Hi LestaT

My brief input:

1) You can only control 20 units at 1 time and only if re-inforcements are led by a captain. Therefore if your general has 10 units and the re-inforcements led by the captain has 10 you will control both armies. If both armies have 15 units you will only control 5 of the re-inforcements but as your units leave the field or are destroyed you will be able to take on other units up to the limit of 20.

5) The garrison required for a city is dependant on so many factors other than city size such as distance to capital, governor's managment/influence etc. An important point is that a garrison can only give you a maximum of 80% public order so having 20 units of town watch in a town with 500 inhabitants is wasteful.

You really must check out the guides in the Guide section. Our resident writer FrogBeastEgg has as usual produced another noteworthy effort!!
