to be a military walkover. A further argument is that the panic which gripped Rome in 167–168 would make no sense if the Germanic tribes were still on the opposite side of the Danube. Also, no source mentions the emperor being near the front when the disaster occurred, whereas by 170 Marcus Aurelius had settled there. McLynn maintains that Marcus Aurelius and Lucius Verus went to Aquileia in 168 to restore morale after the disaster as Aquileia makes no geographical, logistical or military sense as a base of operations for launching a campaign on the Danube in Pannonia. The reason McLynn maintains that 170 is proposed by other authors is that too much weight is given to Lucian's testimony regarding the influence of Alexander of Abonoteichos as a scapegoat for the disaster whereas it is uncertain whether Alexander was still alive by 170 and Lucian's chronology is at certain points suspect. Deviating from the above discussion in English literature, researchers in Slovenia, one of the regions affected by the Germanic invasion, accept the year 168 as the proper date, based, among other arguments, on a portrait of Lucius Verus found in Ptuj. Roman counter-offensive and defeat of the Marcomanni This disaster forced Marcus to re-evaluate his priorities. Forces from the various frontiers were dispatched against Ballomar. They came under the command of Claudius Pompeianus, with the future emperor Pertinax as one of his lieutenants. A new military command, the praetentura Italiae et Alpium was established to safeguard the roads into Italy, and the Danubian fleet was strengthened. Aquileia was relieved, and by the end of 171, the invaders had been evicted from Roman territory. Intense diplomatic activity followed, as the Romans tried to win over various barbarian tribes in preparation for a crossing of the Danube. A peace treaty was signed with the Quadi and the Iazyges, while the tribes of the Hasdingi Vandals and the Lacringi became Roman allies. In 172, the Romans crossed the Danube into Marcomannic territory. Although few details are known, the Romans achieved success, subjugating the Marcomanni and their allies, the Varistae or Naristi and the Cotini. This fact is evident from the adoption of the title "Germanicus" by Marcus Aurelius, and the minting of coins with the inscription "Germania capta" ("subjugated Germania"). During this campaign, the chief of the Naristi was killed by the Roman General Marcus Valerius Maximianus. In 173, the Romans campaigned
