Bernard! Regarding your latest Uhtred book, the Death of Kings as you have stated the location of the Battle of the Holme is unknown other than that it took place somewhere in East Anglia. You located it in your novel along the valley of the Ouse between Bedford and Huntington. A very logical choice! What caught my eye was that there is a place between Huntington and Peterborough (both Roman and Saxon-Danish settlements) called Holme, in the valley of the Nene as it becomes tidal and along Ermine Street (which skirted the Fens). We know that the Saxon and Danish armies of the time used the old Roman road network for their lines of advance and retreat. Any army consisting of Danes from the 5 Boroughs and Northumbria together with those of East Anglia would use Ermine Street (London-York)for their line of communication as indeed would a Saxon army from London ravaging East Anglian/ eastern Mercian territory west and south of the Fens and around Cambridge and Huntington. Just a coincidence? It does make for a good fit. I wonder whether any archaeological digs in the area have shown any relevant results! Mike
