The Third Battle of Tiamat continues. The 11th Fleet under Willem Holland dominates the battlefield for a few hours with its wild "pioneer-like" tactics. However, just as it reaches its limit of expansion, Reinhard von Müsel orders his fleet to conduct a long range pinpoint attack against the heart of the 11th Fleet and succeeds in destroying a significant number of ships, including Holland's flagship Epimetheus. With the loss of its commander, the 11th Fleet is quickly routed by the other Imperial fleets. Further damage is minimised though with the timely intervention of the 5th Fleet and 10th Fleet, who cover the retreat of the surviving ships from the 11th Fleet before withdrawing completely from Tiamat Starzone.

For his efforts in the Third Battle of Tiamat, Reinhard is promoted to the rank of Admiral and is granted a couple of honorary positions. However, none of these positions delights Reinhard more than the bestowal of a personal flagship, the experimental battleship Brünhild, to him.
