1941

Mourne Gaels first pitch at Moor Road, in a field of Paddy O'Hanlons. However, before their first League game the goal posts were cut down and they eventually played in Currans field (now Dunnaman Park) at the top of Scrogg Road. The Gaels has a fairly successful season well up in the League and beaten in the Semi-Final of the Senior Championship by a strong Bryansford outfit. Reports due to the war were very sketchy and games were not played in any definite pattern due, no doubt, to travel and petrol restrictions. Teams in the League were Mourne Gaels, Warrenpoint, Bryansford, Mayobridge, Glenn, Downpatrick, Newry.

1942/1946

After having lost their pitch, St Colman's Park, and the need of a short amalgamation (Mourne Gaels) with Ballymartin the Young Emeralds played for a season in Curran's field. However, due to a number of players leaving the area in search of work, coupled with the difficulty of travel and supplying transport the Club withdrew from the League. Some Kilkeel players, notably Charlie McConville and Brendan McManus played their football with Bryansford. In 1946 the Young Emeralds were re-formed and played Longstone in a challenge match and lost 1-3 to 1-2. Their competitive match appears to have been in the Feis Sevens on 26th May.
