This was a real surprise to me. The first article I found stated Backert was "late" of the Skeleton Army. The second one I found after the first indicates he was actually the founder and General of the Skeleton Army under the alias Alfred Charrington. Check the address out at the bottom of the second article(13, Newnham Street, Whitechapel).
