The annals of Mursili II record that in the 3rd year of his reign, which would be 7 years prior to Mursili's eclipse in 1312 BC, prince Piyama-Kurunta of Arzawa stood against his army at Walma by the river Astarpa.
The following winter, Mursili withdrew to the Astarpa to prepare for the next season.
The annals of Mursili during the Astarpa campaign mention nearby regions of "Apasa", "Millawanda", and "Ahhiyawa".
It is thought that these are the Bronze Age names of Ephesus, Miletus, and Mycenaean Greece.
