Taking on account some of his previous deeds I strongly doubt it was a mistake. I gave a precondition (ultimatum) under which I would break the NAP, Zhao ignored and a turn after it I said our NAP is broken. It was turn 15. Zhao attacked on turn 17 and he may say, of course, that he thought something or anything else - I don't care. This turn I had 3 my provinces including capital overwhelmed by caelian forces, my ally Ulm was also attacked. But I may tell you for sure that I would easily beat the force he sent to my capital if it was next turn when I planned to set my chariots and mages to patrol. I expected air attack it but not this early.
Also, I understand that it is too late but I am almost sure that if it was not this way, I could beat all his huge mammoth army because I would have 12 mages able to skellspam, rage and terror, about 100 chariots, horde of archers and poison slingers and 3 smiters. Most probably, even now I am able to beat him but I don't want to check.
Enough said. Our decision is final because this game is no more a pleasure for us. I don't want to publicly blame Zhao - it was his choice. I just made my conclusions and you may or may not make yours.
