Mursili II
Furthermore, Mursili II talks of stopping in Samuha on his way home from the Kaska lands in his Ten Year Annals (KBo 34 iii 45), which would argue strongly against a location on or near the Euphrates. Gurney and Garstang (1959, pp. 35ff) provide a more extended discussion about how Hittite documents seem to contradict a location for Samuha along the Euphrates, locating it instead along the Kizilirmak near modern Sivas, perhaps at Zara.
