A little about my background
Although I worked for nearly thirty years in the law and related fields my main passion has always been for military history
, with a bias toward the high Middle Ages
and Tudors. Living in the heart of the historic Anglo Scottish Borderland stimulated my interest in 'The Steel Bonnets'
- the sixteenth century border reivers. As a boy I read Scott and classic accounts such as 'Border Raids and Reivers'
by Borland and latterly George MacDonald Fraser's 'The Steel Bonnets'
I left legal practice in 2004 to concentrate primarily upon authorship.

Silvie and I have had our 'Spy of the Century' published by Pen & Sword, whilst the current joint offering from Rosie and I on the Siege of Alesia 'Caesar's Greatest Victory' has been published by Casemate. For them also we've embarked on a series of 'Little Books' - loads of fun to be had!
I have done, and continue to do a great deal of historical re-enactment and interpretation for schools, community and local history groups, covering a range of period interpretations from Late Roman to WWII Home Guard. Rates are around £150.00 - £200.00 for whole or half day.
This interpretation role has involved working with a number of challenging and challenged groups, special needs education, recovering addicts, asylum seekers and the work has introduced and stimulated debate on citizenship, individual aspirations, cultural and social influences, diversity issues and religion.
Tony Foxton has been kind enough to comment on his blog:
My personal dealings with academics has had a number of rewarding outcomes, outcomes that have developed me as an Historian and as a teacher . I think I am able to call John Sadler a friend, he is a Fellow of the Royal Historical Society and has been a lecturer at Durham, Newcastle and Sunderland Universities. He has over forty publications to his name - an impressive academic pedigree I think you will agree. He is always willing to collaborate and share his work, which has enabled me to enrich my teaching. Two examples stand out. Firstly, his enthusiasm for the Border Reivers has encouraged me to squeeze this topic into my Year 8 scheme of work, despite the very limited time allowance. His prose and anecdotes add life to this interesting aspect of Northern Heritage. I was also lucky in that John spoke to me, and gave me sections from his book ‘The Great Siege of Newcastle’, which has allowed me to build my teaching of the Civil Wars around a local aspect, focusing on the events and consequences in our region, which has enabled students to relate more closely with the era, and as a result have, I feel, more enthusiasm for the topic.
Married, with two adult daughters my interests, besides an obsession with military history, include fellwalking, reading, cinema and theatre. I do also have an interest in historic swordplay, particularly rapier and dagger.
My approach to history is to make the experience of telling or teaching as meaningful and intereactive for the audience as possible, with displays of clothing, arms, armour and firearms, demonstrations of swordplay, musket drill and the odd dash of drama! I see delivery as much a performance as a lecture!
Listed below are examples of the various interpretations on offer:
- A Roman auxliary soldier stationed ar Borcovicium (Housesteads) describes life as part of the Wall garrison, a celtic woman living in the vicus, provides the civilian view.
- One of King Harald's Housecarls recalls the bitter fighting, firstly against the Norse at Stamford Bridge and also against the Normans at Hastings.
- Bannockburn - an English Knight returning from the battle seeks to explain the reasons for the defeat.
- Crispin's Day - one of Henry V archers describes the campaign and battle of Agincourt.
- Flodden! John Heron the 'Bastard' of Ford recalls his part in the destruction of the Scots army.
- The Steel Bonnets: Sir Robert Carey tells of his 'stirring' days on the frontier and the capture of the notorious reiver Geordie Bourne.
- Marston Moor - one of the few survivors of Newcastle's Whitecoats describes the fight.
- Culloden - Drummossie Moor; a member of Clan Cameron, fleeing the field, pauses to tell how the Jacobites were defeated.
- Riot; a miner from Bywell describes how he and his wife became victims of the bloodshed in Hexham Market Place in 1761.
- An affair of honour - a gentleman, about to meet an opponent explains the importance of the 'Code Duello'; a duel is then fought!
- A Close Run Thing - Waterloo; Captain Cavalie Mercer of the Royal Horse Artillery gives an account of his role in the defeat of Napoleon.
- The Valley of Death, a survivor of the 17th Lancers tells how the Charge of the Light Brigade came to occur.
- Tommy Atkins - 1st July 1916; A private of the Tyneside Scottish describes the events of the first day of the Battle of the Somme.
- The Longest Day - D _Day June 1944; a corporal of the Green Howards relates his experiences during the assault on Hitler's 'Fortress Europe'.
