'Redshank' was a British operation by the Special Operations Executive against the Baardshaug converter and transformer station which controlled power to the railway between the Orkla pyrite mine and the port of Thamshavn (4 May 1942).
Three Norwegian operatives of the SOE was landed from the sea and successfully attacked the facility on 4 May, completely destroying the transformer station and thereby reducing the rail line’s transport capacity by 50% for six months. Nevertheless, production at the mine was still 468,640 tons in 1942, only slightly down on the previous year. All three of the Norwegians escaped to Sweden.
