The <entity_0> (Chinese: 清川江战役; pinyin: Qīngchuānjiāng Zhànyì), also known as the Battle of the Ch'ongch'on, was a decisive <entity_6> in the <entity_5>, and it took place from <entity_2> to <entity_3>, along the <entity_1> Valley in the northwestern part of <entity_4>. Hoping to repeat the success of the earlier First Phase Campaign, the PVA 13th Army first launched a series of surprise attacks along the <entity_1> Valley on the night of <entity_2> at the western half of the Second Phase Campaign (Chinese: 第二次战役西线; pinyin: Dì'èrcì Zhànyì Xīxiàn), effectively destroying the Eighth United States Army's right flank while allowing PVA forces to move rapidly into UN rear areas. In the aftermath of the <entity_6>, the US Eighth Army's heavy losses forced all UN forces to retreat from <entity_4> to the 38th Parallel. Between October 25 and November 4, 1950, the PVA 13th Army surprised and defeated the Republic of <entity_7> Army (ROK) II Corps and the US 1st Cavalry Division in a series of battles around Onjong and Unsan, destroying the right flank of the US Eighth Army while forcing the UN forces to retreat back to the <entity_1>. The <entity_6> was fought along the UN front line around the <entity_1> and its tributaries, which is located 50 mi (80 km) south of the Sino-Korean border. The UN front line stretched horizontally from the Korean west coast to the Taebaek Mountains in central <entity_7>, while the <entity_1> crosses into the north of the UN line at the town of Kujang-dong. During the chaos of the <entity_6>, Major General Yu Jae-hung of ROK II Corps did not receive news from the front line until midnight of <entity_2> — five hours after the Chinese had entered the ROK rear. On the night of November 24, the defending PVA 66th Corps counterattacked the Koreans with infantry and cavalry charges, and the PVA and ROK troops were soon locked in a seesaw <entity_6> from <entity_2> to 26. The ROK casualties could not be estimated due to the complete absence of South Korean records during the first half of the <entity_5>, but according to Paik, the ROK II Corps' headquarters was forced to disband in the aftermath of the <entity_6>. Having decisively won the <entity_6> and once again turned the tide of the war in favor of the Communists, the <entity_0> represented the peak of the Chinese military's performance in <entity_7>.
