Rod Collins, a Lincolnshire local historian has stolen some of my thunder! He came across another (quite gorgeous) broadsheet describing the showdown and capture of the Rebels from another angle and was similarly intrigued. His impressive panel of commentors has concluded the location of events very precisely and provided some excellent background information. Have a look at Rod’s excellent site and I’ll include some of what I have learned in my posts later this week.
Thanks again to Uncle Bill (clearly a far better Googler than me) for the lead.
