In the Great War of 1914-1918, some 30,000 men from South Jutland (North Schleswig) were drafted into service in the German army. 5,333 of them fell. They lie buried in German war cemeteries on many different fronts, but especially on the West Front. After the reunification of South Jutland with Denmark in 1920, the idea arose of establishing a special cemetery, to which the Danish-minded among the fallen might be transferred if their families so wished.

The Cemetry in Braine was established in 1924, and contained the remains of 50 soldiers reburied there – a number that has since increased to79. Despite the fact that only a few soldiers are buried here, this cemetery has become a memorial for all the fallen from South Jutland, both Danish-minded and German-minded. In 2013, memorial plaques have been set up, recording the names of the fallen according to their parish.

The web site www.museum-sonderjylland.dk/sonderborg has records containing detailed information about the South Jutlanders who fell in the war.
