Read it through once

I was not of a rank to make suggestions, or I would have suggested that if we went faster we should get by sooner. It seemed to me that it was an ill-judged time to be taking a walk. Just as we were drifting in that suffocating stillness past a great cannon that stood just within a raised portcullis, with nothing between me and it but the moat, a most uncommon jackass in there split the world with his bray, and I fell out of the saddle. Sir Bertrand grabbed me as I went, which was well, for if I had gone to the ground in my armor I could not have gotten up again by myself. The English warders on the battlements laughed a coarse laugh, forgetting that every one must begin, and that there had been a time when they themselves would have fared no better when shot by a jackass.
