March 18, 44 BC - Julius Caesar imposes a new army to be created. It is only meant to hunt down assassins and "betrayers." The first legion is sent out to find and kill the conspirators that attempted to kill Julius Caesar. Caesar's nephew, Octavian, is declared consul alongside his father.
42 BC - After settling tensions in the senate, Caesar returns attention to remaining barbarian tribes lurking in Gaul. Caesar launches a campaign to conquer Gaul and beyond. Meanwhile, his nephew, Octavian, decides to focus on moving eastwards toward Asia Minor. After discussing this with fellow senators, Octavian decides that Asia Minor must be fully explored before attacking. Training on a scout party begins on April 3.
40 BC - The scouting party returns to Rome with detailed topographical maps of much of Asia Minor, as well as the Levant. Roman engineers immediately begin planning the roads that will carry Roman forces deep into the interior of Asia Minor. Impressed by the scout's work, Octavian convinces the Senate to create a Roman Geographical Service, which creates detailed maps of the entire Roman Republic, as well as taking censuses of each province, so that the senate can be sure that each provincial governor is taxing the people of his province fairly.
37 BC - Julius Caesar's troops find and kill the last of the original conspirators in OTL Georgia. According to a later report back to Rome, one of the soldiers mentions a secret treaty with the Scythians, a people that inhabit OTL Southern Russia. Beforehand, the commanding officer of the troops makes haste to capture a nearby settlement, Tblisi. It is the main stronghold of the land of Armenia and the officer knows capturing this settlement will secure Rome's power in the Northeast and possibly open the gateway to Russia from the South.
Octavian also knows of the plan but hesitates to approve of the action. Tblisi is also a religious settlement, an icon of sorts, in this point of time. It is considered a holy place for peoples in the Levant, Mesopotamia, and Persia. Octavian fears that if the officer leads the attack and succeeds, Mesopotamia will be outraged and a storm of eastern barbarians will be burning Roman farms, villas, and most important: destroying roads. Since Rome already plans to build miles of roads into Asia Minor and possibly beyond, Octavian fears the efforts will be empty. Therefore, he convinces the officer to return to Rome to fight another day.
35 BC - Julius Caesar dispatches a large military force of 100,000+ men to lead into the area of OTL Antwerp, Belgium. Octavian is now resting from his "exploration-fest" in Asia Minor to focus on stability in Rome. The people are still shaken over what happened in 44 BC and are in danger of running riot, quite like France's Great Fear in the late 1700's. Octavian discusses new ways to calm the people and bring them back to their daily nonviolent lives.
