Round 5: 680AD - 1040AD
I began the round by taking the suggestion of trading Philosophy to Bismark for Feudalism:
My feelings had leaned overwhelmingly for getting Machinery instead, especially since we're paying the same amount of gold (instead of less, as I had expected before trying). But the argument that Feudalism would make Civil Service cheaper won me over.
And the war against Rome continued. We whipped two catapults on the second turn and sent them to join our army at the front. Whether we'd head for Rome or Ravenna and Magyar, we could certainly use more of these WMDs. But our offensive had to wait. There were finally signs that the Romans were mounting a counterattack. First, two galleys were sighted heading in our direction:
When they were first seen, near Antium's Tip, I feared that it was heading for the end of our peninsula, where Hastings, defended by a single chariot with no hope of meaningful reinforcement, stood. Fortunately, the AI isn't so clever. Blinded by the overwhelming need to recapture his cities, Caesar landed his force near Neapolis.
It was small, but composed of effective units. And he landed it on a hill. Maybe the AI is not so hopeless after all. But, anyway, I sent two elephants from our stack to shadow the movement of the galleys, so we were able to defend the city. One of the catapults that were heading for the front hit the stack first to soften it a little. I promoted it with Drill to help ensure that it would score hits against the longbowman. Then our elephants moved in. We were quite lucky - one of them won at rather low odds (30+%). And the others weren't unlucky, so we only lost that one catapult in the battle.
The successful defense spawned our first GG:
As I almost always prefer it, he was attached to a chariot to be a Medic III unit. However, this time, the chariot had Medic I already (promoted after it got lucky and killed a crossbow at low odds near Nottingham, before the latter could pillage our copper), so there was enough xp for a spare promotion after Medic III (also thanks to Charismatic). I gave it Morale for the extra movement. Now we have a super medic that can zip to anywhere he's needed in no time
There was more good news a few turns later; a rather big thing, in fact. Iron was discovered in a mine near Nottingham:

That meant, at least, that there's no necessity to take either Ravenna or Magyar in this war and we could bide our time to attack Rome itself.
However, Caesar wasn't going to give us an easy time. The galley-borne stack and the pillaging crossbow weren't the only Roman units to enter our territory. Elsewhere, a few Praetorians and macemen began making their appearance and had to be dealt with by Shock elephants, often not without cost. Because of this, we had to keep building elephants, especially in our productive capital, and couldn't risk the anarchy from switching to Bureaucracy when CS was discovered. Eventually, both our copper and iron mines were pillaged. We even lost a worker to a Woodsman II maceman that cleverly used a forested hill to run in and capture him. But we managed to destroy every attacker, and once we added more catapults to our stack, it began to move against Rome itself.
We had built a trireme in Hastings, which I had meant to send to Rome to scout its defenses out, but a Roman trireme blocked the way (couldn't travel on the ocean to sail around) so it couldn't get there. Because of this, we could only send our stack there blindly and hope that Caesar didn't have too many units.
We made another trade with Bismark after getting CS:
The Romans already had it, so it wouldn't be long before the Germans get it too. I considered using the same gambit of partially researching Machinery and then trading for it, but I decided not to take the risk this time. Bismark could get CS anytime. These techs we were getting are quite important anyway, and the gold was nice and would help us research Machinery ourselves.
Then, just as we began the Siege of Rome, we managed to score another hit:
Elephant vs. a longbow in a new city gives pretty good odds of winning. We kept the city, of course.
Then, hitting Rome with all the might of our catapults, three of which survived, we captured it:
Again, we were quite lucky and lost few units. The city wasn't very heavily defended, but it had at least two longbows, a crossbow and a praetorian. Yes, there's another city to east, though, which would put annoying cultural pressure on Rome unless we got rid of it.
Anyway, here's what we found in Rome:
Good stuff! The forge and the Academy were true jewels. However, for the city to truly shine, we would have to take and raze the Roman city to its east. The latter was on a hill, though, so it might be a problem, especially since we didn't have many catapults left after Rome.
