I hope this would be right translation for Lāčplēsis. It is national epic written by  Andrejs Pumpurs between 1872 and 1887 based on local legends. Lāčplēsis is national hero who defends his homeland from assorted invaders. More about Lāčplēsis look in wikipedia.
On November 11 we celebrate Lāčplēsis day - we commemorate the victory over the bermontians at the battle of Riga on 1919. Fantastic historical view is here.
