All is quite for a few years, but then:
Autumn 127: The Parthians arrive back in Bactria. This time it looks as though they are going to stay. The Indians across the eastern border of Bactria decide not to provoke any aggressive moves from the men on horses, and so prudently move southwards back towards their own supply bases. They will want to confront the Parthians later, on their own terms.
Summer 126: The Indians arrive in Sattagydia, to link up with reinforcements.
Spring 125: The Ligurian Revolt. Just to compound Rome's problems, the Latin city of Fregellae also rebels. First stirrings of unrest amongst the Socii?
Summer 125: The Roman army that put down the Slave Revolt in Sicily marches back northwards and reaches Campania.
Autumn 125: Fregellae falls swiftly to a surprise assault as a Roman citizen secretly opens the gates from within. The town is levelled. The Roman army then moves on into Etruria.
Spring 124: The Romans assault Liguria.
