent by the Stroganov family, Mao Wenlong and Zhang Bingzhong were also thinking about conquering the Omsk fortress, but this fortress was really well built, and the artillery power of the Ming army was still not enough, although it could hit the castle, but it could not form a large breakthrough. There are more people and horses in the Omsk fortress, even if they can break through to some soldiers, they can't form a threat, and there are a lot of artillery in the Omsk fortress, although the power is not as good as the cannon of the Ming army, but under the cover of artillery fire, the Russian army can still defend the fortress.

At this time, Sun Chuanting sent someone to send a large amount of munitions and materials, including a large number of *, and it was also for mortars. Seeing these shells, Mao Wenlong and Zhang Bingzhong were overjoyed, it turned out that the Ming army was equipped with a large number of * so that Mao Wenlong made a great bargain, this guy likes this kind of big killing weapon very much, but these things are better used to defend positions or cities, and they are not enough for siege, in case the enemy comes to a fire attack, it will burn itself if it is not good. With these mortars*, there is no need to be so troublesome, flexible and easy-to-move mortars are a sharp weapon on the battlefield, and it can be said that it is very convenient to use them to maneuver against the artillery of the defending city.

In order to give better play to the effect of *, Mao Wenlong and Zhang Bingzhong discussed and decided to carry out a more realistic feint attack, so that the artillery targets of the Omsk fortress were exposed, of course, this may cause some casualties. In order to reduce casualties as much as possible, the soldiers have taken certain precautions, such as helmets, cuirasses, leg guards and other armor, but if the unlucky guy is hit directly on the head by a solid bullet, there is nothing to say.

Pull out all the cannons, except for the north is a hill, there is no way to place troops, the other three sides are arranged artillery positions, in order to prevent the Russian army from counterattacking, even the baby-like * are arranged to the front of the position, taking advantage of the short darkness before dawn, Mao Wenlong and Zhang Bingzhong quickly arranged the troops in place.

When it was dark, General Petrov of the Omsk fortress finally discovered the arrangement of the Ming army, and he judged that the Ming army might be about to carry out a large-scale siege, in addition to arranging most of the soldiers to strengthen the city wall, he also organized a small number of soldiers to prepare to take advantage of the Ming army's unpreparedness, attack the Ming army's artillery position, and try to find a way to defeat the Ming army.

The artillery of the Ming army began to suppress the attack, and the soldiers rushed towards the city wall, but they all knew that this attack was just a feint, and the ultimate goal was just to let the Tsarist army expose the position of the artillery defending the city, so they were all careful at the time, just to make a show, and when the artillery of the Tsarist army began to fire, the Ming soldiers scattered the team, so that the artillery lost important targets, and had to increase the number of uses.

In the morning, there were more than a dozen attacks in a row, and the most recent one the soldiers almost rushed under the city wall, so that Admiral Petrov was almost about to counterattack, but the Ming soldiers retreated back, and did not give Admiral Petrov a chance to go out of the city, so that Admiral Petrov felt that the Ming army seemed to have some conspiracy, in fact, he really guessed a little right, the Ming army was really unwilling to let him out of the city, and tried to avoid them from attacking the artillery position.

Behind the artillery positions of the Ming army, there were a large number of Ming scouts carefully observing the Omsk fortress in the telescope, and they carefully recorded the location of the artillery positions in the Omsk fortress. In short, all possible artillery positions were recorded as much as possible, and all necessary preparations were made for the next siege.

The battle lasted all morning, the purpose of the Ming army has been basically achieved, Mao Wenlong and Zhang Bingzhong they retreated without danger, checked the casualties of the troops, not bad, the unlucky people who were killed by the shells were less than 100 people, but the wounded soldiers were thousands of people, and after arranging the treatment of the soldiers, they quickly returned to the war room and began to study the next siege plan.

According to the drawings of the scout doors where the shelling was observed, the staff team, after thorough research, finally determined the artillery positions that could be found, and then divided the mortars into several teams. At this time, Mao Wenlong suddenly asked if there were mortars arranged on the north side of the fortress, and the staff officers said no, so Mao Wenlong asked them to arrange ten mortars on the hillside north of the city, and the target was the area twenty zhang away from the city gate, and then said nothing.

The fortress of Omsk, which had been fighting fiercely all morning, was calm in the afternoon, and the Ming army no longer attacked the city, and they were happy to rest, but General Petrov did not dare to rest, he called a meeting of his subordinates to study what was the real intention of the Ming army to attack the city? Why are there some anticlimactic snakes, and what conspiracy is hidden?

In the middle of the night, a group of Ming mortar units set out, in front of them were the infantry responsible for protection, and in front of them were the scouts who had been deployed long ago, these scouts had been secretly scouting around the Tomsk fortress since the end of the battle, they did not dare to be careless, the secret sentry was placed near the city gate, and without any incident, all the troops entered the predetermined position safely.

From the first mortar sound from the south gate, artillery began to fire on the east and west sides of the Omsk fortress, and the dense * Omsk fortress turned into a sea of fire, especially in the calculated artillery position, which was the focus of the shelling. The Omsk fortress was in chaos, but it was a burning fire, especially the artillery positions that the mortars focused on, which would cause explosions from time to time, and later it was almost impossible to tell whether it was the fire caused by the * or the fire caused by the explosion.

After shelling for half an hour, suddenly the artillery team on the mountainside north of the Omsk fortress opened fire, because the distance was a little farther, and when the first shell landed, there were two shells flying in mid-air. But when the first round of shells landed, the soldiers who were observing in the telescope found that the first wave of shells worked surprisingly well, and the fire they saw was several times better than the normal effect, and they immediately understood that this had happened, and after a quarter of an hour, the artillery team completed the entire firing mission. Looking at the northern half of the Tomsk fortress, the fire caused by the shelling is much higher than the fire on the other three sides, and the soldiers admire Mao Wenlong's accurate judgment even more from the bottom of their hearts.

Admiral Petrov did discover the Ming army's intentions, and when he called a meeting of his subordinates, he told them his thoughts, so that they could prepare for a night attack by the Ming army, the Tsarist army was different from the Ming army, and most people in this era had different degrees of night blindness, and they had no good way to do the night action of the Ming army, so they could only defend passively. In order to prevent accidents, Admiral Petrov asked the soldiers to store as much ammunition as possible in warehouses, even if they were not used up during the day's fighting. In addition, part of the artillery was transported to the north of the Omsk fortress, if the Ming army occupied the south side, it could also resist here, after all, the north side is a hill, and it is inconvenient for the Ming army to attack here, such as infantry artillery, cannons, these things are difficult to transport over, without these siege heavy weapons, it is difficult to blow up the city gate.

But the only thing that Admiral Petrov did not expect was that the Ming army would have so many * in this period, he thought of the tactic of attacking with fire, which was a very frequent means in ancient warfare, but it was very difficult to use this method in a well-defended city, it was impossible to enter the city, it was impossible to set fire to it from a distance, and there was no way to use bows and arrows from a distance. This is the way to consider the difference in the generation of weapons, Admiral Petrov did not think that the Ming army would fire with mortars*, and the tragedy happened, even if he predicted it, there was no way to defend it, so he could only passively go everywhere to put out fires, and in the chaotic night, this efficiency was pitiful, and the soldiers died countless times.
