So...
Turn 221: Switch production to Infantry. Move our army by Hamburg into the city.
Turn 222: Cyrus asks for Medicine as a freebie. Not gonna happen. He's got AL now. No one is willing to trade any techs ATM. City keeps building Infantry. Hamburg comes out of revolt (must have bombed the GA), but Caesar lets it starve despite available tiles to work.

Decided not to bother upgrading the 2 Cannon. They'll be upgraded while the army heals after taking Washington. Army starts marching north.
Turn 223: City built another Infantry. Army continues march north.
Turn 224: Built another Infantry, order up an Artillery. As expected, Huayna-Kublai PA comes online. For some reason, I don't get any mouseover text when trying to determine WHEOOHRN status. Very strange. Well, let's get this over with:
Told Caesar to capture Washington.
Turn 225: Infantry kills George's Artillery attacking from Washington. George kills our Scout in Bombay. He also marches three Rifles out of New York. The city promptly revolts & autorazes.

Liz builds Apollo & Broadway. Cyrus also builds Apollo. Cyrus is willing to trade Electricity, but not for cash & not as a freebie. Kill off George's Rifles from New York. We now have a Guerilla II Infantry to support the attack on Bombay. Healed the troops near Washington, since Caesar won't be able to attack next turn anyway. 4 more Artillery will be available next turn to attack the city.
Turn 226: George kills Chinese Cartography Corps in Cuzco! CCC & the Scout made good bait for George. He sent 4 Rifles after the Scout & 1 Rifle & Grens after CCC. Cathy builds another Casing. Lost an Artillery at 89.0% odds. All others win, leaving George with one Rifle at 4.2 strength. BTW, Saladin has researched Industrialism as he's boasting about his Tanks.
Turn 227: Caesar duly captures Washington. Cathy builds another casing. Cyrus is no longer willing to sign a DP. Moved troops into Washington to upgrade & heal. We have more Infantry that I had forgotten were fortified in Antium & Madrid that are on their way to join the stack. Caesar is building a lot of Artillery units. The stack in Washington consists of 10 Infantry, 11 Artillery, 2 MG & will be fully healed in 2 turns, by which time, 2 more Infantry will be in range to join the army from the south. There are 3 Infantry fortified in our Fur forest in case Asoka sends a stack into our territory. If he doesn't, these 3 Infantry are in position to join the invasion.
Our Power is steadily increasing, but we still can't match the behemoths overseas, yet.
Techwise, we don't have any trade options except with Cyrus, who wouldn't trade Electricity for cash. After Electricity, onward to Industrialism. Asoka's Artillery will be problematic. Maybe what we should do is declare war and wait for Asoka to show his hand. He might just be stupid enough to suicide his units onto Washington.
