The BATTLE OF CHENGPU (simplified Chinese : 城濮之战; traditional Chinese : 城濮之戰) took place in 632 BC between the State of Jin and the State of Chu and its allies during the Spring and Autumn period of Chinese history. It was the first great battle in the protracted conflict between the states of the Yellow River valley, and the states of the Yangtze River valley. The Jin victory confirmed the hegemony of Duke Wen and checked Chu ambitions in the north for at least a generation.

Following the death of
Duke Huan of Qi in 643 BC, the state of Chu
steadily extended its influence northward, absorbing half a dozen
smaller states as its satellites. In 636 BC, Chong'er, a ducal prince
of Jin, after spending fifteen years in exile traveling throughout
numerous states, came to power as
Duke Wen of Jin
In the years leading up to 632 BC, conflict between Jin and Chu became increasingly public and was characterised by frequent shifts in alliances between the various small states that lay in a narrow band of land between the two larger states.
King Cheng of Chu
As promised by Duke Wen to King Cheng during his exile in Chu, the Jin army retired "three days march" (退避三舍) (45 km) before camping on the plain of Chengpu on the border of Wei and Cao, awaiting a decisive battle The retirement also linked the Jin forces up with Qi and Qin reinforcements.
Only the central force of the Chu under Prime Minister Ziyu (子玉) was made up entirely of Chu troops. The left wing under Zixi incorporated soldiers from Chu's close satellites Shen and Xi. The right wing under Zishang comprised completely a separate detachment from the armies of Chen and Cai, perhaps numbering around a third (?) of the entire force.
The Jin force was expanded before the expedition from two armies into three: the upper, the central and the lower; these three were then regrouped into wings before the battle: the upper army at the right wing under commander Hu Mao and vice-commander Hu Yan , lower at left under Luan Zhi and vice Xu Chen , central remained at centre under Xian Zhen and vice Xi Zhen . Duke Wen did not direct or engage in the fighting.
On the fourth day of the fourth month of 632 BC, the rival forces met.
The battle commenced with the advance of both wings of the Jin army. The Chu right wing was reckoned to be the weakest and Xu Chen, commander of the Jin left wing, attacked. Xu armoured his chariot horses with tiger skins and launched an urgent, vigorous assault on the Chu right wing. The attack was rapidly successful, scattering and demolishing the enemy wing completely.
The Jin left then became a holding force, fixing the Chu center and preventing it from attacking the Jin centre or aiding the Chu left wing, since in either case the Jin left would have taken it in the flank and rear. Meanwhile, Hu Mao's Jin right wing had skirmished with the enemy, faked a retreat and carried with them the two great banners of the Jin commander-in-chief himself. The Chu left, made up of levies from the states of Shen and Xi, thought that the Jin right wing had lost and Ziyu ordered a pursuit. A contingent of chariots under Luan Zhi swept in front and dragged tree branches to raise a dust cloud and thereby obscure the movements of Hu Mao's men who were circling and reforming.
The Jin left aided by the Jin center continued to maintain their positions against the Chu center. Though the Jin centre was temporarily disordered by an intense whirlwind, it was effective in preventing the Chu center from supporting its left wing. As the Chu left advanc
