1951 AD - Just because I feel like it, I make attacking a poor Persian galley with a Destroyer my first move of this turn.
And then we sink a Frigate with a Cruiser. I love having by far the most modern navy

.
Of course, the true battles this turn will take place on land. We will begin at the mouth of the Nile with Ajax attacking Alesia. Though a more risky move than a Kolokotronin attack, the potential rewards are greater - a full-strength army to hammer Entremont.
The first battle goes decently well, leaving Theodoros with five hitpoints and the Celts with a Conscript Infantry. The odds are in our favor, so we roll the dice.
Again we win, but the Celts have another conscript. We roll again.
And the city is ours. One must take risks to get rewards, and this one paid off handsomely. Alesia already has 22 shields of production, and will be a strong contendor for the Iron Works.
It occurs to me at this point that all three cities we are targeting are capitals. Thus we shall seek a triumverate of palacial victories this turn; a veritable triple play in taking down our enemies' centers of power.
Antium will be attacked first, as it is by far the easiest target. Two Artillery pound the city, and then the Elite Tanks roll in.
The second tank to attack gets redlined, but we take the city. And the first tank made the Musketmen look really pitiful.
Now it is time to take the city we have longed to take for nearly a hundred years.
Tenochtitlan.
Oh yes, we do bombard it as much as we can. And then we send the world's first Mechanized Infantry division at the city.
And it loses. Rubbish.
But we will not surrender. Tenochititlan must and will be taken, for the honor of Greece!

"They always bombard the city, and never attack. Don't worry," Montezuma had said hours before. He had been proven wrong already, but had thus far refused to evacuate.
"Do you value your head?" he asked his general. "The Ottomans attack with the most highly regarded cavalry in the world, and are always turned back. The Greeks attacked with the most advanced weapons on Earth, and failed. You mean to tell me you think some regular Greek rabble can overthrow the finest city in the world?"
"Your honour, they did take Teotihuacan..."
(Montezuma nods, and the guards draw swords to the general's neck)
"...but of course they do not stand a chance at taking Tenochtitlan," the general finished, hoping this would save his life.
"Correct you are," replied Montezuma. "Now, command them like a general. We shall win - Quetzalcoatl wills it."
But the general had reason to be concerned. His first guard corps fell quickily, and the Greeks then sent in more troops. Before long, the last Aztec defenders were overwhelmed by the Greek Infantry. It was only at the last second Montezuma was persuaded to leave.
"No, I will not leave. The palace guards surely will hold off the Greeks. Tenochititlan is invincible," Montezuma said. An artillery shell then crashed through the palace, killing two of his palace guards before his eyes. The sounds of warfare had been growing progressively louder from outside for several hours.
"Your honor, we must acknowledge the facts. If their infantry don't take the palace, their artillery will tear it to shreds and we'll be forced to evacuate anyways," said his personal advisor. "The rest of the royal family is already in the train ready to leave for the port, and the passage to the railroad station is as well-guarded as possible in the present circumstances. I urge you, acknowledge the danger and leave."
Montezuma thought and then replied, "Very well. It is better to evacuate and rule from another palace than to hide and cower in the streets. We shall leave."
The Royal Guard guided Monztezuma safely to the rail station, despite the shells still falling on the city, and within minutes the great steam engine roared to life. Slowly it accelerated, then more quickly. Danger, however, still lurked. An alert Greek commander had realized the escape route, and send a group of soldiers to intercept the train. They were only just nearing the track when the train approached, and knew they would not have a chance to sever the track and Aztec escape. Thus, they set up machine guns instead. If they couldn't take it out one way, perhaps another way would succeed.
The Aztecs on the train saw the Greek machine gun contingent, but already traveling dozens of miles per hour, there was no way they could stop the mighty train. They would have to face the bullets. So they did the only thing they could and accelerated to minimize the bullets they would inevitably face.
"Inconceivable," said Montezuma.
"We're just fortunate the track appears to be intact, sir," replied the head of the Royal Guards. "But there is nothing we can do now to avoid the ambush. I must recommend, however, that you quickly move to the safety offered by the engine."
"Whoever was the genius who came up with this escape route?" Montezuma grumbled. This wasn't the supreme power he was used to. But he agreed that it was better to survive in the steel engine, even if it be covered in coal and dust, than to risk his life by staying in his palacial coach. Thus he headed forward in the train with his finest guard.
But he was not yet to the front of the train when bullets first hit the engine and zinged off the steel in all directions. Their original plan of safety failed, the Aztec Royal Guard did the only thing left and had Montezuma move to the far side of the train from the machine gunners and have several of the guard serve as shields. It was only seconds until the bullets would reach the car the emperor was in.
And soon they did. The Greeks did not have sufficient weaponry to shred the cars, but their bullets did tear through the wooden walls and yield considerable damage nonetheless. Windows shattered, holes bored through walls and seats, and one car became flooded when a bullet broke an overhead pipe. Two of Montezuma's personal guard were wounded by bullets, and three other guards on the train were fatally struck. The rest of the Royal Family was fortunate to be in one of the least-bullet-ridden cars of the train, and none suffered more than a graze from a bullet. The total harm to the passengers - thirteen of one hundred and sixty passengers suffering more than trivial wounds - was not especially great, but the attack had been more than enough to shake up the Aztec Royal Contingent, and would be an event that Montezuma and the others on the train were sure to never forget.
Back in Tenochtitlan, the last defenders were slowly but surely yielding guard, unable to hold back the more numerous attackers. The Greeks controlled more and more streets, then the Palace, and before long Tenochtitlan was a city of the Greek Empire.
