Germany has a navy with transports and land units on them in sea zone ‘A’ and England has a navy in that same sea zone, they are at peace at the moment. The second the Germans declare war on England/France, do they have the ability to leave that sea zone without any combat occurring or does England stop them in combat?
Or is there a way that Germany with the intention of war, can avoid that navy yet strike with that same force on the same turn?
