The whole business regarding sieges is starting to baffle me.
CASE 1
In my current PBEM game, I had Hooker (active leader) and 2 divisions besieged in N.O. A relief force was attacking Ft. Pike. I had Hooker and the boys use riverine movement to leave N.O., go out to Lake Ponchatrain, and then to Ft. Pike. The game showed these moves on the map to my satisfaction. I was to arrive on Day 12. There was plenty of riverine capacity available. Everyone was in supply. Hooker was active. There were no enemy units in Lake Ponchatrain.
After the turn resolved, Hooker and the boys were still in N.O. The replay showed that they never left.
My guess was that Hooker deactivated. My opponent (OneArmedMexican, whom I recommend you play sometime!) thought the game required me to move into Iberville first in order to use riverine. If so, it's not normally required.
Any suggestions why?
CASE 2.
As the union player I was also besieged in Bowling Green, which was a depot. I owned the river, having a significant presence of gunboats and transports. There were no other enemy units around, other than the besiegers. The nearest supply depots were Louisville and Cairo. Both are more than 5 zones away, IIRC, by river. I also had the railroad to Louisville cleared, operational, and controlled. It's four zones away. I was unable to receive supply for my units or for the depot from any source, including the transports.
My assumption was that the access to the river did me no good becuase of the distance. I thought the transport might assist, but apparently it does nothing for land units. The overland route was no good, even though it ended at a river I controlled. I suppose this means you can't combine supply by both river and rail.
Any other way to read this?
CASE 3.
In yet another battle, this one at Alexandria, my army retreated into Alexandria, allowing my enemy to besiege me. I came out of the town, in defensive mode. Reinforcements were sent via movement and via rail to Alexandria. The next turn we fought and I was retreated into Alexandria, where I was again besieged. Both my opponent and I were puzzled about why my units retreated into a besieged condition after a battle.
Any thoughts?
