[Anna Komnene gives two versions of the death of Tutush, while Bozan resurfaces in the story of the death of Abul-Kasim, which seems to be dated later than Bozan's death. These events are very unsure in her text.] After Tutush had sent Assassins to murder Malik-Shah, Bozan was withdrawing to Chorasan, when he met the murderer Tutush himself. A great and hard-fought battle ensued; eventually Bozan was defeated and killed and his forces scattered. The victorious Tutush felt himself already sultan - but in fact was in great danger. He was killed in another great battle by Barkiyaruq, the son of the murdered Malik-Shah, who totally defeated him. Another story has Tutush killed in revenge by cousins of Bozan
