Augustus and Agrippa would continue to be successful in their military pursuits.
His successful military pursuits would help Augustuspopularity and continue to give him legitimacy as sole ruler of Rome
Military success would also lead to a period of expansion for the empire and the period known as the Pax Augusta
After Actium, Augustus campaigned until 29 BCE.
Although Antony and Cleopatra were dead the civil war continued for a few years, fighting in Dalmatia and Alexxandria.
When he finally returned to Rome he celebrated a 'Triple Triumph'. This was also recorded in Augustan propaganda in a triumphal arch and also in coinage with the Denarius of Augustus, Capture of Egypt Denarius and Capture of Armenia aureus.
His militaristic presentation declined during his reign as he sought to distance himself from his younger self, who won power through spilling the blood of other Romans.
In the Res Gestae, Augustus tells us he would extend the frontiers of the empire from Hispania, Syria, Judea and the Rhine.
Beyond the frontier he would establish Armenia as a client kingdom and maintain good relations with the powerful state of Parthia.
He also closed the doors of the Temple of Janus indicating that the empire was at peace, ushering in the Pax Augusta.
The Varus disaster (9CE, Germania) was the one blow on Augustus' military record.
This was were a German called Arminius, who was a Roman ward, destroyed the legions at the Battle of Teutoburg Forest.
Augustus wanted to protect the province of Gaul from Germans from across the Rhine by extending the frontier as far as the Elbe river.
He was initially successful with his stepsons Drusus who was killed, then Tiberius supressing the tribes.
Varus was given command of Germania.
Varus harsh treatment of the local population led to an attack in Teutoburg forest.
20,000 troops where wiped out and Varus committed suicide.
After the Varus disaster Augustus would be much more defensive his policy and consolidate rather than expand the empire.
