obligations included both timely intelligence about potential anti-Hittite activity as well as soldiers for military expeditions. Some evidence suggests that Muwatalli invoked this later obligation, as Wilusan soldiers appear to have served in the Hittite army during the Battle of Kadesh. At some point during Muwatalli's reign, he had to send an army to reassert Hittite control over Wilusa. The exact circumstances of this event are unclear, since it is only known from a brief mention in the poorly preserved Manapa-Tarhunta letter. One hypothesis suggests that the ruler of Wilusa had been deposed by Piyamaradu, a local warlord who toppled other pro-Hittite rulers in the area while acting on behalf the Ahhiyawa. This interpretation finds potential support in the later Tawagalawa letter which alludes to a previous disagreement between the Hittites and Ahhiyawa concerning Wilusa. However, this evidence is not conclusive since the Tawagalawa letter does not specify whether the disagreement escalated beyond strongly worded cuneiform tablets, and the Manapa-Tarhunta letter does not directly connect Piyamaradu to the trouble in Wilusa. Evidence against this interpretation includes a section divider in the Manapa-Tarhunta letter which seems to suggest that Piyamaradu's activities and the Wilusa event were separate topics. Thus, there is no scholarly consensus as to whether the king of Wilusa was deposed by Piyamaradu, by an internal uprising, or remained in power while rebelling against the Hittites. The final reference to Wilusa in the historical record appears in the Milawata letter, sent by the Hittite king Tudhaliya IV to one of his key vassals in western Anatolia, likely the king of Mira. Tudhaliya's letter requests that the recipient send him Walmu, the recently deposed pro-Hittite king of Wilusa, whom he intends to reinstall. The letter promises that although Walmu will be the ruler of Wilusa, the recipient will maintain ultimate authority over the various kingdoms in the region. The letter does not specify how Walmu was deposed, though its discussion of the geopolitical situation in western Anatolia makes clear that the Ahhiyawa were no longer a major power. In popular writing, these anecdotes have been interpreted as evidence for an historical kernel in myths of the Trojan War. However, scholars have not found historical evidence for any particular event from the legends, and the Hittite documents do not suggest that Wilusa-Troy was ever attacked by Greeks-Ahhiyawa themselves. Noted Hittiteologist Trevor Bryce cautions that our current understanding of Wilusa's history does
