[4] Many biographical details, such as ranks, degrees, and titles he claimed, are not independently verifiable, deriving from his own writings.
[8] According to his own account, Gayre served as an "officer of the Regular Army Reserve"[9] with the Royal Artillery as part of the British Expeditionary Force in France in 1939, later claiming the rank of Lieutenant-Colonel.
[citation needed] He stated that he entered the Royal Artillery in 1931 as a second lieutenant, was promoted to lieutenant in 1934, and to captain in 1940, later being promoted to major;[7] this progression is corroborated by the London Gazette: George Robert Gair – late an officer cadet of the University of Edinburgh Officer Training Corps – was to be a second lieutenant in the Supplementary Reserve of Officers of the Royal Regiment of Artillery from 5 August 1931;[10] 2nd Lt G. R. Gair, of the Supplementary Reserve of Officers of the Royal Artillery, was to be lieutenant as of 5 August 1934;[11] Lt G. R. Gayre was to be war substantive captain as of 5 August 1941;[12] War Substantive Captain G. R. Gayre, of the Royal Artillery, was transferred to the Army Educational Corps at that same rank as of 27 January 1942;[13] Captain (War Substantive Major) G. R. Gayre, of the Royal Army Educational Corps, was promoted to the rank of Major as of 1 January 1949.
[15] After the war he spent a considerable amount of time in India where he was instrumental in the establishment of the Italo-Indian Institute.
[21] In 1968 he testified on behalf of members of the Racial Preservation Society who were charged under the Race Relations Act for publishing racialist material.
[28] This was not a title that Gayre inherited or was bestowed but rather one that he assumed after he purchased the ruins of the castle[29][30] which constituted the seat of the feudal Barony of Lochore.
[33] In this, he was assisted by his friend, protege, fellow member of the Order of St Lazarus, and vice-president of the ICOC Terence MacCarthy,[34] whose pedigree has been shown to be similarly bogus.
[35] In 1944 Gayre wrote Teuton and Slav on the Polish frontier: a diagnosis of the racial basis of the Germano-Polish borderlands, with suggestions for the settlement of German and Slav claims using photos by the Nazi Hans F. K. Günther and refers several times to "Professor Hans F. K. Günther's authoritative work on German racial science".
Graves and William H. Tucker state that Gayre considered himself a Strasserist, an ideology "which emphasized the 'socialism' in National Socialism, rejecting both communism and capitalism as Jewish-dominated systems that had to be overthrown in favour of an approach based on white racial solidarity."
[39] He suggested that the Shona artefacts which were found at Great Zimbabwe and in numerous other stone ruins nearby, were placed there only after they conquered the country and drove out or absorbed the previous inhabitants; he added that the ones who remained would probably have passed some of their skills and knowledge to the invaders.
[39] Most archaeologists disagree with Gayre's interpretation and conclusions: they maintain that Great Zimbabwe was constructed by ancestors of the Shona,[40][41][42][43][44][45] as were the terraces, furrows and settlements of ancient Nyanga.
