Bjarne Keyser Barth

Bjarne Keyser Barth (14 April 1892 – 23 April 1972) was a Norwegian military officer in the Norwegian fortress artillery. A military officer from 1914, Barth took part in Norwegian neutrality protection duties during the First World War, mostly at Oscarsborg Fortress. Remaining in military service after the end of the First World War, he served at several different Norwegian fortresses, finally at Fossumstrøket Fortress in south-eastern Norway.

In the inter-war years, Barth continued his military career, as well as working as a journalist, schoolteacher and book editor, and ran a small business.

During the Second World War, Barth again took part in neutrality protection duties, until the German invasion of Norway in April 1940. Barth led the garrison of Høytorp Fort, which fought the German invasion forces before being encircled and surrendering. In 1942, Barth was arrested by the occupying German forces and sent as a prisoner of war to Germany.

In the post-war years, Barth was involved with officer associations, and edited several military professional magazines. In this role he was often critical of the political leadership of the Norwegian Armed Forces.
