Tarfside is a small hamlet in Angus, Scotland. It is situated in the upper course of the Glen Esk valley of the River North Esk around 8 miles north of Edzell, and has a footpath to nearby Loch Lee. Tarfside is a very beautiful place for walkers.
During WW2, a secret unit was based in the area known as the "Tarfside Patrol" This was led by Sgt W.D.Kidd, who reported to the Group Commander Captain H.A.Ferrier, and Asst G.C. Liuet A.J Mackie. An underground base would have been made which the patrol would have gone into hiding if the German's had invaded. Research by the British Resistance Archive / Coleshill Auxiliary Research Team have identified the patrol members but as of yet not the operational base (bunker)
