In S03E10, we can see a fight outside of the Twins. The men of House Frey are killing Robb Stark’s army.
Did his complete army come to the wedding, which would mean that all of his bannermen are dead now? Or was this only a part of his army out there?
When Roose Bolton and Lord Walder Frey talk about the happenings of the Red Wedding, Bolton mentions that the Blackfish could escape. I guess he refers to Brynden Tully. As Brynden Tully left the room shortly before the massacre ("I need to find a tree to piss on."), he probably only managed to escape alone, not with any men.
Did Roose Bolton had any men with him as part of Robb Stark’s army? If so, were they inducted (and did they help the Frey’s killing outside) or where they killed by the Frey’s, too?
