Tryggvi the Pretender

[3][4] Svein and his forces made their way south to Agder, believing that Tryggvi would attempt to slip through the Skagerrak and join his supporters in Viken.

[3] During the battle, according to reports recorded by Snorri, Tryggvi hurled javelins at his enemies with both hands simultaneously, a feat for which Olaf Tryggvason had been known.

After questioning the purported killer and hearing him confess, King Harald had the man hanged, citing the familial bond between him and Tryggvi and his duty to avenge the latter's death.

Excerpts of the poem, usually attributed to Canute's court poet Sighvat Thordarson, were preserved in Heimskringla: For fame eager, forth fared from the north King Tryggvi, whilst Sveinn from the south forth sailed to join the battle From fray not far was I.

[7] Another poem recorded in Heimskringla, by an unknown skald, mentions the battle against Tryggvi: That Sunday morning, maiden, much unlike it was to days when at wassail women wait on men with ale-drink when Sveinn the sailors bade his sloops of war to fasten by their bows, with carrion battening hungry ravens.
