Hi Canopus and Welcome aboard !

Yes I do, Sir.

As HRE sitting on the bridges bordering France, with 6 EXP >5 Serpentines. That is a different case altogether. You pound as the enemy approaches and then let them over the bridge. In that case actually I've had a lot of success.

Note however, if I'm not mistaken, OP's case in point is vs Mongols.
