Attached to the U.S. 24th Division, this Brigade participated in the northward advance operation as a U.N. Forces' leading unit after capturing Pyongyang and crossing the Cheongcheon River.
They faced stiff resistance by the North Korean Army equipped with tanks at Jeongju but they defeated the North Korean Army to capture Jeongju.

Battle of Bakcheon (1950. 11. 4~6)
This was the battle in which U.K. Forces fought against the Chinese Communist Forces for the first time. As the Chinese Communist Forces began the big offensive from Oct. 25 after their participation in the Korean War, the British 27th Brigade carrying out preliminary duties at Jeongju moved to Bakcheon and assisted the withdrawal of the U.N. Armed Forces (the U.S. 24th Division, the U.S. 1st Cavalry Division). Afterwards, it fought against the Chinese Communist Forces chasing the U.N. Forces that were withdrawing. The 27th Brigade faced a crisis in this battle because the Artillery Battalion supporting them was taken over by the Chinese Communist Forces and the retreat path to the Cheongcheon River was blocked. However, it was able to sustain the Bakcheon area by defeating the enemy with counterattacks. This battle greatly helped the U.N. Forces to secure the Cheongcheon River bridgehead during the Chinese Communist Forces' 2nd offensive.

This Brigade helped the retreat of the U.N. Forces by defeating the Chinese Communists series of full scale attacks for 3 days and allowed the U.N. Forces to form a new defense line in the north of Seoul. However, this Brigade lost approximately one fourth of their force during this battle. Gloster Battalion of this Brigade was surrounded by 2 divisions of the Chinese Communist Army divisions in all directions and only 39 members from this Battalion were able to escape.
