:I think the coverage in British Army during World War I is better, on the whole, and please feel free to edit this article!  I was mainly going from the account of Harry Farr in the paper by Wessely (available online, see the ref). Farr had previously been "sent down the line" to recuperate from shell shock on several occasions, but it didn't do him much good in his trial. I wonder how that account squares with Corrigan?
