The Channel Islands were occupied by Germany in June 1940 and were the only part of the United Kingdom invaded during the war. Although little active resistance occurred, a number of underground publications existed. The most notable was the "Guernsey Underground News Sheet", or GUNS, on Guernsey. The newspaper, directed by Frank Falla and published between 1942 and 1944, reproduced material from BBC news bulletins. Its workers were denounced in February 1944 and deported to concentration camps.
