Lucius Verus
In 165, Roman forces, perhaps led by Martius Verus and the V Macedonica, moved on Mesopotamia. Edessa was re-occupied, Mannus re-installed.p169 His coinage resumed, too: 'Ma'nu the king' (Syriac: M'NW MLK') or Antonine dynasts on the obverse, and 'King Mannos, friend of Romans' (Greek: Basileus Mannos Philorōmaios) on the reverse. The Parthians retreated to Nisibis, but this too was besieged and captured. The Parthian army dispersed in the Tigris; their general Chosrhoes swam down the river and made his hideout in a cave. A second force, under Avidius Cassius and the III Gallica, moved down the Euphrates, and fought a major battle at Dura.p163
