Madang Rocky Mountain looks like a galloping horse, lying across the Yangtze River, and its rock head stands at a 90-degree angle in the middle of the river. Facing Mian Chuan Dao, a sandbar in the middle of the river, the river surface is squeezed into a narrow place.
On the cliffs around Jitou, before the Anti-Japanese War, the National Government successively built a three-stage river-locked fort here, and built an unbreakable Madang fortress area.
The primary battery is built in a depression of the horse's head, which is natural and hidden. The heavy artillery here sank many invading Japanese ships.
At the secondary battery, there is a tunnel with a length of about 50 meters and a shape of "",which still retains the heroic spirit of that year. The ground and walls of the tunnel are paved with large pieces of bluestone. The dome of the tunnel is made of blue bricks with a carefully designed vent hole in the middle. The blue bricks are filled with a mixture of rice pulp, lime and tung oil. Cannons can be placed in tunnels at ordinary times, and artillery bombardment can be launched once enemy ships attack in the river; When the enemy strikes back a little harder, he can also drag the gun back to the hole to hide.
Third-level battery is placed behind a boulder by the river, and heavy machine gun positions, mainly the main positions of border guards, are set up to prevent the enemy from forcibly landing and attacking the battery along the river.
On the eve of the Japanese attack, the Kuomintang government was still about 500- 1000 meters downstream of the Rocky River, and the sunken ship built a barrage-like barrier line across the banks. Around the blockade, there are 30 artificial reefs and 1600 mines. If it is combined with the third-class fort and bunker on the shore, it can be called a natural barrier.
But it turns out that no matter how good the natural barrier is or how strong the fortress is, it needs a three-dimensional protection system. To hold the fortress, you need both air support and comrades-in-arms to help you protect the back of the fortress.
The fall of Madang was just a detour.
Visiting the terrain around Madang, I found that there are gentle hills, hills and lakes in all directions except the riverside of Madangji. With the strong intervention of the enemy's superior naval and air forces, as soon as China's army appeared on the highway, I'm afraid it would be deeply ploughed by Japanese planes first. To say the least, even if reinforcements were timely, relying on those hills, China's army, which was not strong in fighting capacity and poor in equipment, could not even keep the fortified positions of military forces, and at most lost the lives of more than 10,000 soldiers. It would be futile to delay the Japanese attack for a day or two!
Director Peng, who has served in the East China Sea Fleet for many years, lamented: Madang is a real example. The strength is not as good as people, and they are passive everywhere. You will be beaten if you fall behind.
