“Ha! Again: /Said he young Harry Percy’s spur was cold?/ Of Hotspur, Coldspur? that rebellion/Had met ill luck?” (King Henry The Fourth, Part 2)

 “The shadow of Percy Hotspur still hovers over the town – the Politics of the Duke are the Politics of the Town – Transport House is a rash dream, the Daily Herald a red rag! and Communism a nasty nightmare.” (Durham miner, Methodist preacher and writer Sid Chaplin, about Alnwick, the seat of the Dukes of Northumberland, in 1945)

“On Poppy Day/our schools bought red paper flowers. They were for Flanders./I saw Hotspur cursing the smoke through which a popinjay/minced from the battle. Those raging commanders from Thersites to Percy, their rant is our model./I pinned the poppy to my blazer. It bled like a vowel.” (from LII in Midsummer, by Derek Walcott)

COLDSPUR is the personal website of Tony Percy. I was born in the UK, and moved to the USA in 1980. I retired in 2000, and moved from Connecticut to Southport, North Carolina a year later. COLDSPUR is the phlegmatic alter ego of HOTSPUR, my pseudonym as a Listener Crossword Puzzle setter (see www.listenercrossword.com ). (Hotspur.com was already taken, and I was too stingy to buy the owner out.) If you want to learn more about one important aspect of my life, try the following link: An American Odyssey.

This website has been created  to publicize various reports and articles that I have written, as well as alert others to my interests.  To contact me on any matters arising from content on this site, please email me at antonypercy@aol.com.

On October 26, 2017, the University of Buckingham Press published my book ‘Misdefending the Realm’.  For further information, see MisdefendingtheRealm. The book was published in the USA in early May, 2018.

I have decided to list here all the monthly blog entries that I have written since I moved to the new platform, so that readers may have a quick way of finding any piece they are interested in.

March 31, 2020: The Mysterious Affair at Peierls (Part 2)

(I conclude my investigation into Rudolf Peierls by exploring the network of physicists that allowed Fuchs to thrive, and analysing Peierls’s accounts of his dealings with the spy.)

March 19, 2020: Special Bulletin: A Response to Denis Lenihan

(Because of its length, and some new material, I have separated my response from Denis’s second contribution.)

March 7, 2020: Special Bulletin: Denis Lenihan, with More on Sonia

February 29, 2020: War In 1944: Howard’s Folly

(A paragraph in Professor Sir Michael Howard’s autobiography startled me so much that I investigated the facts behind the almost concurrent Warsaw Uprising and the Monte Sole Massacre.)

February 6, 2020: Special Bulletin: Denis Lenihan on Sonia/Quebec

(A coldspur correspondent has submitted a fascinating commentary on my piece Sonia and the Quebec Agreement. Readers are encouraged to contribute to the debate.)

January 31, 2020: The Mystery of the Undetected Radios – Part 7

(I amplify my conclusions about the history of RSS up to the end of 1943 by analysing some fresh research, and attempt to enliven the proceedings by introducing it with an imagined important conversation between Menzies and Gambier-Parry in early 1941.)

December 15, 2019: Border Crossings: Coldspur & Stalin

November 30, 2019: A Thanksgiving Round-Up

(I provide a summary of the status of my research projects, highlighting my frustrations with Christopher Andrew and the BBC.)

October 31, 2019: The Mysterious Affair at Peierls (Part 1)

August 31, 2019: The Mystery of the Undetected Radios – Part 6

June 30, 2019: Dick White’s Devilish Plot

(A new book on Liddell, wartime head of MI5’s B Division, prompts me to examine why two conflicting views of Liddell’s worth as a counter-intelligence officer have never been addressed, let alone resolved.)

(A Special Bulletin to record an email discussion I had with Henry Hardy, after reading his book ‘In Search of Isaiah Berlin’, about his attempts to clarify some aspects of Berlin’s thoughts.)

February 28, 2019: Two Cambridge Spies: Dutch Connections (1) & (2)

(I compare the wireless-related espionage and counter-espionage strategies of the Abwehr, MI5, SOE and the NKVD up to Hitler’s invasion of the Soviet Union in June 1941.)

December 31, 2018: Donald Maclean’s Handiwork

(The surfacing of a newspaper article from 1980 provokes an analysis of whether the British authorities learned more about the spy Donald Maclean than they admitted when Walter Krivitsky came over for interrogations in 1940.)

November 30, 2018: Four More Books on Espionage

(A review of four recent books – two novels, two non-fiction)

November 5, 2018: Special Bulletin: B2B or not B2B?

October 31, 2018: Confessions of a Conspiracy Theorist

(Here I explain why I believe the role of a curious historian is to develop theories that may describe conspiracies, and describe my efforts to gain greater attention to some of the remaining conundrums of twentieth-century intelligence, 26 of which I identify.)

September 2018: The Mystery of the Undetected Radios (Part 3)

(An interruption to the normal schedule to report on the effect of the hurricane on SE North Carolina.)

August 2018: Four Books on Espionage

(Reviews of four books on espionage, three very recent.)

July 2018: The Mystery of the Undetected Radios (Part 2)

April 2018: Double-Crossing the Soviets?

March 2018: Struggles at the Desktop

(Experiences in dealing with various PC support networks lead me to a diatribe against several technology companies, who clearly do not know how to deliver good software.)

February 2018: Sonia and the Quebec Agreement

(My book is launched.)

September 2017: Sonia’s Radio – Envoi

(A summarisation of the SONIA story, with my reflections on its further implications.)

August 2017: Sonia’s Radio -Part IX

(Here I describe the background of MI5’s surveillance of Communist activity, with special attention to its tracking of the movements of SONIA and Len Beurton. The chapter includes a comprehensive analysis of the history of wireless techniques in intelligence. I offer my conclusions about the truth of the SONIA affair.)

July 2017: Web Woes

(Some dire experiences, mainly with my bank, which showed a bureaucratic ineptitude that was beyond belief.)

(A critique of ‘authorised’ histories, and those who agree to write them.)

April 2017: Sonia’s Radio – Part VII

(In this chapter, I analyse the backgrounds and possible motivations of the contributors to the ‘revisionist’ theory of Ultra dissemination, namely that it was fed to Soviet intelligence in Switzerland by SIS – probably via Alexander Foote. All these claims were then magisterially denied by the official historian.)

March 2017: POLARBEAR Has Landed

(An account of my visit to the UK to accept my doctoral degree.)

December 2016: Taking the Cake

November 2016: Sonia’s Radio – Part IV

October 2016: Economists’ Follies

September 2016: Sonia’s Radio – Part III

(This chapter describes how MI5 responded to the threat of illicit radio transmissions to Germany and the Soviet Union, and how the RSS was absorbed into SIS (MI6) in 1941. It also brings readers up-to-date on the movements of Klaus Fuchs, Alexander Foote, and SONIA herself.)

August 2016: Doctor in the House

July 2016: My Experience with Opioids

  1. Hi Tony

    I like your new website. Much, much more user friendly than the old one. Are you doing it yourself or do you have a paid geek?

    As ever

      I worked with a template, and had some training. For a while, I found it all a bit strange (unlearning), but then things suddenly clicked.

  2. Awesome blog, going to bookmark it!

    Dear Coldspur,

    I’ve discovered your piece Two Cambridge Spies in which you refer to my father, Goronwy Rees, as an inveterate liar. Could you please give me any evidence at all for this accusation. Alternatively, print an apology.

    • coldspur

      Dear Thomas,

      Thank you for your post. I think you should read everything I have written about your father, including ‘Donald Maclean’s Handiwork’, and my book, ‘Misdefending the Realm’. I have to add that a few other historians have warned me about your father’s reliability as a witness, Michael Holzman’s public note to me a couple of months ago (see ‘DMH’ above, where he implied I was being too trusting of what your father wrote) being an example.
      Sadly, mendacity was a trait in many prominent figures in this business. Isaiah Berlin regularly lied (as even Henry Hardy agrees). Gladwyn Jebb lied. Dick White convinced Percy Sillitoe to lie to Attlee over the Fuchs business. Etc. etc. Your father happened to go on record more than most.
