1. Any special rules for supplying this fortress?
2. Any special rules for crushing the event driven revolt there?
(1) In Winter 1920/21, Red GC, suddenly nearly all land based units there died because of lack of supply. Is this a result of winter & White Forces occupying those two regions South of Kronstadt and South of Petrograd? Would building an additional depot level help?
(2) Unloading troops from naval transport in order to crush the revolt there doesn't work (IIRC "invalid region"). Do I have to take any land route to get there?
Regards
Edit: Loosing 5 NM every turn because of those "$§! isn't fun...
