I was stationed not to far from where this battle supposedly took place.
Okay, we are drifting back slowly into my knowledge base now:
During Trajan's time, around 116 AD, the Roman general Lucius Quietus sacked Edessa and put an end to Osrhoene's independence. After the war with Parthians under Marcus Aurelius, forts were built and a Roman garrison was stationed in Nisibis. Osrhoene attempted to throw off the Roman yoke, however in 216, its king Abgar IX[clarification needed] was imprisoned and exiled to Rome and the region became a Roman province. In the period from Trajan's conquest (116) to 216, Christianity began to spread in Edessa. Abgar IX (179-186 AD) was the first Christian King of Edessa. It is believed that the Gospel of Thomas emanated from Edessa around 140 AD. Prominent early Christian figures have lived in and emerged from this region such as Tatian the Assyrian who came to Edessa from Hadiab (Adiabene). He made a trip to Rome and returned to Edessa around 172-173. He had controversial opinions, seceded from the Church, denounced marriage as defilement and maintained that the flesh of Christ was imaginary. He composed Diatessaron or "harmony of the Gospels"(Ewangelion da-mhalte) in Syriac, which contained eclectic ideas from Jewish-Christian and dualistic traditions. This became the Gospel par excellence of Syriac-speaking Christianity until in the 5th century Rabbula, bishop of Edessa, suppressed it and substituted a revision of the Old Syriac Canonical Gospels (Ewangelion da-mfarshe).[15]
After this, Edessa was again brought under Roman control by Decius and it was made a center of Roman operations against the Persian Sassanids. Amru, possibly a descendant of Abgar, is mentioned as king in the Paikuli inscription, recording the victory of Narseh in the Sassanid civil war of 293. Historians identify this Amru as Amru ibn Adi, the fourth king of the Lakhmid dynasty which was at that time still based in Harran, not yet moved to Hirah in Babylonia.[16]
Many centuries later, Dagalaiphus and Secundinus duke of Osrhoene, accompanied Julian in his war against the Sassanid king Shapur II in the 4th century.[17]
In his writings Pliny refers to the natives of Osroene and Commagene as Arabs and the region as Arabia.[18] According to Pliny, a nomadic Arab tribe called Orrhoei occupied Edessa about 130 BC.[19] Orrhoei founded a small state ruled by their chieftains with the title of kings and the district was called after them Orrhoene. This name eventually changed into Osroene, in assimilation to the Parthian name Osroes or Chosroes (Khosrau).[20]

He is buried there in a Cenotaph? It was turned into a launching point for operations under Decius?
