Source-derived summary

Major Henry Hopkinson Augustus Thackthwaite OBE (1 April 1904 – 8 November 1982) was a British soldier and veteran of the Special Operations Executive.

Thackthwaite was born in West London in 1904. His mother and paternal grandmother were French and Thackthwaite was bilingual from an early age. He read physiology at Oxford and worked as a teacher/translator in Beaminster, Dorset before WWII.

Thackthwaite joined the Royal Army Service Corps in March 1940. In 1942, he began working for Special Operations Executive RF section. In January 1944, he parachuted into a drop-zone near the village of Eymeux where he helped organise French Resistance groups, in an operation known as UNION-I. Thackthwaite was exfiltrated in May 1944 to take up an important administrative position of the SOE (RF) section. The General Staff of the French Forces of the Interior (EMFFI) was set up just ahead of the D-day landings in June 1944, and SOE (RF) became the 6th bureau of the EMFFI charged with special missions. In late 1944, EMFFI mounted a dual operation, JUDEX, from an office in the Hotel Cecil in Paris. The two operations were commanded by Col. M. Buckmaster for 3rd bureau and Thackthwaite for 6th bureau.

Editorial reviewA practical starting point whose main value is the path it opens into stronger specialist and primary sources. The current lead gives the account dated anchors—1904, 1982, 1940, 1942—that can be checked directly. The linked authority record independently contributes the date 1904-04-01. The account is most persuasive where Henry, Thackthwaite and British can be independently traced.
Editorial analysis

Why this record matters

The subject matters to the general reference register because the source frames it as british soldier (b. 1904, d. 1982). Its deeper value depends on whether names, dates, institutions and citations support that framing.

Evidence profile

The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated May 1, 2026. The linked authority identifier is Q100274768. 1 of 1 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1904, 1982, 1940 and 1942.

Critical limits

Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.

How to read it

Use the entry as an orientation point, then follow its citations and revision history. Names, dates and institutional relationships should be checked against the original record.
