How do you conquer a city in evony?

If you are a new player I recommend conquering a lvl 1 or 2 flat. For that you get about 1000 warriors 1 hero and 200 sWordsmen to guarennte victory. ( Remember to scout the flat first ). Then you go to Map on the top right of the screen and click on a lvl 1 or 2 flat. then you click attack and enter what amount of troops you want to send then click attack again. Then wait for the reports saying if you conquered the flat or not. For scouting get 50 scouts and click scout instead of attack.
