When Suo'etu first built the barrier, he did not expect that anyone could attack the barrier from one side of the stone wall.He thought that as long as the first barrier was safe, the other barriers would not be attacked from the side.Therefore, he only focused on the enemy's attack from the bottom of the mountain, and completely neglected the defense on the side of the rampart.This is also crooked, retaining a glimmer of hope for Aobai to overcome the barriers.When the first barrier is taken down, there is a path leading to the second barrier on the side of the barrier, which is difficult to walk, but it is much easier than stepping on the cliff wall to attack.However, the Northwest Army also learned the lesson of the first barrier being breached, and began to melt the snow early, freezing all the walls with thick ice armor.From a distance, under the sunshine, all the walls in the canyon halfway up the mountain are shining with dazzling light, which is spectacular.With the defense of ice armor, it would be even more difficult for the artillery of the Qing army under the mountain to collapse the barrier as they had just now.On the contrary, the non-commissioned officers of the Northwest Army, who were hiding in the barrier, could use the cover of the barrier to calmly shoot the Qing army attacking from the flank.As soon as the Qing army crossed the foot of the hill and was exposed to the path, they would be killed by bullets fired from the muzzles of the ramparts.The Qing army could only crawl on the path, slowly advancing while preventing the snow under them from slipping and falling down the mountain.Such an attack was still no better than when the first barrier was attacked, and the Qing army still suffered heavy casualties.The Qing army on the mountain, using the corpses of their dead companions as cover, pushed the dead bodies forward.However, when they approached the barrier to a certain distance, they would throw flower bombs and blow up the mountain with the dead bodies and the living Qing troops.The Qing army crawled forward, and it was useless to throw flower bombs, and they often could not throw them into the barriers.Stand up and throw, not to mention standing up, even if the head is slightly higher and exposed to the muzzle of the opponent's gun, the bullet fired from the opposite side will kill you.The advance army is an elite group selected by the Northwest Military Region, and all of them have outstanding marksmanship and bullets.Let them squat behind the barrier and shoot without any scruples, the Qing army is much easier to hit than the moving targets they hit during their usual training.The flowering bullets of the Qing army were all captured by the other side, and the number was limited, so they could not be wasted by throwing them around, and they could only be beaten as targets.If you want to break through the barrier, you have to count on the cannon under the mountain to knock down the barrier.But the cannon bombardment with a thick ice barrier, and I don't know how much more shells will be consumed, and if I don't have to transport it from Shengjing, I will be blown to the death, and I can't be stopped here, and I won't take back Hetuala.The commander of the North-Western Corps at the general pass also gave the order.This order is not to defend the fortress and the Manchus desperately.As soon as the barrier is blown down, the guards immediately retreat to defend layer by layer, mainly to consume the enemy's strength, but also to preserve their own strength.After all, their own forces are limited, the defensive battle at the first pass is so fierce, and the subsequent battle is afraid to be even more intense, they have to save their troops, and in the future, they will have to guard the old city of Hetuala, no matter how thick the ice above the barrier is, under the bombardment of the cannon at any cost, there will always be a time to be destroyed.As long as the ice is destroyed, the ramparts are not far from collapsing.At this time, the soldiers, under the leadership of the squad leader guarding the barrier, quietly evacuated with all the supplies, including the corpses of their fallen comrades, before the enemy attacked the barrier, and returned to the general pass to assemble and standby.Before the fall of the General Pass, they would retreat to the old city of Hetuara to rest and prepare for the defence of this last fortress.Niu Fangliang asked all regiments to take turns to attack and defend, and they all fought with the Qing army, just to make everyone comfortable, but not to let everyone throw their lives at these passes.It took another hour and a half, with countless casualties, and Ao Bai finally took the second barrier.At this time, it was already getting dark, and the army camped in front of the second barrier, and continued at dawn the next day.The mountain pass was cold and windy, and the Qing army had nothing to protect from the cold, so they could only cut down trees everywhere and light bonfires to keep warm.From a distance, from the pass to the direction of Salhu, bonfires were lit up everywhere, and the red flames were discharged for dozens of miles.And the Northwest sergeant in the fortress on the mountain was lifeless, and there was no spark to see for warmth.Ao Bai wondered, on such a cold day, why didn't these Northwest soldiers light a fire to keep warm, they were not afraid of this cold weather, how could it be that he didn't know that the Northwest Army had eiderdown sleeping bags and kerosene stoves.He quickly had his own explanation.When the barrier was built on the mountain, the trees were cut down, and the dirt and rocks on the gentle slope that was easy to climb were removed.The soldiers were on the rampart, and there was actually no way except for the path leading to the next one.So, they can't go out and find trees to light fires to keep warm.If I launch a sneak attack in the second half of the night, I will definitely be able to eliminate the frozen soldiers in the barrier and quickly occupy the barrier, where does he know, the soldiers in the barrier, in addition to leaving a sentry to monitor them, the rest of the soldiers are in the sleeping bag, and they are sleeping soundly at this time.In the second half of the night, the Qing army took advantage of the reflection of the snow on the ground and secretly launched an attack from the side and down the mountain at the same time.This time, the Qing army thought that the northwest soldiers in the fortress were frozen, and they became bolder, and a large number of soldiers gathered on the path and the cliff wall below the mountain, trying to attack the barrier at once.The soldiers on the side path were one by one, and the cats advanced on their waists.As soon as they approached the place where the barrier was a stone's throw away, flames appeared on all the muzzles of the fortress, and the gunfire rang out suddenly, and the Qing army was killed and wounded.People stand too densely, there is nowhere to hide, often people can kill two or three Qing soldiers with a single shot.The Qing army in front could only stand and be beaten, and there was nowhere to run.There were steep slopes all around, and when I left the path, I quickly slipped and fell down the mountain by the snow on the ground, and if I didn't die, I had to break my head and blood, and break my arms and legs.The Qing army behind was directly frightened stupid, ran around in the dark night, and fell down the mountain again, falling to his death.The Qing army under the mountain was even more miserable, and under and around the barrier, it was deliberately made into a cliff when it was built, in order not to let you climb up.This is good, I was thrown down by a few flowering bombs, and exploded directly in the crowd, only the flesh and blood of the explosion flew sideways, screaming and wailing, and all the bones went down the mountain.In this battle, the Qing army suffered more casualties than those who attacked the fortress during the day.Worship this nest, you said okay, I have nothing to do at night, what mountain Wang Shuo's soldiers are all with Wang Shuo, one by one, there are many tricks, how can he let me take advantage of this, I am not full of food, but he just can't understand, you say that he is on the top of this mountain, the wind is so strong, the weather is so cold, why is he not afraid of freezing, if you don't understand, you can't understand it, anyway, he has to teach a lesson, and the Northwest Army fights, you'd better come step by step, don't be careful, otherwise, the death will be even worse, let's not play hanging, Tomorrow will continue, the artillery bombardment under the mountain, the flank attack on the mountain, and the collapse of the barrier, we will win, but this way of playing, how many people and shells will be filled:
