Operation Crowfield

'Crowfield' was British operation by the Special Operations Executive to protect the Moholt transformer station and the Trondheim repeater station in German-occupied Norway, and to train and lead the local resistance groups recruited for these tasks (15 February/9 May 1945).

The operation began when B. Hasle and B. Lier were flown to Stockholm in neutral Sweden on 15 February. The group, now completed by A. Vibe, left for the border on 1 March but for various reasons had to abandon this first attempt to enter Norway. On 17 April, Hasle travelled via Oslo to Trondheim, arriving on 26 April. Vibe then left for Norway with another man, and radio contact was eventually established with Trondheim on 11 May. The targets were occupied on 9 May.
