Yes, because of avalanches. Also, while I'm at it, the LDB isn't caught at the same time Ulfric was. The Imperials just picked up up along the way. Ulfric was captured near Darkwater Crossing and the LDB was captured crossing the border into Skyrim. While some like to assume that these things happened at the same time, people in game don't treat it that way, and considering the LDB doesn't even know how Ulfric was captured, let alone where, I'm inclined to agree with them.
