Sea movement, fires from afar

[jeffr]

A couple of questions:

1. Sea movement - If an amphibeous unit can move 2 provinces, can it move to a land province and then a sea province in 1 turn?

2. Fires from Afar - If I cast this on an enemy force and then engage in battle with that enemy force on the same turn, will the enemy force have units that are wounded and/or have battle afflictions as a result of the Fires from Afar?
(i.e. suppose the flame bolt hit a 30hp unit or for 20 damage, will the unit start the battle with 10hp?).

3. If I'm besieging a castle, will there by an indication of the size of the enemy force inside the castle displayed on the map? (i.e. a typical enemy force "square"). I can't remember, and an enemy force that was once next to me has disappeared (no stealthy units in it) and I was wondering if it went inside the castle I'm besieging.

thanks in advance
