The Parthians are moving fast, and if we leave them alone, we will be endlessly chasing them over the whole theater. So, despite being slightly weakened by the two fights at Zenodotia, Caesar orders a dash to Nisibis, a key and well fortified city that controls the northern Mesopotamia foothills and can prove a wonderful base for further campaigning
In the meanwhile, Vatia and prince Kastor’s Galatians will continue besieging Tigranocerta (southwest of Nisibis) and wait till breaches are made.
We expect the Parthians to run off and lick their wounds, which would be the sound thing to do.
Caesar’s speed and talent (in particular the “Assaulter” ability which allows him to launch assaults even if no breaches are made) do wonders at Nisibis: the Parthians were unsuspecting and the cities falls in a brief and bloody assault for the defenders (the losses among the legionaries look relatively small in comparison, thanks also to our vast superiority in archers that have softened the defense right before the walls were scaled).
This is the best news we could expect, as the large walled city can now serve as a supply base for our future offensive down the Tigris.
In the meantime, the Parthian prince Pacorus has led a foray into Armenia, which was repulsed by the Armenian King Tigranes. The Parthians have made a mistake, since their incursion has released the strong Armenian forces before their time (they were still ‘locked’ for the next 9 months). We are certain to punish them for it.
Caesar has decided that, because of the light losses at Nisibis, and despite a supply situation that is starting to be worrisome, it would be great to catch the retreating Parthians before they can get out of reach. Here, two of Caesar’s other exceptional abilities come into play. Caesar's master spy network allows him better information on the theater, and we have discovered that the King of Kings has taken shelter in the city of Singara, just less than a month of marching southeast of Nisibis (where they were probably not expecting us!). Second, as a Logistics Expert, Caesar is much better at living off the land (25% supply bonus) and can therefore be less worried about supply.
So we shall make another risky decision: let’s rush without rest down to Singara and besiege the whole Parthian force when they expect to quietly recover their supplies inside the city. The region is steppe-land and could pose a danger if we were caught by Parthian cavalry in the open, but we are gambling that they will need to recover their loss of strength and cohesion inside their walls, and not be in a position to attack when we arrive there.
Caesar remains very active also and decides to plan for a major siege and battle at Singara.
It is necessary to increase military control in the region to ensure a proper siege of the Parthians, reducing their logistical status while improving the Roman one. Playing the “Punish” RGD will just do that, as even if the local loyalty suffers (who cares, the Legions are almighty!), the control increases drastically.
In addition, orders are given to the whole army to go on a strict defensive. This can help defeat the Parthians if they go out of the city to break away.
In the meanwhile, the forces of Aulus Alienus will move from the banks of the Euphrates and try to catch the remaining Osrhoenian allies of our enemies still wandering on the northern bank.
Turn execution is again surprising and the gods are still with us (Caesar is the darling of Venus). In the north, the Armenians are on the move and catch Pacorus, defeating him but not decisively and suffering a few losses.
Aulus Alienus is also successful and destroys the remaining Osrhoenian forces in the field.
Caesar was right -- our enemy tried to sortie, but our tactical position helped defeat them.
another magnificent jewel to the roman crown (and his!) and getting ready, may be, to follow Alexander’s footsteps into Sogdiana, the Indus valley, may be India and who knows, to China and beyond. Julius Caesar would this surpass his model and become the greatest conqueror of all times!
Author’s Notes: I've tried to write this AAR in the spirit of Caesar’s “De Bello Gallico” (The Gallic Wars), with the author writing about himself in the third person and not forgetting to display proudly his great feats! A wonderful historical and propaganda masterpiece.
