Anti-Japanese blood sacrifice mountains and rivers

[Volume 18] Chapter 142: Chapter 61 Flesh and Flesh Line of Defense (2)

------------

How did the Japanese know that the Germans built the Swallow Rock Castle for experimental purposes and did not calculate any cost input at all, so the concrete structure of the No. The distance between the first and second floors is filled with a large amount of granite, while there is a five-centimeter-thick steel plate between the third and second floors.

It can be said that the cost of such a project itself is huge. The Germans are conducting experiments in China with Chinese money. Because the construction cost of the No. [-] Mother Fortress of the Yanziji Fortress has greatly exceeded the standard, the original [-] blockhouses were reduced to Nine seats.

After more than 20 shells in a row, the No. 1421 Mother Fort has been bombed beyond recognition. The steel bars are exposed in the broken concrete, but the No. [-] Mother Fort, which is embedded in the rock as a whole, still stands tall.Anti-Japanese Blood Sacrifice Mountains and Rivers [-]

The 150-type 150mm cannon equipped by the Japanese army is due to the problem of the gun steel produced in Japan. After the third cannon, the barrel will heat up extremely. If it is fired, it will cause serious wear and tear. The modern reinforced concrete fortress is not old and fragile in Nanjing. Moreover, the life of the barrel of the Type 160 140mm cannon equipped by the Japanese army is only [-] rounds, which is much shorter than the [-] rounds of the Navy's [-]mm naval gun.

Therefore, the Japanese army was forced to stop the bombardment and to cool down the barrel. It can be said that the result of this round of bombardment was very unsatisfactory. After all, this was a Prussian masterpiece built using 120 tons of steel bars and more than 2000 cubic meters of concrete.

Facts have also proved that the German's layered fortress design was quite successful. Later, the Germans built the famous "Wolf's Den" in Austria, using this layered pouring technology to increase the filling.

Yoshika Ryosuke put down the binoculars, looked at the artillery captain Shino Fujino with a helpless expression on his face, and said, "The Germans are famous for their rigor. It's incredible to have such a strong fortress? I'm afraid there are only a few exceptions with the national strength of the Japanese. The fortress here is so strong, and the rest are probably like tofu on the Wu Fu line."

How did Ji Jialiangfu know that the entire Nanjing includes Wulong Mountain, Qixia Mountain, Zijin Mountain, and Jiangjun Mountain fortresses, and only Yanziji has such a strong fortress, but there must be someone to hold on to the strong fortress In history, these fortresses and their heavy artillery and anti-aircraft artillery were captured by the Japanese without bloodshed.

The Japanese wanted to dismantle the fort, only to discover the secret of its construction, so when the Japanese built a large-scale defense line in the Northeast in 1939, many of the main support points used this technology.

After Nagumo Tadaichi was seriously injured and killed, the Imperial Japanese Navy was furious. The special team that attacked Yanziji this time was eight light cruisers and destroyers led by the armored cruiser Yaeyama under the command of Rear Admiral Mataro Tanimoto, commander of the No.11 team. A special fire strike formation formed.

When the Yaeyama appeared on the Yanziji River, the aerial bombardment and land shelling had just ended, and Mataro Tanimoto of the special strike formation immediately ordered to use the flagship Yaeyama's main shell impact as a correction to bombard Yanziji.

In the artillery fire fired by the fleet, Yanziji was once again submerged by artillery fire. Yoshika Ryosuke looked at his watch. The naval formation arrived at the scheduled river to bombard Yanziji four or ten minutes later than the scheduled time.

In a military operation where the time is accurate to the minute, two or three minutes late is fatal, let alone four ten minutes late, and the naval special formation immediately started shelling after arriving, without even contacting the army. Make contact, if Yoshika Ryosuke ordered the troops to attack just now, then the artillery fire of the naval formation at this moment can reimburse the strength of a brigade of him.

Ji Jialiang suppressed his anger and watched the continuous smoke and explosions. After all, discord between the army and the navy is no longer a matter of a day or two. Even His Majesty the Emperor can't help it. What can he do as a mere lieutenant general Method?

The shelling by the navy was extremely violent. Liu Gongdi, who was hidden in the reeds near Datongkou, judged from the sound of the Japanese shelling and the intensity of firepower that the Japanese army might have dispatched a large warship, so he immediately launched the torpedo boat and checked the torpedo pressure again. Article 171 The four British-made torpedo boats, No. 93 Wen, No. 88 Wen, and No. 42 Wen, started their engines successively to warm up.

But the Wen 171 boat commanded by Liu Gongdi suddenly suffered a mechanical failure, and the pressure of the torpedo was abnormal?It may also be judged that the air supply copper pipe was damaged by Japanese shrapnel in Xiaguan. The gunner and chief engineer were nervously troubleshooting, but the opportunity must not be lost. Therefore, the Wen 93 boat under the command of Wu Shirong, Xie Yanchi, and Huang Yunbai The No. 88 boat and the Wen No. 42 boat were under the unified command of Xie Yanchi to attack.

Although the range of activities of the Japanese ship in the river is extremely small, the 450 mm British torpedoes are relatively weak, and it is difficult for a torpedo launched at the frontal angle of attack to hit the Japanese ship at the frontal angle of attack. Even if it hits, it may slide away. Therefore, Xie Yanchi decided to use the Wen 93 boat, the Wen 88 boat, and the Wen 42 boat to form a parallel battle formation to meet the enemy, advance from the left, middle and right respectively, and launch torpedoes from the two wings at a [-]-degree angle.

Wen 93, Wen 88, and Wen 42 cut through the waves and headed straight to Yanziji, where the Japanese formation was located. The observation post of the Yanziji Fort was the first to spot the formation of torpedo boats. Chang Bo and Li Minglei went to the observation post. Obviously, the Japanese warships also spotted the fast-approaching torpedo boats of the Chinese Navy.

Mataro Tanimoto immediately ordered the ships to form a line behind Yaeyama. The destroyer's side turned to [-] degrees, and the firepower of the whole ship intercepted it. The rest of the ships intercepted with the gunfire of the bow. , the water column splashes in all directions.

Xie Yanchi calmly watched the Japanese warships making formation adjustments. The Wen 88 boat attacking the middle road was actually playing the role of a death squad, trying to attract Japanese firepower, but obviously the Japanese were not so easy to deal with. Matsuro Tanimoto adjusted his response The plan made Xie Yanchi's plan come to nothing.

The torpedo boats are speeding on the river at a high speed of 45 knots. Compared with the speed of 36 knots of the new Japanese destroyers, the performance of these British Henry torpedo boats is far behind, but this is the only batch of Chinese navy that can still fight. And the surface ships that are still fighting, the massacre of the Japanese army in Xiaguan made Xie Yanchi and others have red eyes.
