From: The History of Rome, by Theodor Mommsen
Translated with the sanction of the author by William Purdie Dickson
The disbanding of the bravest and most turbulent legions and the recall of the commander-in-chief, in connection with the impression produced by the defeat of Ziela, dissolved all the bonds of authority in the army just when the general had most urgent need of their aid. Near Talaura in Lesser Armenia he confronted the Pontic troops, at whose head Tigranes' son-in-law, Mithradates of Media, had already engaged the Romans successfully in a cavalry conflict; the main force of the great-king was advancing to the same point from Armenia.
Lucullus sent to Quintus Marcius the new governor of Cilicia, who had just arrived on the way to his province with three legions in Lycaonia, to obtain help from him; Marcius declared that his soldiers refused to march to Armenia. He sent to Glabrio with the request that he would take up the supreme command committed to him by the people; Glabrio showed still less inclination to undertake this task, which had now become so difficult and hazardous. Lucullus, compelled to retain the command, with the view of not being obliged to fight at Talaura against the Armenian and the Pontic armies conjoined, ordered a movement against the advancing Armenians.
