'Heron Red' was a British operation by the Special Operations Executive to deliver a party (O. Baarnes, A.E. Telnes and A. Gundersen) by sea, re-establish radio contact with the earlier 'Heron' organisation and Lieutenant Sjøberg, deliver stores, and inspect and provide information on local groups (March 1943).
After the German infiltration of the 'Heron' organisation during the previous September, radio contact with the UK had been broken. The new team re-established contact on 7 April and Sjøberg was instructed to return to the UK. A Consolidated Catalina flying boat collected him at the beginning of May. Radio contact continued, but was broken between September and December 1943.
