  ABSTRACT: In previous articles dedicated to various German military structures of the Atlantic Wall in West Brittany, the preservation state and the organization of their components have been analyzed. The components have generally been found in a good preservation state without damages due to combats or bombardments. This is not the case of the components of the German coastal artillery battery HKB1274/StP C342 described in this article. The article shows also the organization of the battery, how it integrated pre-existing French military structures and how a massive allied air bombardment affected it.
