 This identification was first put forth by Emil Forrer, but largely disputed by most Hittite experts until 1983 when Houwink ten Cate showed that two fragments were from the same original cuneiform tablet and in his discussion of the restored letter showed that "Taruiša" and "Wiluša" (Troy) were correctly placed in northwestern Anatolia.According to Trevor Bryce, Hittite texts indicate a number of Ahhiyawan raids on Wilusa during the 13th century BC, which may have resulted in the overthrow of king Walmu.Bryce also said that archeological surveys conducted by John Bintliff in the 1970s showed that a powerful kingdom that held sway over northwestern Anatolia was based at Wilusa (Troy).
