With the pressure somewhat relieved following the amphibious landings at Inchon on 15 September, the brigade joined the subsequent breakout from Pusan, and then covered the flank of the main US advance aimed at retaking Seoul. On 22 September the brigade crossed the Naktong by a hurriedly constructed bridge that could only be walked over in single file. To secure the road on the other side, the brigade, now attached to 24th Infantry Division (United States), was ordered to take high ground on either side. To the right of the road were "Plum Pudding Hill" (their name for it), three miles south of Songju, and a 900-foot high feature which later became known as Middlesex Hill. The Middlesexes, supported by two American tanks, took Plum Pudding at the point of the bayonet, and then took Middlesex Hill. Total casualties were one officer and six other ranks killed and seven wounded. Now the brigade had to take the high ground on the left of the road. Early on 23 September the Argylls began the Battle of Hill 282, suffering the heaviest casualties so far as a result of both heavy fighting with North Korean force and a communications failure which led to an attack by US aircraft in a "friendly-fire" incident. The Argylls' second in command, Major Kenneth Muir was awarded a posthumous Victoria Cross for his efforts (ultimately unsuccessful) to hold the position. In total the Argylls suffered two officers and eleven other ranks dead, four officers and seventy OR wounded, and two missing, about forty percent of these casualties being from the US airstrike. Despite this setback the brigade participated in the capture of Songju on 24 September, working with 1st Battalion, 19th Infantry Regiment (United States). The brigade was then detached from 24th Division, and placed under the command of Eighth United States Army.
