At this time, Kublai Khan had not yet destroyed the Southern Song Dynasty, so he only occupied northern China, and the Yuan Empire was gathering heavy troops to prepare for the southern expedition, so the army used to attack Japan was not very large, only about 25,000 people, and the Han people were not the main force of the army. Therefore, this time the Yuan Dynasty failed to conquer Japan, and it cannot be ruled out that there was a reason why the Southern Song Dynasty gave Japan a blood resistance.

In 1274 A.D., the Yuan Dynasty sent an army to attack Japan sailed from Korea to the island of Kyushu, and of the 25,000 men of the expeditionary force, about half were Mongols and Goryeo, in addition to a small number of Jurchens and Han Chinese. The commander of the army was the Mongol Kudun, and the two deputy commanders were the Goryeo Hong Chaqiu and the Han Liu Fuheng.

The Yuan army sailed Hakata Bay, first captured and ravaged Tsushima Island and Iki Island, and then landed in Kyushu in three routes, preparing to capture the Japanese hinterland. The place of landing of the main forces was approximately near Nagasaki.

In the face of the first "Mongol attack", the Japanese Kamakura shogunate mobilized some regular troops to meet the battle, and the coastal feudal clans of Kyushu also urgently organized samurai and militia to participate in the war.

The fierce battle lasted for more than 20 days, and at the beginning, the Japanese did not adapt to the tactics of the Yuan army, suffered heavy losses, and suffered huge casualties. At that time, the Japanese samurai still used hand-to-hand combat as the main combat method, and they were really educated in front of the Hui Hui artillery and archers of the Yuan Dynasty. However, they still relied on their own martial arts and the spirit of fighting to the death, and successfully organized the advance of the Yuan army.

After a few days of fighting, the Japanese gradually adapted to the way the Yuan army fought and began a counteroffensive. The Japanese heavy cavalry, composed mainly of Japanese samurai, was particularly valiant, and with the support of archers, they braved the rain of arrows to charge the enemy and engage the enemy in hand-to-hand combat, rendering the Mongols' bow and arrow superiority nullified. Liu Fuheng, deputy commander of the Yuan army, was killed in a fierce battle.

The Yuan army retreated to the beach after losing most of the losses, relying on the return artillery defense, so far the Yuan army suffered heavy casualties, the progress was hopeless, their defeat was inevitable, because the arrows and supplies were about to run out, the Yuan army could not continue to hold the position, they had to retreat on the boat.

On the way back to Korea, the Yuan fleet was hit by a storm and suffered some losses, but most of the ships returned safely.

In other words, when Mongolia made its first conquest of Japan, it encountered a typhoon only after its defeat, and the typhoon only played a role in icing on the cake for Japan.

This crusade allowed the Mongols to encounter an opponent in East Asia who was no less equipped and trained and courageous than themselves. The Koreans were mainly responsible for close combat in battle, so they suffered heavy losses from the frontal onslaught of the Japanese.

Therefore, the Korean people are very impressed by the combat effectiveness of the Japanese samurai, especially the Japanese katana, according to their records, the sword of the ordinary Yuan army and the Japanese katana are broken when they touch, and the knives in their hands are cut off, only the handle of the knife is left, how to fight with others, the plot of grabbing the white blade empty-handed only happens in martial arts, you must know that the other party is also a well-trained killer, can you guarantee that your body will not be hit by the sword he is used to?

This battle also fully illustrates that the Mongol soldiers, who were known for their bravery, were also very chicken thieves, most of them used bows and arrows, hid behind the formation, and handed over the hand-to-hand combat work to the Goryeo soldiers, so their casualties were not too large.

Afterwards, the Mongols commented on the Japanese army, not particularly admiring their bows and arrows, believing that although their bows and arrows had a certain power, they had a relatively short range, but like the Koreans, they left a deep impression on the Japanese swords.

Here is a brief introduction to the Japanese katana, the Japanese katana originated from the horizontal knife of the Tang Dynasty, during the Sui and Tang dynasties, Japan did not have its own forging knife technology, and it was entirely by imitating and learning Chinese knife-making technology to produce swords, and most of the Japanese swords at that time maintained the basic characteristics of the Han Dynasty ring head knife.

In the battle of Baijiangkou with the Tang Dynasty, because the ability and flexibility of the Tang Dynasty's horizontal sword to cut and break armor far exceeded that of the Japanese sword of the same period, the Japanese samurai wearing leather armor had no protection against it, and the Japanese elite was defeated, and then the Japanese mainland fell into extreme fear.

After a few years of panic, the Japanese recognized their own strength, so they began to learn from the Tang Dynasty with a humble attitude, and many of the envoys sent by Japan to the Tang Dynasty were skilled craftsmen, bringing back the forging technology of the Tang Dynasty's horizontal sword back to Japan, and after imitation and research, they gradually forged the Japanese samurai sword, which is known as one of the world's three famous blades.

The other two world-famous knives are the Damascus knife of the Islamic tribes (India, Iran, Afghanistan, Bukhara, Turkey, etc.), this knife is a high-grade alloy steel, the smelting technology is very complex, the cost is high, the specific production process is now lost. In ancient times, Damascus knives were generally only available to nobles.

As well as the Malayklux sword in Malaysia, people didn't care about the Malayklux sword at first, until the Malays armed with the Malays in the Malays fought many wars with the Malays in the Malaysian area, which made the Malayklux sword famous.

According to historical records, the Malayklux sword could cut through the steel barrel of the Dutchman's musket at once, and it was very sharp to penetrate the armor with a slight push of the hand.

It's a pity that after the Westerners conquered the Malay Archipelago, out of fear of this weapon, they began to prohibit the Malays from forging and wearing, and the forging process of the Malay Clux sword is very complicated, and it takes more than 500 times to repeatedly hammer and forge into the fire, and the required material must be the meteorite iron, so it is lost.

In contrast, the Japanese samurai sword does not have much characteristics, but its advantage is that it does not require much hard-to-find materials, and its superiority mainly comes from its unique post-quenching process, so the cost is relatively low, and ordinary soldiers and civilians in Japan can have a good sword.

To be sure, the Mongol soldiers at that time were incapable of enduring hardships and hardships, and they could survive by eating raw horse meat and drinking horse blood if necessary. The Mongols fought mainly by mobility, and they fed the war with war, grabbing wherever they went, so they generally rarely brought sustenance. However, in this war, the Mongols have not been able to use their strengths, and have never been able to break into the hinterland of Japan and plunder supplies.

The Japanese were clever at keeping their enemies out of the country, but they also needed to be backed up by their strong fighting power, otherwise they would not have been able to hold out until the Mongols ran out of ammunition. (Once Literature Network,)
