The Battle of Kinma Island, also known as the Battle of Kinmen, was the only complete "defeat" of the Chinese People's Liberation Army, and 9,000 Chinese the entire ARMY was destroyed.
The Battle of Jinma Island was the fundamental reason why the People's Liberation Army lost its entire army because it did not have a navy, and after this campaign, the pace of the development of the navy by the Chinese People's Liberation Army was accelerated.

In the fierce Battle of Jinma Island, more than 9,000 PEOPLE's Liberation Army troops were completely destroyed
On October 24, 1949, just 24 days after the founding of New China, it entered the Chinese People's Liberation Army in Fujian in July, and was responsible for the Tenth Corps of the Third Field Army (Sanye) of the Chinese People's Liberation Army. The commander of the Tenth Corps was Ye Fei, who launched the Battle of Fuzhou, the Battle of Pingtan Island, and the Battle of Zhangxia, just a few days after the end of the Battle of Zhangxia.
Chinese people's liberation army decided to launch an offensive against the Kuomintang on Kinmen Island and take Kinmen Island in one fell swoop. Before this, the People's Liberation Army was in a strong position, but the Battle of Kinmen Island became "the only complete defeat of the People's Liberation Army in the Liberation War."
Kinmen Island is one of the many islands in Xiamen, the nearest place is only a few kilometers away from Xiamen, but it is more than two hundred kilometers away from Taiwan, which can contain the port of Xiamen and is a barrier in southern Fujian.
On October 24, 1949, the People's Liberation Army, which had been destroying all the way, decided to launch an attack on Kinmen Island, and more than 9,000 people from three regiments under the 28th Army of the People's Liberation Army were the first echelon, and they took more than 300 wooden sailing ships and began to cross the sea at 9 p.m. Landed on Kinmen Island around one or two o'clock in the morning of the 25th!
This was the first landing operation of the Chinese People's Liberation Army to cross the sea, and a lot of preparations were made before the war to ensure the victory of the campaign. But the end result is something that no one wants to see.
The exact timing is less precise, as the PLA involved in the fighting is largely unsaved. After landing, the People's Liberation Army immediately occupied the Potou position and launched an attack on the island.
The Kuomintang troops on Kinmen Island began to counterattack, and the root cause of the total destruction of the PLA army was that the Kuomintang blew up all the ships of the PLA landing force.
At that time, the People's Liberation Army recruited all the ships that could be recruited near Xiamen to cooperate with the landing operations of the cross-sea troops. When the first echelon transported more than 9,000 PLA people to Kinmen Island, all the ships were put into battle.
The air force and navy of the Kuomintang army blew up all the ships crossing the sea, and the three regiments of the troops that landed on the island did not have a unified commander, and after landing on the island, although they began to win victories. Attacks on the island were also relatively smooth.
In the ensuing battle, it became a lone battle, because at this time there were more than 40,000 Kuomintang troops defending the island, and these Kuomintang troops were supported not only by aircraft and artillery, but also by the Kuomintang Navy.
There is also a tank battalion on the island, equipped with 21 tanks. At that time, the People's Liberation Army thought that there was only Li Liangrong's "Doujia Army" on the island. At that time, the guard in charge of defending the Golden Gate was Li Liangrong's Twenty-second Army, and when their legion arrived at Kinmen Island, Tang Enbo was accompanied by Li Liangrong to watch.
At that time, after the soldiers got off the ship, they were all dressed in rotten civilian clothes. Tang Enbo also thought that it was a civilian husband, and as a result, Li Liangrong said that this was his soldier, and each soldier also brought a bucket hat, which was called "bucket soldier" by the people of Kinmen Island.
At that time, the intelligence of the People's Liberation Army was that 20,000 fighters were defending Kinmen Island, and if so, 9,000 People's Liberation Army could also win. As a result, the strength of the army on the island reached more than 40,000 people.
A large number of fortifications, forts were also built. And support for tanks, warships, and bombers. The fighting was extremely brutal. Although our People's Liberation Army has called for artillery support, the number of artillery that can be supported is still limited!
The officers and men of the second echelon waiting to cross the sea on the shore could only watch as our ships crossing the sea were destroyed and ignited in a raging fire and were powerless. The fighting on the island lasted for three days.
The officers and men of the second echelon watched helplessly on the shore, and many soldiers cried. Because there were no ships to cross the sea to support, they could only watch their comrades die.
This battle was also the only "complete defeat" of our People's Liberation Army in the Liberation War. After the war, many reasons were summarized, and I think the main reason was one. The PLA did not have a navy at that time.
There were no ships, and if there were a navy at that time, even a few warships, we could send some reinforcements to the island and win the battle.
After the battle, the People's Liberation Army realized the importance of the navy and accelerated the pace of building the navy.
