According to Wikipedia, "Holger Danske" was a Danish resistance group during World War II. It was created by veteran volunteers from the Winter War who had fought on the Finnish side against the Soviet Union. But there's more, "Holger Danske" was a legendary Danish heroe. I believe that the song is about a war. (Sorry for my English, it's not very good).
