Couldn't tell you exact #s, but it seems to me like 2k Dwarves with an onslaught ritual and ruby dragon could break 1500 TMs with relative ease.
Or, they WD, re-engage, still outhit your attackers, and WD up acres again. Looks like their halflings are pretty much shot as TMs, so presuming they convert to attackers for round 2, you're outnumbered 25v15 in hitters.
Not sure how you'd ever stop them from WDing up acres.
What I'm saying is, I want to see you two war 10 times consecutively until EOA.
