A monument in Vrba, Austrian Carinthia, with the ingraving: “The Serbian cavalry came this far and went no further, 1919”. This is a memorial dedicated to the Austrian troops who stopped by the Serbian invaders.
When the Habsburg Monarchy collapsed in 1918, there was a border dispute in Carinthia. Slovenian and Yugoslav forces entered the area where Slovenes lived, while German/Austrian forces wanted to maintain control. This led to armed clashes in 1918–1919.
Local German-Austrian authorities later erected memorials and inscriptions for having repelled the invading Yugoslav-Serb troops, part of the post-war national memory in Carinthia.
The Carinthian plebiscite of 1920
The formal border issue was later settled through negotiations and a referendum (the Carinthian plebiscite of 1920) in which large parts of Carinthia chose to belong to Austria. It is therefore not uncommon for villages to mark the “border” of enemy advance with a sculpture or text dated 1919.
