The Seolmacheon in South Korea is a tributary of the Imjin River, which it joins at Jeokseong, and it was on Gloster Hill, between the two rivers, that the British Gloucestershire Regiment made their last stand against the Chinese in the Battle of the Imjin River, a major event in the Korean War, from 22–25 April 1951. There is a permanent memorial here (37°56'33.78"N, 126°56'21.00"E) and the British Embassy in Seoul organises a service here every April to commemorate the event.
