"Task Force Kean" launched its attack on August 7, moving out from Masan, but Kean's attack resulted in a meeting engagement with one being simultaneously delivered by the KPA. Heavy fighting continued in the area for three days. By August 9, "Task Force Kean" was poised to retake Chinju. The Americans initially advanced quickly though heavy KPA resistance. On August 10, the Marines picked up the advance. However, the 1st Provisional Marine Brigade was withdrawn from the force on August 12 to be redeployed elsewhere on the perimeter. "Task Force Kean" continued forward, capturing the area around Chondong-ni. Eighth Army requested several of its units to redeploy to Taegu to be used elsewhere on the front, particularly at the Naktong Bulge.
