Hi Ray I can only tell you what we were told at school. I have been racking my brains to remember the poem we were expected to recite at school It was something about Judge Bradshaw with his decaying body hanging high with Oliver Cromwell and another chap who I have forgotten the name of. I will ask my school friends if they remember and post it for all to read
Judge Bradshaw was indeed exhumed, displayed on the gallows at Tyburn for a day then beheaded in 1661 after the restoration of the monarchy in 1660, although there is some doubt that it really was Bradshaw's body.
"Another chap who I have forgotten the name of" was Henry Ireton, Cromwell's son-in-law.
