No, I'm confused.
I am reading listening to WoK for the first time and am struggling to imagine the bridges. I'm listening to the audio book so I can't quote passages.
On the first day there is something about not being able to see when carrying the bridge. But then when moved to the front it is easier to run because you can see out.
Then on the day that Khaladin first "wakes" up to being a bridge leader some of the wounded are sheltered behind the bridge. I'm wondering whether it's more of a structure, and thanks for the drawing, but I can't see how that it is dropped in place from one side of a chasm.
