Wow, you did it in the first week? Not bad. I only managed it in the middle of the second week, after buying up all the city upgrades. I need to remember what else I did...
I remembered. So, I killed the militia and hired elven archers, and also took out half of the knights. The rest seem to have survived. I had slightly more archers than you, I don't remember exactly how many, but around a hundred, maybe less.
I see... I didn't hire any elves. I decided to focus on the Castle. Now it's the end of the 3rd week - I took the elven Castle, and in the human city, I built the Capitol, the Castle, and the Knights. All that's left is to build the Angels)))
+ I'm thinking of using elven archers instead of peasants (the peasants are just cannon fodder, they die often) - I want to gather more of them.
Now I'm thinking about where to go next. I'll probably head to the Dwarves - the garrison in the elven Castle (judging by everything, it's the 2nd one) is too strong.

That's a bummer. They took the Castle, those jerks. So, the elves will be used as cannon fodder
