I fought guerrilla warfare in the Yimeng Mountains during the Anti-Japanese War

Just after dealing with the penicillin problem, Shen Honglie handed over a telegram from the New Fourth Division's Reconnaissance Special Forces. The Japanese army had taken over all the coastal artillery batteries built by the Germans, rebuilt the broken ones, and added two more batteries at Gouyashi and Jinlingshan in the Laoshan Mountains. Gouyashi was a coastal defense battery, and Jinlingshan was a land defense battery. All the batteries were garrisoned.

新四师特战队侦查的非常细致，日军主要使用的岸防炮是三式76.2mm高平两用舰炮、三式140mm舰炮和一0式120mm高平两用舰炮三种火炮，其中又数三式76.2mm高平两用舰炮日本布置的最多。

There are no super large-caliber coastal defense guns as imagined, but the Japanese Type 76.2 9.43mm dual-purpose naval gun can fire 13kg grenades. Its maximum range can reach more than meters, and its rate of fire is faster than the other two types of naval guns, reaching rounds per minute.

In addition, the standard firing rate of the Type 140 6mm naval gun is 10 rounds per minute, the maximum firing rate is 850 rounds per minute, the initial velocity of the gun is meters per second, and the maximum range is meters.

The largest caliber Type 0 120mm dual-purpose naval gun has a maximum range of meters and a maximum firing height of meters. However, the firing rate is only six rounds per minute, which is useless for shooting down airplanes. But Chen Feng has never thought of using a gun to shoot down airplanes. Is the permanent artillery afraid of being bombed by airplanes? That's a joke. As long as it can shoot down the invading Japanese warships, it is completely sufficient.

Chen Feng was now somewhat grateful to Shen Honglie. His mind had never thought about the artillery at all. In the first two surprise attacks on Qingdao and the Qingdao airport, the Japanese army did not make use of the artillery at all, otherwise there would have been heavy losses at that time.

As expected, professional matters should be left to professionals. If the special forces of the Yimeng guerrillas were asked to conduct reconnaissance, the most they could do was to find out which artillery position had how many guns and what their calibers were. It would definitely not be so detailed and had nothing to do with reconnaissance capabilities. What was important was knowledge and technical issues.

In the back seat of the jeep, Chen Feng felt a little touched when he saw Shen Honglie driving seriously. No wonder the New Fourth Division did not recruit civilians, but was very enthusiastic about the Imperial Army, which he looked down upon. He relied on having a suitable training outline, which was something that came seventy or eighty years later. Shen Honglie did not have it. He understood better the time and energy required to draw a blank sheet of paper.

"Captain, I always feel there is some conspiracy when you stare at the back of Commander Shen's head like this."

"Zi Han, don't talk nonsense. I just admire Brother Shen. His Marines have a very high level of skills and tactics. The closer we get to the sea, the more we can see their excellence. It's not easy! It's worth learning from."

Seeing that Shen Honglie was concentrating on driving and not paying attention, Song Zihan asked secretly:

"Captain, are you planning to form a navy? Are you planning to seize the Japanese warships?"

Chen Feng stared at Song Zihan closely. Song Zihan looked back at him without showing any weakness. Seeing the inexplicable emotion in Chen Feng's eyes, he finally lowered his head.

"Captain, don't doubt me. I'm just guessing. When we formed the Jiaolong Regiment, we had the experience of capturing the Kitakami cruiser. I guess this time you might be planning to attack the Japanese warships on the coast of Qingdao."

Song Zihan was afraid that the captain would think she was asking questions for no reason and would be angry. In fact, Chen Feng was looking at her with emotion. Chongqing could send someone here with confidence, so there must be something more complicated than it seemed. She understood her strategic purpose with a simple deduction. Her little brain was as smart as Li Yunyan's.

"I didn't doubt you. If I didn't trust you, I wouldn't have let you stay. I'm just surprised."

Song Zihan immediately became active again after hearing that, and looked at Chen Feng with a gossipy look on her face.

"Captain, I've discovered what kind of magic potion you gave Sister Yunyan. Ever since you guys started snatching oranges at the cave entrance, she has been obviously much happier these days. Do you have any more of that magic potion? I want some too."

"Stop talking nonsense, we are fighting and marching."

"Hmph! Let's talk about it after the war."

At one o'clock in the morning on September 9, the convoy led by Chen Feng and Shen Honglie arrived at Zhushan. They were silent all the way and hid after arriving at Zhushan. They launched the general attack at night. All the heavy firepower was here. They must not let the Japanese army discover them, otherwise the bombers from the newly renovated Liuting Airport would flatten this place with one takeoff and landing.

The city of Qingdao was still calm on the surface, but a storm was brewing. The Japanese army seemed to have discovered nothing, and neither the airport nor important institutions had strengthened their defenses.

In fact, the Japanese army had considered the possibility of the Yimeng guerrillas taking action, analyzed the Jinpu Line and the Longhai East Line, and also analyzed the cities of Jinan and Qingdao. In the end, they all agreed that there would definitely be cold gun actions, and the direction of the actions would definitely be the two railway lines, especially the middle section of the Jinpu Line, which was related to the transportation of materials. If it was blown up, it would definitely have some impact on the Zaoyi Campaign.

When the Lunan Detachment joined the confrontation on the Jinpu Line and the Longhai East Line, the Japanese high-ranking officers became more confident in their own judgment. Two telegrams were sent to Xuzhou and Lianyungang, ordering all garrison troops to defend the city with all their might. From today on, they had to sleep with their eyes open and load their guns even when squatting in the toilet.

In the morning, Chen Feng and Shen Honglie separated, and all command organizations also dispersed and hid. If nothing goes wrong during the day today, Qingdao City will be stable.

Dadingzi Mountain is located on the west side of Jiaozhou Bay. Standing on the top of the mountain, you can completely overlook Jiaozhou Bay. At the northern foot of Dadingzi Mountain, there is a village called Niuqiqian with dozens of households. Two households in the village are far away from the center of the village and are close to the foot of Niuqi Mountain.

These two families were the homes of two soldiers from the special operations platoon of the first company, second battalion, third regiment, third division, of the New Fourth Division. They set up their command post here, and also set up two large-caliber machine guns on Niuqi Mountain. The Japanese army would not be able to affect them at all unless there was a large-scale air raid.

In the west yard, Song Zihan and the communications team have set up the radio station. The Special Operations Battalion and the Jiaolong Regiment have all gone in and will report any progress at any time. Chen Feng must ensure that he receives the news and issues orders as soon as possible.

Song Xiaoniu completely lost the laziness and mischief she had on the road, and immediately entered work mode, directing a squad of communications soldiers to monitor different bands, and she herself also wore headphones to monitor the special band of the Jiaolong Regiment.

Within the morning, all the special operations battalions had replied and had assembled at the designated location, ready to strike the predetermined targets at any time.

At three o'clock in the afternoon, the Jiaolong Regiment finally got news that a Japanese light cruiser, the Yura, appeared in the open sea and was cruising in circles, about ten kilometers from the coast of Qingdao. A destroyer, the Den, was parked at the dock. The officers and soldiers on the ship seemed to have some problems and were queuing up to go to the Army Academy for a physical examination, which might be a routine physical examination.

Wang Dalei judged that the Japanese cruisers would most likely dock at night. As long as they entered the port, they would have a chance. Otherwise, they could only blow up the artillery batteries built in various places.
