With the support of Liuhai artillery, the national army successfully conquered Lichuan and advanced to the southwest of Lichuan. Liu Hai was ordered to support the national army with twenty cannons. On the way, while checking the situation of each gun, Liu Hai constantly sent people out to observe the terrain and measure the distance to achieve the accuracy of the landmark! Such preparations were very effective, and soon the attacking national army was stubbornly blocked by the other side, and Liu Hai was ordered to provide artillery support for the national army's attack! In order to attack accurately, Liu Hai still adopted the last method, using ten guns to advance to the offensive position and shoot directly, while the rest was used to cover his position and cut off his supply and retreat! Advance observation and accurate measurement made Liu Hai's cannon like an eye, and accurately hit the Red Army's position one by one! But the strange thing is that the national army failed to attack six times, lost a company of troops, and gained nothing! After hearing the news, Liu Hai was very puzzled, logically speaking, such a bombardment, coupled with the high-density attack of the national army, should have been unable to withstand the firepower and strength of the Red Army a long time ago!

Bangs first handed over to Wu Fat Man to observe, but this Wu Fat Man didn't find anything, and it was recommended to continue bombarding! But Liu Hai knew that there must be a reason for this, so he personally went to the observation point and looked at the Red Army position with a telescope. At this look, the bangs can see a little way. The deployment of the Red Army is not strict, or it uses straggler tactics, putting a few people every few tens of meters on the position, once the Nationalist Army attacks, it uses a large number of * to stop and kill the soldiers of the Nationalist Army, and although its own artillery fire is very accurate, the effect is not good, the reason is that the Red Army's straggler tactics! Knowing this situation, Liu Hai thought of a way to use binoculars to observe the enemy's firepower concentration points when attacking, and use artillery to carry out close-range support and direct shooting when the national soldiers entered the bomb throwing distance. Bangs, having made up his mind, ran to the offensive position and demanded that the artillery be moved forward, moving down the slope at two hundred meters from the Red Army units! Those veterans told Liu Hai that the distance was too close, and if the other party launched a counterattack, it would not even be time to run! Liu Hai told them that the Red Army would not attack, because they did not have many people in the first place!

Liu Hai is not wrong, there are indeed not many people in the Red Army, but Liu Hai forgot one thing, that is, the range of the gun, the distance of two hundred meters, not to mention the machine gun, even the old sleeve can hit this distance, so after the cannon was pushed up again, it was immediately attacked by the fire of the Red Army! Fortunately, the covering fire of the national army began to unfold, and the shield of the cannon was very wide, so there were not too many casualties, but even so, five gunners were killed. However, after the cannon is closer, the observation effect is super good, coupled with the technology of these old artillerymen, the cannon is almost useless, and every time the cannon is fired, it can destroy a projection point of the Red Army. With the support of ten guns, the offensive of the Nationalist army went much smoother, and after three consecutive attacks, the Nationalist army captured the first line of defense of the Red Army! When it came to the second line of defense, Liu Hai's cannon could no longer follow up with the team to cover the shooting, and could only carry out artillery support from a long distance! Liu Hai personally went to see the positions of the Red Army and found that there were many strong fortresses on this line of defense! This incident makes Liu Hai very strange, because these fortresses are useless at all, they can all be killed with one cover and one round of point shooting, why did the Red Army do this, when they suppressed * before, they were all invisible and intangible, how did they change such a stupid tactic this time!

Bang Hai returned to his artillery position, calculated the correct elevation angle according to the firing table and the distance he had determined, and then ordered each gun to correct the elevation angle, and then fired five rapid shots! Five-round rapid fire is a tactic of artillery, which fires a large number of shells at the fastest speed in a short period of time, mainly used to suppress the attacking enemy army or the opponent's dense target! Bangs saw that the opponent's fortress was very dense, so he used this tactic to cover the blow! I hope to destroy as many other fortresses as possible! As a result, the bangs were correct, the fortresses of the Red Army were simply vulnerable in the face of artillery, and one by one the artillery was removed! Seeing that his artillery fire had taken effect, Liu Hai raised the elevation angle by two degrees and gave the order to open fire. After Liu Hai looked at the destruction of the fortress, he knew that the personnel inside would inevitably retreat, and the distance would probably not exceed two hundred meters, so after destroying the opponent's fortress, he began to bombard its retreat. Liu Hai watched as one shell after another exploded in a crowd of ragged Red Army, and the second line of defense of the Red Army was broken! The commander of the offensive unit of the national army was a division commander, and seeing that the artillery fire was so sharp, he immediately ordered the troops to pursue! Looking at the rushing national army and the bombed embarrassed*, the bangs feel very good! After this battle, the offensive of the national army stopped, because the other divisions did not attack effectively and could not advance effectively, so Liu Hai's unit could not rush on its own!

However, the strong support of Liu Hai and the accurate artillery attack made a good impression on the attacking troops, and the commander of the attacking force asked Liu Hai to advance with the army with artillery, but was refused, because Liu Hai was urgently transferred to Saltpeter, where there was a division* preparing for the attack! Liu Hai hurriedly led his ten cannons to Saltpeter, and the combat mission to Saltpeter was to resolutely resist the attack of the * and retreat its advance attack! Knowing the essentials of the task, he hurried to the saltpeter. After arriving at the saltpeter, Liu Hai found that the national army here had built strong fortresses and deep fortifications and trenches, as far as * was concerned, it was not too easy to conquer such an area! Liu Hai carefully observed the saltpeter terrain, the fortress of the national army was built very strong, and the trenches were also very solid, in this case, the main task of the artillery should be to set up fire blockades, arrange fire coverage, and prevent it from forming a formation or launching an attack on our position in a planned way! Liu Haiming ordered his artillery position to be set up on the left side of the position, because it was the most vulnerable place, and the right side was not suitable for attacking! Bangs gave full play to the firepower of his ten guns, divided into three layers of blocking, and set the blocking line with a distance that was not used! It had just been arranged, and before the bangs had had time to catch their breath, the offensive of the Red Army began!

Liu Hai looked at the * attacking from the offensive position with a telescope, and when the first line of blocking line was reached, five guns fired a salvo, and in a short time several shells hit one place, and the dense explosion blew up the formation of the Red Army, and the remaining five guns began shelling on the second blocking line, and the same rapid fire killed a large number of Red Army troops who rushed through the first line of blocking line on the second blocking line! After firing the five guns of the first line of blockade, the fire was quickly transferred to the third line of blockade, so that the Red Army's attack was already routed on the way of the impact. When the remnants of the Red Army finally rushed to the front of the position, they had to face the double fire of the trenches and fortresses, and one or two out of ten Red Army soldiers who basically rushed up could return alive. Even so, Liu Hai found that the fierceness of his attack and the strength of his will to fight, objectively speaking, far surpassed the national army fighting against him. Liu Hai looked at the pile after pile of bombed broken corpses and the blood that had flowed into a river on the way to the charge, and felt uncomfortable for a while. The Red Army's attack went on for several days, and although it was said that the losses were heavy, the impact was still terrifying, and the only thing I was thankful for was that those strong trenches and fortresses were able to hold back the Red Army's attack! The Red Army's offensive lasted for more than a month, Liu Hai was a little strange, why these Red Army soldiers were so desperate to rush into the fortresses and trenches, this month their own artillery team turned to several places, I don't know how many * killed, and the * offensive did not seem to make any progress, their troops suffered a lot of casualties!

In the battle for more than a month, Liu Hai has completely seen what is called a mountain of corpses and a sea of blood, what is a succession, especially those who know that they can't rush forward with the courage to rush forward, I really admire and shock! Bangs didn't have much time to lament the cruelty of the war, because he was still busy with repairs and maintenance of his cannons! Although the Fourth Artillery Regiment is an elite regiment, not everyone knows how to disassemble and repair artillery, so in addition to those who can't, Liu Hai and some people who know how to start the maintenance of artillery, and at this time, the first stage of suppressing bandits in Jiangxi has ended!
