In BC 1050, Ji Chang, Zhou Wenwang, died, and Ji Fa, the heir to the throne, namely Zhou Wuwang and King Wu succeeded to the throne, to show that he was still adhering to the destiny of King Wen and continued to take advantage of the opportunity of Shang Dynasty to temporarily expand eastward. BC 1048, two years before the Battle of Makino, Zhou Wuwang observed soldiers in Jin Meng (now Mengjin County).
In Historical Records, it is said that "eight hundred princes joined Tianjin unexpectedly", but it is not "meeting unexpectedly". According to Oracle Bone Inscriptions's records, many countries participated in the invasion of Guanzhong and Jianghan, but I'm afraid there were not as many as 800 vassals. Judging from the situation of Mu Ye War, it is basically a Qiang and Rong country in the southwest.
At this time, there was a fierce civil strife in Shang Dynasty. Di Xin killed his uncle Beagan and imprisoned another uncle, Ji Zi. Other nobles involved, such as Cabbage, sized up the situation and defected to Zhou Guo. King Wu undoubtedly got a lot of confidential information about Chao Ge from the nobles of the Shang Dynasty. When the time was ripe, King Wu decided to send troops to attack the merchants, and at the same time informed the allies in Jin Meng to send troops with the allies.
The strategic plan of cutting merchants is: while the main force of Shang Dynasty was stranded in the southeast, the elite troops went deep into Ji Wang with lightning speed, defeated the defenders, captured the merchants in one fell swoop, occupied the political center of Shang Dynasty, disintegrated the regime of Shang Dynasty, and made the remaining merchants and their countries leaderless, and then defeated them one by one.
There is a description in the Book of Songs Daming, which is called "attacking (attacking) the big business" or "attacking (attacking) the big business quickly", which is quite similar to the "blitzkrieg" of the German army in World War II.
War result
"The prisoner of Iraq" records that King Wu won a great victory in the battle of Makino, killing180,000 people, capturing 330,000 people alive, hunting rhinoceros, tigers, bears, deer and other animals, and obtaining a lot of jewelry and property. Everyone in Yi Rong Yi has armor. After the victory, King Wu stabbed Zhou Wang's body with "Guanglu", and then Zhou Wuwang conquered the local governors of Shang Dynasty, expelled Fei Lian, the general of Shang Dynasty, and wiped out the remnants of Shang Dynasty one by one.
Before the Qin Dynasty, China had a tradition of "rising and falling the country, succeeding the peerless", so it still retains the fief of Wu Geng. Besides, Zhou Wuwang's army is limited. After the Battle of Makino, the team of merchants going south was not completely eliminated, and some teams stayed in Dongyi until the time of Zhou Chengwang and Duke Zhou's eastward expedition.
