The largest siege I ever saw in BM was on the FEI - to take Anacan from Antoza.
I know it's not the largest one in the game, but it was something like 50k CS versus 24k.
Four times they came, and four times they broke. But not the fifth.

I've been on FEI a long time, and I can't think of too many successful sieges. Kindara is an outlier because if I remember correctly, we successfully sieged and took Masahakon, Hatdhes, and Azros in a relatively short time.
When we fought Cathay, we only had two real opportunities to assault a city. One was at the very beginning before we'd had time to gear up and buy SEs. Second was when the whole realm got banned, and I didn't really want to take advantage of that. Pretty much all the time in between, the militia garrison was so large in Taop that we wouldn't have had much hope to win, even with all the mobile CS Kindara and Zonasa, if Cathay, or allies, managed to get even a small number of reinforcements to Taop.
