OK - successfully did this yesterday - thanks for the guide.

First wave - reg hero 229 att (w/armor - level 89) low int - 99.8k warr + rainbow through cata. Losses - 35k warr and rb

Following waves from 2 cities (8 from main city 1.4 mis - 2 from other city 1mi)

20 waves - 20k warr + rainbow 10-20 of each through cata - most losses from second wave - 7k warr - after most losses (twice) was ~2k warr

24 waves - 16.5k war + rainbow 10-20 of each through cata - most losses ~2k warr (twice)

Most heros level 40+ with attack gear

Total troops - 350K warriors

Losses - 60.3 K warriors (much of this I had cooking during the waves) and minimal 170-240 of the rainbows (sword, pike, arch, cav, cata).

Total waves - 45 - time elapsed from first hit through capture - 27min

Longest time between hits - 1m30 (could tighten this up a bit - my first time)

All told - with the number of warriors I had cooking during the half hour or so - net loss 30k warr (5 cities) - and even with no porters sent on any waves - got 1.6MM food, and 161K of other resources - so easily a break even proposition.
