Expedition to Samosata

The Expedition to Samosata was undertaken by Baldwin I of Jerusalem following his ascension to co-regent of Edessa as a part of the First Crusade. His main goal was to eliminate the Emirate of Samosata as a commercial and military rival of the Edessene state. The expedition was carried out from 14 to 20 February, 1098.

Circumstances of the War
Baldwin decided upon his ascension of co-regent of Edessa that Samosata would have to be eliminated in order for his new county to fully control the surrounding countryside and to establish unbroken communications with Byzantium in the west and the crusaders sieging Antioch in the south. The Armenian, Christian inhabitants of Edessa enthusiastically supported his plan, and the main part of their military accompanied him. He set out on 14 February, also accompanied by an Armenian princeling, Constantine of Gargar.

The Conflict
Despite the help of the Edessene militia, the expedition was not to turn out favorably for Baldwin. The Edessenes were poor, inexperienced soldiers, and the company was quickly caught in an ambush by the Turks of Samosata, who slew around a thousand of them in the ensuing battle. Baldwin, however, did manage to capture and garrison the village of St. John, which was close to Balduk's capital. From this point, he was able to control the flow of the Turks in and out of the city, resulting in a decline in Turkish raids into the Edessene countryside.
