Battling sources

Here is all I can find vtsaogames...

Gordian III (https://en.wikipedia.org/wiki/Gordian_III )
In 241, Gordian was married to Furia Sabinia Tranquillina, daughter of the newly appointed
praetorian prefect, Timesitheus. As chief of the Praetorian Guard and father in law of the Emperor,
Timesitheus quickly became the de facto ruler of the Roman Empire.
Persians under Shapur I invaded Mesopotamia, and the young emperor and sent a large army East.
The Sassanidswere driven back over the Euphrates and defeated in the Battle of Resaena (243).[1]
The campaign was a success and Gordian, who had joined the army, was planning an invasion of the
enemy's territory, when his father-in-law died in unclear circumstances. Without Timesitheus, the
campaign, and the Emperor's security, were at risk.
Gaius Julius Priscus and, later on, his own brother Marcus Julius Philippus, also known as Philip the Arab,
stepped in at this moment as the new Praetorian Prefects[2] and the campaign proceeded.
Around February 244, the Persians fought back fiercely to halt the Roman advance to Ctesiphon.
Persian sources claim that a battle occurred (Battle of Misiche) near modern Fallujah (Iraq) and resulted
in a major Roman defeat and the death of Gordian III.[3] Roman sources do not mention this battle and
suggest that Gordian died far away from Misiche, at Zaitha (Qalat es Salihiyah) in northern Mesopotamia.
Modern scholarship does not unanimously accept this course of the events. One view holds that Gordian
died at Zaitha, murdered by his frustrated army, while the role of Philip is unknown.[4] Other scholars,
such as Kettenhofen, Hartman and Winter have concluded that Gordian died in battle against the Sasanians.

Shapur I (from en.wikipedia.org/wiki/Shapur_I )
Ardashir I had, towards the end of his reign, renewed the war against the Roman Empire, and Shapur I
had conquered the Mesopotamian fortresses Nisibis and Carrhae and had advanced into Syria. In 242,
the Romans under the father-in-law of their child-emperor Gordian III set out against the Sasanians with
"a huge army and great quantity of gold," (according to a Sasanian rock relief) and wintered in Antioch,
while Shapur was occupied with subduing Gilan, Khorasan, and Sistan.[13] There the Roman general
Timesitheus fought against the Sasanians and won repeated battles, and recaptured Carrhae and Nisibis,
and at last routed a Sasanian army at Resaena, forcing the Persians to restore all occupied cities unharmed
to their citizens. “We have penetrated as far as Nisibis, and shall even get to Ctesiphon," the young emperor
Gordian III, who had joined his father-in-law Timesitheus, exultantly wrote to the Senate.
The Romans later invaded eastern Mesopotamia but faced tough resistance from Shapur I returned from the East.
Timesitheus died under uncertain circumstances and was succeeded by Philip the Arab. The young emperor Gordian III
went to the Battle of Misiche and was either killed in the battle or murdered by the Romans after the defeat. The Romans
then chose Philip the Arab as Emperor. Philip was not willing to repeat the mistakes of previous claimants, and was aware
that he had to return to Rome to secure his position with the Senate. Philip concluded a peace with Shapur I in 244; he had
agreed that Armenia lay within Persia's sphere of influence. He also had to pay an enormous indemnity to the Persians of
500,000 gold denarii.[14] Philip immediately issued coins proclaiming that he had made peace with the Persians (pax fundata
cum Persis).[15] However, Philip later broke the treaty and seized lost territory.[14]
Shapur I commemorated this victory on several rock relief’s in Pars.
