I got a DoW from Izzy, who happened to be pleased and the same religion as me, and roughly the same power as me (she was just slightly less.) She caught me unprepared, though, and the city she moved to attack had only an Archer and Ax in it. She moved her stack, consisting of 2 Axmen, 2 Spears, and 2 Chariots onto a nearby hill. She then proceeded to... sit there. So I built a spear, and she continued to sit there. A city wall? Nada. Another ax and spear? Well, she doubled her pile, but still did nothing.
Meanwhile, I'm building a stack of Swordsmen, with a few other units thrown in, at another nearby city. When I start moving that stack towards the original city, her units start spazzing out, moving half the stack onto the road between the two cities (a 1 tile lane between the coast and some mountains) and the stacks move back and forth between the road and the hill each turn. Mind you, the road tile is right next to the city, but she's content to wander back and forth, not even pillaging the roads or the mines. After a few turns of waiting to see if she actually does anything, I finally move my stack around the mountains, and through her territory and end up on a forested hill next to her troops. Now she finally decides to suicide against my stack.

Later in the same game everyone is at war with Hannibal, the lone Hindu in a Jewish world. I join the dogpile and prepare to invade by sea, as there was a narrow, but wide sea between our territories. I controlled some clams right on the cultural border with Carthage, so I parked a few Triremes on top to defend. Hannibal seems to be cranking out a Trireme at his capitol every turn or two (this is a Marathon game on a huge map) and suiciding them against my stack, which works for me as I'm playing Vicky (Imp) and had the GW. Easy GG points. I finally get my cats and macemen loaded up and shipped over the sea, only to find Carthage defended by 1 Maceman. Easy pickings at the price of a catapult, and Hannibal is already eager to capitulate.
