I finally made contact with Deckhand in 520, when he volunteered to become AlanH's vassal. It seems that kcd_swede and Humbaba had been giving him a hard time. These teams would fight two long wars, which gave me time for my wars in the east.
I conquered neilmeister in 560, then went to war with DynamicSpirit in 740. I took four of his cities, including Delhi, before making peace for some tech in 1170. Before I could rebuild my army for another war, he volunteered to become my vassal in 1230.
The other powers have ended their wars by the time I attack Humbaba in 1290. I capture two border cities, then sign a ceasefire in 1360, when I see a large counterattacking stack approaching.
I attack again in 1500 and capture another city. It looks like it will be a long war of attrition, when AlanH/Deckhand join the war against kcd_swede/Humbaba in 1565. With that, kcd_swede/Humbaba suddenly agree to capitulate to me!
I and my vassals attack AlanH/Deckhand in 1575 and I capture Washington in 1590. kcd_swede had previously been reduced to one city, so I'm not surprised when AlanH captured it to destroy the Viking Empire in 1600. What does surprise me is that this event causes Humbaba to immediately break free from his vassalage!
He's furious at me, but at least he's still at war with the others and he doesn't cancel our open borders.
I capture Deckhand's last two cities by 1630. I lay siege to Warwick (a well-defended hill town), but my first assault with a large cannon barrage is unsuccessful. It's not until I research railroads that I can finally amass a sufficient stack of rifles and cannons to take the city in 1750. I think AlanH had about 25 redcoats in the city, along with a dozen or so cavalry, airships and a cannon or two, when I made the final assault.
I take another city. Humbaba takes one and makes peace in 1785. I finally capture London in 1795 and AlanH capitulates. But I'm still not quite at the Domination threshold.
So...I and my two surviving vassals attack Humbaba again in 1800. I take one city and achieve a Domination victory in 1808, for what I'm sure will be another middle-of-the-pack finish with 121,778 points.
If I had realized that sacrificing kcd_swede would have cost me Humbaba's vassalage, I would have delayed the war against AlanH/Deckhand long enough to reinforce kcd_swede with my own units. I think that delay might have saved me a century, at least. Some more attention to developing my economy/science would have helped, too. AlanH got infantry before I did, and I
really needed railroads sooner to speed my troop movements.
And, incidentally, while I did get the circumnavigation bonus, I only got around to researching astronomy when the game ended. That meant that the Colossus was still working for me
Thanks for the game, and thanks to all of the staff who lent their names to my victory!
