27 Battalion

Have only just received my Dad's war record which is proving challenging to read. He joined the Royal Marines as a boy bugler at 14. in 1944 when he reached 18 he joined the commandos in th 27th Battalion. This Battalion seems to have very little information. He stayed in the commandos until he left in 1955. His name was Ronald Edwin Sargeant. Does anyone know what happened to the 27th Btn?
