The region of "al_bosayre" is about 104 kilometers away  from Deir ez-Zor and is close to the common borders of Iraq and Syria, and is most likely the same area in the narrations of the Ahl al-Bayt (as)   The Battle of Gherghisia will take place in the present-day Deir ez-Zor region, specifically at the mouth of the Khabur River and at the confluence of the Euphrates River. The source of the Khabur River is in Turkey, and after flowing into the country, it enters Syria and flows into the Euphrates River, which today is called "Basira", which is a small village, but throughout history the name of this region has been "gherghisiaa"  The first intersection of the armies moving from the north to the gherghisiaa is the "island" area in the south of Deir ez-Zor province. The opposite point of the "island" is the "Abu Kamal" region in Syria and the "Al-Qaim" region in the Anbar province of Iraq. Mashregh News
