The scene changes to the banks of the river, as in Act I. The army is ready for war. Telramund’s dead body is carried in. The Knight explains why he killed Telramund. He tells the story of the Holy Grail and says that he is Lohengrin, Knight of the Holy Grail and son of King Parsifal. He says that he now has to return to his home. He had only stayed so long so that he could prove that Elsa was innocent.
