To some extent, the legend of Zheng Chenggong begins with his father Zheng Zhilong. Zheng Zhilong is a native of Shijing Town, Nan &;an, Quanzhou, Fujian Province. In his early years, he served as an interpreter in the Dutch fleet. At that time, the Dutch never dreamed that it was this Zheng Zhilong and his son Zheng Chenggong who subverted the Dutch hegemony in East Asian waters. At that time, the Netherlands had a larger fleet than Portugal, Spain, France, England, Scotland and Germany combined, and was known as the sea coachman. The Dutch fleet, which roamed the world&;s oceans, met its real rivals only after it met Zheng Zhilong&;s fleet: Zheng Zhilong firmly controlled the routes from North to Belgium, from today&;s Singapore in the south to the Indian Ocean in the west, and the fleet once reached as many as 3,000 ships. Before Zheng Zhilong surrendered to the Ming Dynasty, the governor of Fujian in the Ming Dynasty induced the troops of the Dutch East India Company to attack Zheng Zhilong on the condition of permission and legal trade. As a result, the fast ship Orvo of the Dutch fleet was sunk and its crew was captured by Zheng Jun. After that, for quite some time, Dutch ships were afraid to haunt the South China Sea because of Zheng Zhilong&;s reputation. In September of the fifth year of Chongzhen, the pirate Xiang Liu led thousands of people and 170 ships to plunder Fujian. At this time, Zheng Zhilong, who had accepted the acceptance of the Ming Dynasty, sent troops to resist as a general of the Ming Dynasty. At that time, Xiang Liu&;s ship was equipped with more than 10 Red Yi cannons, while Zheng Zhilong led 3,000 elite soldiers, 40 warships and 500 ware to fight and finally forced Xiang Liu to flee. On October 22, 1633, Zheng Zhilong, as a general, confronted the Dutch navy in Boluo Bay on the southeast coast of Kinmen: Zheng Zhilong&;s fleet appeared at the mouth of Boluo Bay at dawn that day, and the Dutch navy and Liu Xiang&;s men dispatched 59 ships (including 11 latest heavy warships) to meet. In contrast, Zheng Zhilong&;s fleet has more than 150 warships, which has absolute strength and weapon advantages. Zheng Zhilong first broke into the Xiang Liu fleet with a type of fireboat, disrupting the enemy formation, and then the main fleet concentrated its superior forces and firepower on the Dutch fleet. In the end, the Dutch Xiang Liu joint fleet lost 50 warships and captured more than 100 people. After the Battle of Luowan, Zheng Zhilong chased the Dutch fleet out of the coast. In the eighth year of Chongzhen (1635), Zheng Zhilong and Xiang Liu fought a decisive battle in Hiroshima and won a decisive victory. In this battle, Zheng Zhilong annihilated the Xiang Liu fleet in one fell swoop, and Xiang Liu himself committed in this battle. In the 12th year of Chongzhen (1639), nine Dutch warships invaded the coast again, and the Zheng Zhilong Fleet sank five of them with fireboats and sailors carrying gunpowder barrels. At this point, Zheng Zhilong has completely mastered the sea control right in the South China Sea. Any ship that passes through the South China Sea must obtain the flag awarded by the Zheng family in advance, otherwise it will encounter a head-on blow. Essentially, the Zheng family is a maritime-military complex group with both military and commercial intelligence. It is with its strong military strength that Zheng Zhilong can monopolize the trade in Zhancheng, Luzon, Beigang, Hirado, Nagasaki, Mumbai, Bandan, Jiugang, Malacca, Cambodia and Siam. At this time, Zhengjiaqi had 20,000 soldiers of different races, including Han Chinese, Japanese, Koreans, Vietnamese and even African blacks, with more than three.A fleet of thousands of large and small ships. Zheng Chenggong took over the most powerful naval force in East Asia at that time. He relied on the powerful naval force as a support to control the trade routes in Southeast Asia, established a five-merchant system of mountains and seas, and obtained huge military salaries from the trade network connecting the East Atlantic. In terms of weapons and equipment, Zheng Chenggong&;s fleet is no different from the European fleet: the main warship of the Zhengjia fleet, Daqingtou, is about 10 feet long, 2 feet wide, 5 feet high, 8 feet draught, and has a load of three or four thousand tons. In the battle with the Dutch and Xiang Liu, the Zheng fleet was equipped with Red Yi and Weiyuan cannons, some of which weighed two or three thousand kilograms. In fact, an arms race has been going on in East Asia for nearly a hundred years from the outbreak of the Wanli War to resist Japan and aid Korea in 1592 to the expedition of Gerdan by Emperor Kangxi in 1690. First, various new firearms of Ming Dynasty, Korea and Japan appeared on the Korean battlefield. Then the post-Golden Eight Banners rose in Baishan Blackwater in the northeast; Then the Dutch invaded Penghu, and scuffles broke out with colonists such as Portugal and Spain. In 1661, Zheng Chenggong recovered from the Dutch colonists; In 1683, Shi Lang pacified Ming Zheng; From 1685 to 1688, the Qing army launched a self-defense counterattack against Russian troops occupying jaxa and other places; In 1690, Emperor Kangxi personally recruited Gerdan. In this century&;s war experience, all kinds of new weapons have taken turns in this area. The Zheng fleet has absorbed the advantages of all kinds of firearms, and is equipped with domestic firearms and red Yi cannons imported from Europe. In the spring of 1661, Zheng Chenggong led more than 25,000 officers and men across the sea in more than 300 boats to recover the islands occupied by Dutch colonists. At that time, the Dutch East India Company didn&;t actually occupy the whole island, but just set up Plomin Castle and Geran Castle as trading posts. The total number of Dutch troops stationed on the island was only several thousand, and the warships were only four armed merchant ships of the East India Company. There is no generation difference between the two sides in terms of weapon performance, and Zheng Chenggong&;s navy has completely gained the absolute strength advantage over the Dutch colonists. Four armed merchant ships of the Dutch East India Company were besieged by hundreds of warships of Zheng Chenggong&;s navy in the battle of Plomin, and eventually one sank and three fled. After taking the ordinary people as a stronghold, Zheng Jun immediately besieged the city of Geran by sea and land, where Zheng Jun encountered strong resistance from the Dutch, so Zheng Chenggong sent his men to settle the field on the island on the one hand, get supplies through overseas trade on the other hand, and adopted a protracted war strategy of encircling and not attacking the city of Geran. The local Gaoshan people and the Han people spontaneously helped Zheng Chenggong&;s troops. Eventually, after the siege of the city of Geran for more than seven months, the ammunition was exhausted, more than 1,600 officers and soldiers were killed and the water source was cut off. At this time, all the hopes of the Dutch colonial army in the city of Geran were pinned on the reinforcements from Batavia. In July 1661, Dutch reinforcements consisting of more than 600 soldiers and 11 warships arrived, and they also brought a lot of supplies to the city of Gerenza. At this time, Zheng Chenggong sent his troops to various places to reclaim land and appease people&;s hearts. He was already fully engaged in the development and management after recovery, so his troops were in a state of dispersion, which made the Dutch colonists think that it was organic and profitable. In mid-August, Holland and ZhengzhouThe Dutch army launched a fierce naval battle in the inland sea of Taijiang. In this battle, Zheng Jun sank a Dutch warship and seized several ships. Since then, the Dutch army has lost the ability to take the initiative to attack. In December, a Dutch noncommissioned officer defected and provided Zheng Chenggong with information about the city of Geran. Zheng Chenggong immediately organized a continuous bombardment of the city of Geran, and the Dutch, who had no skills at all, finally surrendered and returned to the embrace of the motherland after more than 30 years of occupation.
