So the Value of Enemy Soldiers is now 25K. This reflects the fact that I successfully defended against two warriors (but died to a third).
The enemy should have 6K Power due to population. I can verify 3 Warriors within Sight so that's 9K. We're missing another 10K. There must be at least one Warrior in his third city so that's 7K Left.
I really screwed up. I moved into a position where all three cities could attack me. I didn't realize they were in Range and I lost "Scout". At least I counterattacked and cost him another warrior and a worker.
I have to group up my centaurs and go all at once. Or at least have them travel in packs. I"ve already lost 2 centaurs and its costing me.
