Is there any information in Hittite texts about the Trojan War?

While there is no direct information concerning the Trojan War in the Hittite texts, they refer to the battles between the Arzawa in the west and the Assuwa countries in the northeast during the reign of Great King Tudhalja II (1420-1400 B. C. E.) King Tudhalija starts a military expedition to the West and this ends with a victory for Arzawa country. However, there is an uprising right after the victory.

The rulers of the twenty two regions of the Assuwa country form an alliance against Tudhalija. Among the allies Wilusija and Taruisa that resembles the name Troy are mentioned. Tudhalija overcomes the Assuwa allies and puts all of Assuwa under their control. The Luwish scripture on the silver bowl that was published again in 2004, might be referring to this conflict. This scripture says that the silver bowl was ordered by Hittitean Asmaja for the king Mazakarhuha, on the year that the founding king Tudhalja won against Tarwiza king. In one of the related documents, a king who fought against Hittite allies named Attrasija from Ahhija is also mentioned. It is archeologically proven that, during these periods a Mycenaean attack also took place in Miletus (same as Milawanda in Hittitean texts) in Western Anatolia.

Two findings that were obtained in the Hittite capital Hattusa in 1400 B. C. E. indicate a conflict between the Mycenaeans and Hittites. The first one of these is the depiction of a Mycenaean type warrior on the Hittite plate; the second is the bronze sword of Mycenaean type. On the Akkadian writing on the sword, it says "When the Great King Tudhalja destroyed the Assuwa Country; he dedicated this sword to his lord, the god of storm." From this, we can conclude that the soldiers from Ahhijawa together with those from Assuwa fought against the Hittites. With this, we can think that the Mycenaeans who wanted to enter Anatolia first tried this via Millawanda, but when they were not successful, tried again a few generations later through Troy, and the Trojan War was a result of this second try.
