Grenade launchers, infantry mortars, and 92-foot cannons fired one after another.
Countless artillery shells landed on every line of defense of the Jiangning Fortress.
Xiao Yan and Yu Xiao Qing were hiding in a fort.
Xiao Yan couldn't help but urge them again as they listened to the cannon fire.
"Or send another telegram. It was already two in the morning. Once the sun rises, we can only jump into the river and escape.”
Yu Xiao Qing was also very helpless,"I have already sent people to send the message many times. The other party said that they would send a fleet over soon. Moreover, our navy sank the last few remaining warships and blocked the river to prevent the Japanese navy from coming over.”
"Really?" That's good."
Xiao Yan had no confidence in Principal Jiang's personality.
It was a gamble.
Another batch of mortar shells, infantry shells, and hand shells came with a sharp and strange sound.
The shrapnel flew past Xiao Yan's head.
Then, there was a short period of silence.
The standard tactic of the Japanese army was the coordination of infantry and artillery.
After a wave of bombardment, the Japanese infantry was about to charge.
The soldiers on the defense line began to shoot desperately against the artillery fire, leaving the Japanese soldiers who rushed up with corpses.
After the Japanese army retreated, another earth-shattering bombardment enveloped them.
The Japanese's artillery fire was really fierce, and the national army was very passive.
This time, the whistling and explosions were much more violent, because they were already the cannons of the A Seeds Regiment.
Gu Shoufu's 6th division had arrived.
Another intense battle ensued.
The enemy's artillery was very tricky.
The cannonballs didn't just explode on the ground. They exploded in the air, delayed, and drilled into the soil. They moved in all kinds of ways on their killing trajectories.
Even if the soldiers of the national army were lying in the trenches, they would still be killed by the artillery fire.
Throughout the night, Xiao Yan saw all kinds of Japanese heavy artillery.
50mm grenade launchers, 70mm infantry cannons, 90mm mortars, 75mm mountain cannons and field cannons, 105mm field cannons and mountain cannons.
There were all kinds of things.
At the same time, the Japanese would also fire flares to allow the bomber planes in the sky to identify the position of the national army and carry out large-scale bombing and killing.
This was also the reason why Xiao Yan hated positional warfare.
If his equipment was inferior, he would be completely suppressed and hammered on the ground.
A well-equipped 6th division was enough to make tens of thousands of soldiers die.
Yu Xiao Qing's casualties continued to increase.
Xiao Yan wanted to fight back like before. It was unrealistic to fight as a guerrilla.
Because there were three Japanese divisions waiting at the foot of the mountain.
If they rushed forward, the Japanese could use their heavy firepower to clear out all the enemies within a few minutes.
Xiao Yan and Yu Xiao Qing could only silently bear the brunt of the Japanese artillery fire.
Xiao Yan couldn't help but urge Yu Xiao Qing.
"Is your principal still not going to make a move?"
Yu Xiao Qing was also anxious,"He will definitely come, I guarantee with my life." If you don't come, I'll chop off my head and give it to you.”
"Why would I want your head?" Xiao Yan smiled bitterly.”
Xiao Yan looked at the corpses of the soldiers lying in the trenches.
At this time, the Japanese stopped.
The calm before the storm.
Xiao Yan took out his binoculars and looked at the situation at the foot of the mountain. His vision was straight into the artillery position on the opposite side.
Xiao Yan's expression changed.
"F * ck you, the Japanese are going to release poison gas bombs. Order the defenders of the first defense line to retreat to the second defense line.”
The defenders of the first defense line quickly retreated.
A few minutes later, the Japanese gas bombs arrived.
Mustard gas spread throughout the entire first defense line.
The Chinese soldiers retreated in time to avoid the poison gas, but the Japanese army captured the first line of defense.
The Japanese artillery moved forward, and the national army became more passive.
Xiao Yan scratched his head and asked Yu Xiaoqing with a bitter smile,""When is your principal coming? If the Japanese advanced a step further, the artillery fire would cover the entire river.”
Yu Xiao Qing was speechless.
At this time, the Japanese army launched their 17th charge, ready to break through the second line of defense.
It had to be said that the 6th division's combat power was truly a headache.
The tens of thousands of soldiers at Jiangning Fortress were beaten up by his regiment.
In just one night, he had charged seventeen times.
This meant that the Japanese were really anxious. They wanted to take down the Jiangning Fortress regardless of the casualties. They wanted to slaughter the soldiers and civilians of the Chinese Empire who had humiliated the Japanese Empire.
Of course, the 6th division was strong and Xiao Yan wasn't to be trifled with.
When he ordered the soldiers at the first line of defense to retreat, he planted mines along the way.
A vanguard unit of the 6th division had just charged up when they stepped on a mine.
Boom! A brigade was blown up by the mines and retreated in panic.
In this pitch-black night, it was not easy to clear the mines.
This gave Xiao Yan a chance to catch his breath.
Xiao Yan began to pray.
If Principal Jiang could send a fleet to rescue him, he would definitely build a shrine for him when he returned and worship him.
At this time, the Japanese artillery fired again.
The 75mm and 105mm shells landed on the ground and were used to clear the mines.
The Japanese infantry, on the other hand, stepped on the mines and charged forward.
He was really tough.
It was a desperate fight.
The Japanese army was also anxious.
At the same time, the Japanese once again fired poison gas bombs.
The poisonous gas bomb fell to the ground, and white smoke rolled out. The smoke spread along the ground like a solid wall of smoke.
"We can't retreat anymore." Xiao Yan gritted his teeth. The second line of defense is the bottom line."
Xiao Yan personally picked up his machine gun to support the second line of defense.
"Be careful of the poisonous gas."
Xiao Yan replied domineeringly,"I'm immune to all poisons. Don't worry." I will guard the second line of defense."
