The second attack was very close to crossing the 1.5 odds ratio which is needed to drop fort levels by 1 full level.
That I didn't know, thanks for the info. I am currently fighting for Sevastopol in my PBEM game in turn 16. After the turn action, the city is completely isolated, but I didn't attack it yet, as I am still in the process of clearing the mountains to the east. So forts level in city still at 5. I hope to finish it before the end of the year, but mud is coming and the railhead is at Nikolaev. So it might be hard to maintain myself there for 3 mud weeks and I might need to pull back a bit, giving the Soviets time and space to reinforce.
