Musa's position after the defea was severely affected and he retired to Stefan, Serbia. He managed to gain the support of the Ottomans in Europe, and other followers of Süleyman approached him, some because of his promise, and some because Süleyman's unbalanced posture. His troops at the beginning of 1411 defeated Süleyman's defending troops in Serdica, while Süleyman himself escaped from Adrianople and tried to get to Constantinople. On this journey, he was captured and killed (17 February) by Musa's supporters, who then became the sole ruler of the European part of Ottoman Empire.
