Siege
The besiege option assumes you have an army and have already traveled to the Fief of your chosen enemy. Each attempt at Siege will cost 10 of your 90 game days per turn. When you choose this option the Game will display the ID of the Fief you are in and ask you if you really want to Besiege that Fief. If you answer yes the game will calculate the value of the sieging and defending forces . The computer then determine the winner for that ten day period of siege. There is always the risk that the garrison of the fief will defeat you so strongly that your Army will retreat to another Fief. Watch for this and be careful where you're Sieging. If you want to go back to the travel menu you just press return. If you want to siege again you respond with a 'y'.
If an enemy army comes and attacks you while you are besieging a fief, the siege is broken only if you are defeated.
