I've never seen Vignar act that way, i'll look at his dialogue and see what he says.

I don't think the TES universe has battering rams, atleast i have never seen one or heard of one from the NPCs. What i think they could have done is: Ulfric or the DB, or both, could have used Unrelenting force to blow open the gates, seems like the most effective way and with the least colateral damage.
