Beffort Gap

The Beffort Gap is the term used to describe the German militarily-fortified area of land in Southwestern France built to repulse the Allied advance into Germany during the later stages of World War II. The 'gap' was successfully broken on 20 November 1944 by French military forces which brought the allied efforts to the banks of the Rhine.
