This is a chapter from *Teutonic Myth and Legend* (1912) by Donald A. Mackenzie, a work of mythological scholarship retelling Germanic heroic legend in narrative prose form. The chapter covers the exile and campaigns of Dietrich of Bern (the legendary version of Theodoric the Great), tracing how the evil counselor Sibeche manipulates King Ermenrich into destroying his own sons, the Harlung kinsmen, and finally driving Dietrich from his kingdom by holding his captured knights hostage. Dietrich surrenders his realm to ransom his men, takes refuge at the court of Attila the Hun (Etzel), and eventually mounts a military campaign to reclaim his kingdom — a campaign that ends in pyrrhic triumph: his forces win the battle at Ravenna, but his brother Diether and Etzel's two young sons are killed by the knight Witege, who then escapes into a lake where a mermaid ancestor pulls him beneath the waves. The chapter draws on the Old Norse and Middle High German heroic tradition (the *Thidrekssaga*, the *Nibelungenlied* cycle) and presents these stories in accessible, novelistic form aimed at a popular English-speaking audience. Its most distinctive element is the tragic moral symmetry: Dietrich wins every fight and loses everything that matters, and the chapter ends on the theme of loyal grief and enduring friendship between him and Etzel rather than triumphant reconquest.
