I want to know the answer to the following question:
When did the Chinese and US military have their first confrontation in Korea?
All the background I'm provided with is that "After decimating the ROK II Corps at the Battle of Onjong, the first confrontation between Chinese and U.S. military occurred on 1 November 1950; deep in North Korea, thousands of soldiers from the PVA 39th Army encircled and attacked the U.S. 8th Cavalry Regiment with three-prong assaults—from the north, northwest, and west—and overran the defensive position flanks in the Battle of Unsan.". Is that enough to answer the question?
