 Although the KPA had suffered heavily in the preceding weeks, they continued to resist strongly, while a lack of accurate maps and the narrowness of the roads made rapid movement difficult for the advancing UN forces.During this time 3 RAR had a platoon of American M4 Sherman tanks attached and a battery of field guns in direct support.The 27th British Commonwealth Brigade subsequently moved from Kumchon, with the Argylls capturing Sariwon on 17 October, killing 215 KPA and taking many prisoners for the loss of one man killed and three wounded.
