The Battle of Lyrasia lasted from 25 to 28 of Sun's Dawn, 138 BTW. On 28 of Sun's Dawn, the invading army of Tiberius abandoned the siege because of casualties sustained during an engagement with his brother, Jasyn, and retreated north. The Battle was the only major engagement during the Dalunian Civil War, since both brothers who aspired for the throne's armies were defeated which forced them to flee and found their own nations.
