First skirmish over Sunrise

A skirmish occurred above the planet nicknamed "Sunrise" between the Chiss Expansionary Defense Fleet and forces allied with the Grysks, in approximately 18 BBY.

During the skirmish, the Springhawk was attacked by three formations of five missile boats. Soon thereafter, the Grayshrike, commanded by Senior Captain Irizi'in'daro, arrived in the system to deliver a message from Admiral Ar'alani to Senior Captain Mitth'raw'nuruodo. Lakinda ordered her Grayshrike to join the battle to protect the Springhawk.

During the battle, the Springhawk and Grayshrike were attacked by the HopeBreaker apparently accompanied by a repair ship which turned out to be a freighter. The Battle Dreadnought kept the Chiss forces occupied while the freighter escaped to hyperspace. Thrawn disabled or destroyed all of the missile boats as well as the armaments and sensors on the Battle Dreadnought's port side. After the freighter escaped into hyperspace, the Battle Dreadnought also fled, but first destroyed all the intact missile boats so the Chiss could not learn anything about their design or schematics.
