The Battle of Laupen was fought on June 21, 1339 between the Bern and its allies on one side, and Freiburg together with feudal landholders from the County of Burgundy and Habsburg territories on the other. Bern was victorious, consolidating its position in the region. As a consequence of the conflict, the relations of Bern and the Swiss Confederacy tightened, resulting in Bern's permanent accession in 1353. This is also the first battle that the white cross was documented as being used as a field sign worn by Swiss combatants.
