'Sanderling' was a British operation by the Special Operations Executive to deliver a party to work in the counties of East and West Agder in the southern part of German-occupied Norway with the 'Sandpiper' party (September 1944/May 1945).
The four-man party, comprising K. Austad, T. Andersen, H. P. Armstrong, L. Eide, was parachuted into the country to reinforce the 'Sandpiper' team. Austad and Eide worked in the area around Kristiansand. Preparations were made to receive operation 'Varg I', but the party’s activities were badly affected by German raids and organisation proved difficult. Supplies also remained short, and it was March 1945 before airdrops eased the situation and some training could be started.
