1550 (0): I put almost every city which will benefit from a factory onto a pre-build. Since our offensive is stalled, this seems like the right time to suffer through the process of getting factories built.
Our vulnerable army stack isn't bombed in Mongol territory. We lose the isolated cav army, of course (0-1).
The Celts found a new city next to the rubber. We should be able to keep them from hooking it up, though.
Our modest hoard of 732 gold makes us the richest nation on Earth, Pliny reports.
1555 (1): We defeat a Celtic stack of six (three guerrillas, three cav) landed next to New Ghulaman in Arabia (6-1). But we're weak in Arabia, so I send over some reinforcements.
We lose a frigate to the attack of a Man-o'-War (6-2).
1560 (2): We wipe out a Celtic stack of thirteen landed next to Behistun (19-2).
We overrun a single English cav landed next to New Bampur in Egypt (20-2).
The approach of our armies scares two Celtic workers off the rubber tile--though we lose a turn of healing, of course.
1565 (3): We defeat a Mongol rifle/MDI team landed on the desert island (22-2).
1570 (4): Our armies heal.
The Celts are bombing Antioch, presumably from an aircraft carrier.
1575 (5): We eliminate a Celtic stack of four landed between Birka and Behistun (26-2).
We destroy four units from a Celtic stack of six landed near Fustat in Arabia (30-2).
1580 (6): Research down to 0%, Industrialization still due this IT.
We finish off the last two Celtic units in Arabia (32-2).
We get some reinforcements, including the second infantry army and twelve artillery, sailing towards the Celtic continent, in five galleons escorted by ten frigates.
Antioch loses its temple to Celtic bombing.
New Zohak in Arabia becomes a new Celtic bombing target.
Our reinforcement fleet isn't attacked.
Industrialization --> Corporation, due in six turns at 40% research. Espionage comes into consideration too, but it looks as though we can reach Refining (to see where the oil is) under our own power fairly quickly, so I'd rather do that.
1585 (7): I switch eighteen towns over to factory builds. Gordium's completes immediately, as we dump 478 shields from the pre-build.
We wipe out an Ottoman stack of three landed next to New Bampur in Egypt (35-2).
We crush a Celtic stack of twelve landed between Birka and Behistun (47-2).
The usual Celtic bombing runs against Antioch and New Zohak.
1590 (8): We crush four Mongol and two Celtic units landed between Birka and Behistun (53-2).
Our armies on the main continent (except for one watching the rubber) and the reinforcements sent by sea unite next to Hovd.
I put together a complete coastal screen (military units only

) on the small desert island, freeing the army there for other employment.
Antioch has lost so many citizens to Celtic bombing it's now in Love status.
1595 (9): We take and raze Hovd, held by four rifleman and three cav, gaining four workers (60-2).
In Egypt we kill two English cav landed next to New Bampur (62-2).
This turn's Celtic landing by Behistun is just one guerrilla (63-2).
We squash a Celtic stack of six near Fustat in Arabia (69-2).
Pardon me for only playing nine, but we're at a decision point so this seems like a good place to stop.
Six elite victories this round didn't produce a Great Leader.
Edit: Some confusion between Antioch and Arbela corrected. It's Antioch the Celts have been bombing.
