What to do, the difficult choice rose in Wu Jian's heart, at this time, if he led the troops to retreat, three or four hundred subordinates might be able to retreat most of their bodies, or even retreat into the tunnel, with the help of a solid tunnel, they can also save most of the living force, which is a better choice for Jingui's special forces.

Just gave up the strategic task, although it was force majeure, but as long as he entered the tunnel, Wu Jian only had the theoretical ability to counterattack, from the underground to the ground, even if there was a surprise in the tunnel, it also needed enough personnel, if there were not enough personnel, the counterattack would be carried out unless the other party was not prepared.

With the people on hand in Wu Jian's hands now, even if all the people are restored, it is only 300 people, and the defense line of the buying and selling city, which has caused heavy losses to the Russian army, as long as the Russian army enters the trading city, it will definitely be thoroughly searched, and even a certain amount of heavy troops will be stationed, in this case, there is only one chance, and even the longer the time, the more time the Russian army will be stationed, and the possibility of exposure will be greater.

As long as the surface is withdrawn, this means that the buying and selling city will really be thrown into the hands of the opponent, when the follow-up Russian army arrives, relying on the buying and selling city, forming a line of defense, it is definitely not a good news for the Mongolian war situation, the Russian army, which occupies an absolute advantage in numbers, can be calmly arranged as needed, and Baotou, can only be passively beaten, this is completely two strategic situations, the overall plan formulated before, there is a possibility of bankruptcy.

After several months of hard work, Baotou has integrated the strength of the three provinces, with the help of hundreds of millions of people, if you want to expand the military strength, you can expand the military strength several times, Baotou has its own weapons production plant, weapons will not be subject to external restrictions, but the combat effectiveness of these armies, it is not guaranteed, I have seen two divisions of the Russian army, really with the Chinese army, and even Beiyang is not the same, in the loss of 70, the Russian army, which lost the initiative on the battlefield, still did not completely collapse, held Kyakhta, this, It is enough to praise, if it was replaced by the Beiyang Army, it would have flown a long time ago, and as for the ** party, it is even more useless, except for the three divisions that resisted Beiyang, the strength of the other ** parties is almost all scum.

Wu Jian stared at the battle map in front of him, trying to find a solution from the middle, and then give him some people, not to mention more, three or five hundred people, he could take advantage of the 12 gunboats before they had a firm foothold, and rushed, but now, he could only watch dryly, watching these gunboats swaggering, along the Selenga River, all the way towards Kyakhta.

Time passed slowly, the brightly lit fleet, when there were still five kilometers away from Baotou, suddenly stopped, flat-bottomed sand boats began to dock along the coast of Kyakhta, there was no wharf, but they were not loaded with any goods, it was a well-trained soldier, jumped directly from the boat into the shallow water area, and then rushed to the shore to assemble, in the process of 12 gunboats, began to face the trading city, opened their guns, obviously, is ready to fight.

Oops, Wu Jian was shocked, and then quickly ordered that many positions on the front line should be withdrawn on their own initiative, at least the barricades will definitely not be there, and some houses that are covered by artillery fire will also be partially withdrawn and hide in relatively safe anti-artillery holes.

THE POWER OF THE 120 GUN IS NOT COMPARABLE TO THAT OF THE 75 GUN, THE CALIBER IS ABOUT 50MM LARGER, BUT THE WEIGHT AND CHARGE OF THE SHELL ARE SEVERAL TIMES THAT OF THE 75 GUN, AND THE ABILITY TO ATTACK THE FORTIFICATION IS ALSO EXTREMELY STRONG.

At this time, every remaining strength in the trading city is precious, even if it is Liang Lingdong's armed personnel, a day or two of fierce battles, let them transform from a semi-militarized personnel into real warriors, which is a combat power that can be handled. The radio waves passed through the trading city, one step faster than the artillery fire covered, and before the personnel could completely retreat, the gunboats set up an attack formation and began to bombard the trading city.

The launch of gunboats is much faster than that of the army, Russia has also reached the third navy in the world, and it was once a powerful naval power with dozens of battleships, even if the Russo-Japanese War was a mess and lost most of the navy, but the tradition of their own country made their river fleet quite powerful, from turning to forming a camp, and then to firing artillery, like a cloud of peers, well-trained table xiàn, bringing strong combat effectiveness.

Even if there is no teaching of shooting, even if it is an unfamiliar environment, just by virtue of visual inspection, the artillery fire also fell to the front of the trading city, 120 mm shells, with abundant kinetic energy, crashed into the room at the front position, the thumb-thick steel mesh made of steel bars, plus high-grade cement, is enough to withstand the covering bombardment of the 75 guns, but in front of the 120 guns, a little weak, the first layer of defense was broken through instantly, a big hole appeared, and exploded inside.

As the fortification of the front part of the breakthrough, of course, there will not be only one wall, after the space inside has been rationally used, it is not all filled with cement, but filled with some filling materials, which are broken through and produce debris, but successfully reduce the kinetic energy of the shells, almost in front of the second wall, 120 shells have lost most of their kinetic energy, and do not have the ability to kill.

Because they were reminded, most of the soldiers left the weak observation post that was easy to be attacked by the 120 cannons, and only a few hidden points remained, including Wu Jian's headquarters, which was specially designed and blocked all around, and it was difficult for ordinary ballistics to hit here, so Wu Jian was able to follow the command here.

A total of 25 waves, 300 120MM shells attack, can be much more powerful than before, tens of thousands of 75 artillery attacks, plus the range of the attack is relatively concentrated, the front part, close to the river of the small courtyard, withstand the largest number of artillery fire, three or four rooms were collapsed, fire points were also destroyed, unusable.

With a sigh, Wu Jian knew that he had to make a choice, the defense line of the trading city, after all, was not a real military fortress, and it could already be regarded as an extraordinary performance against 75 guns, and against 120, as long as the number was sufficient, the protection system on the ground would be cleared one by one under the case of artillery fire, as long as the other party had enough shells. Being beaten passively will not only fail to gain the initiative on the battlefield, but will even fill everyone into it, how to do it.

This decision is extremely painful, especially for the special forces who regard himself as the king of soldiers, Wu Jian feels that this may be a stain on his life, and because of this, even if he has made a judgment in his heart, a certain voice is still saying to him, wait.

After 25 rounds of artillery coverage, the gunboats did not continue, I don't know if there was no result, or they were not ready to waste any more shells, in short, after they fired a round of artillery fire, they guarded the side of the sand boats, 11 sand boats, unloaded in the absence of ports and docks, the whole operation took 2 hours, when the personnel came down, quickly rushed to Kyakhta, and the gunboats were cruising on the water, did not fight again, but from time to time swept the surroundings with machine guns.

The other party's calmness made it difficult for Wu Jian to decide, it was already dawn, Wu Jian was about to send a telegram to the Baotou base camp, asking what should be done at this time, at this time, the correspondent took a telegram, came with great surprise, and did not wait for Wu Jian to ask, he said loudly: "Battalion commander, good news, we received a point-to-point radio signal, and a battalion came to support us!" ”

Point-to-point, this is the contact method of the radio station, most of the radio stations, because of the relationship between the distance, must be amplified through the guò signal tower, to be able to accept, of course, not without exception, in order to command and communication convenience of the special forces, in the special forces of wireless telegraphy, there is a special reception and transmitter, so that two stations, without the amplification of the signal tower, can be directly contacted, but such a limit is also very large, do not exceed 25 kilometers, otherwise the long wave will be attenuated to the point that it cannot be received.

This is a chicken rib for long-distance telegraphy and control, but for special combat forces, which are often interspersed and infiltrated, it is extremely effective, this kind of radio is about 3 kilograms heavier than ordinary radio stations, which may be a difficult problem for ordinary troops, and for special forces, it is easy to match them all.

"First battalion, how many people are here?"

"700 people!"

Wu Jian's eyes lit up suddenly, just like a clear spring found in the sand mold, 700 people are already most of the military strength of the first battalion of the special forces, different from the reserve of the second battalion, the first battalion has been in the army for many years, participated in the war against Beiyang, rushed to Mongolia, and even one battalion of its own strength, it ensured that the situation in Mongolia will not deteriorate, whether it is combat effectiveness or combat experience, it is far from being comparable to his second battalion. It's a charcoal in the snow.

Wu Jian said a little anxiously: "Who is here in the first battalion, and where is it now!" ”

"Camp Commander Blue is here personally!" The correspondent said excitedly: "The message has the exclusive signature of Battalion Commander Lan.

"That's great!" Wu Jian thought for a moment and said, "Order, all on alert, by the way, tell Battalion Commander Sù Lan, the situation we are facing!" Wu Jian had already put aside his previous thoughts, and what rose from the depths of his heart was ecstasy, if just now, he really decided to retreat, it would not be a huge mistake, a battalion of reinforcements came up, but they withdrew from their positions, this is a big joke.

Let the correspondent go, but in Wu Jian's heart, there is a question that has been lingering, how did the first battalion come about, the first battalion participated in the battle of Kulun, and he knew that he played well, but the first batch to come was from the first mechanized division, not the first battalion of the special combat team, so it was difficult to put on wings and fly over.
