More research today. There have been many articles in newspapers over the years since the explosion but this section from The Uttoxeter Advertiser and Ashborne Times seems quite underplayed in the circumstances. It was two days after the incident on 1913th day of the war. It reports the events as known at the time but even as this was written they were still recovering bodies. It might seem morbid to go over all the reports in so much detail but I feel I can only do the exhibition justice if I know as much as possible. Going to the crater tomorrow and feeling a little apprehensive already.
