 16th Field Regiment, Royal New Zealand Artillery and support elements arrived later during the conflict from New Zealand.The force arrived at Pusan on New Year's Eve and on 21 January joined the British 27th Infantry Brigade.The New Zealanders immediately saw combat and spent the next two and a half years taking part in the operations (most notably the Battle of Kapyong and the First Battle of Maryang San) which led the United Nations forces back to and over the 38th Parallel (with the NZ naval vessels being especially active in the inner Han River estuary), later recapturing Seoul in the process.
