|Concurrent||Battle of Untema|
The Battle of Iexiu (May 2 to 18, 2010 — 16 days) was a major battle of the second Appearance-Ichiri war between the Empire of Drakonia, supported by the Yulairian Civilization, and Ichiri. It saw relatively long-term deployment of space fleets, some groups even fighting for the duration of the 16-day battle, but inevitably ended in the Ichiri forces retreating due to their resources being strained. It was the first time the Empire of Drakonia had been assisted by another nation in the war, and, much later on, also saw the first deployment of the main Drakonian battle forces inside the Appearence galaxy on a small scale from May 4 and on a large scale from May 16.
The strike was the third of six initial strikes in the Drakonian colonial front of the war, and involved the largest amount of combined Ichiri forces in the whole front: Of the 17 strike forces which spearheaded the Drakonian front, six were used to attack on this planet alone.
