The first appearance of the term DEFENDU was as the title of W.E. Fairbairn’s 1926 publication on his method of “scientific self-defence”. We are further informed that this treatise is the “official text book for the Shanghai Municipal Police, Hong Kong (sic) Police and Singapore Police”.
The usage of DEFENDU is found twice in the forward of the 1926 edition. However, in this context it would be important to remember that Fairbairn claims almost complete originality in the methods presented, stating however that they are drawn from several different sources. In this regard it would not be applicable to use Asian terms or nomenclature, i.e. “Jiu jitsu” or Western descriptive phrases such as “Chinese Boxing”. Fairbairn claims originality in the methods presented, hence an “original” descriptive term would be apropos.
This situation however caused confusion among readers of this edition and hence in the 1931 edition of Fairbairn’s work the title was changed to “Scientific Self-Defence”. This was done to make the content of this edition more clear to the average individual.
The term DEFENDU is found again in Biddle’s work “DO OR DIE”(1937). Fairbairn is credited with developing this method. It is interesting to note that Biddle makes a clear distinction between “Jiu-Jitsu” and “Defendu”. The 1944 edition of Colonel Biddle’s book also uses the term DEFENDU and the text is virtually the same as in the earlier edition. Excepting one important point: In the later edition Biddle refers to Fairbairn’s book “GET TOUGH”. However, he does not correct the fact that Fairbairn by this time was a Major serving with US Forces(not Assistant Commissioner of the SMP). There are of course obvious reasons for this lapse.
The point however is that the term DEFENDU relates too much earlier methods espoused by Fairbairn and did not reflect his thinking at this time (1944). The British edition of “ALL IN FIGHTING” also mentions DEFENDU, but just as a passing comment in reference to Fairbairn’s earlier works. “GET TOUGH” the US reprint of “ALL IN FIGHTING” refers to the close combat fighting method present as the “Fairbairn System”.
So what is the point? Well here it is……… I believe that the changes in terminology referring to LT. COLONEL (NOT CAPTAIN, NOT MAJOR, as so MANY ill informed individuals refer-DO YOUR DAMN RESEARCH!) Fairbairn’s methods reflect a CHANGE (growth if you will) in his COMPLETE ATTITUDE regarding close combat.
In describing his MOS for paperwork detailing his duties and responsibilities in connection with being awarded the “Legion of Merit”, Fairbairn refers to his methods of close combat as “Gutter-fighting”. Consider if you will the change in attitude from “Scientific Self-Defence” to “GUTTER FIGHTING”. Fairbairn further elucidates his feelings by describing two key elements: VEHEMENCE and ARTIFICE! “SCIENTIFIC” self defense this is NOT!
Now for those who have proposed that DEFENDU remains the POLICE “version” of the Fairbairn method and make a distinction as to the military method, well consider that after WWII the manual of choice used by POLICE agencies under Fairbairn’s consult was “GET TOUGH”, reprinted in the language of that particular agency.
Now as to the possible origins of the original term DEFENDU. I have over the years heard several stories. Some were simply ridiculous in light of the facts we KNOW! Two however stand out as possible(and very plausible) candidates. First, is the simple use of DEFEND combined with the well known term jiu-jits”U”. Hence, DEFENDU. Aside from what others may claim, Jiu Jitsu(of this period) influenced Fairbairn far more than even he was willing to admit. And that goes for the staple methods of the edge hand, chin-jab, and even the “tiger” claw. Jiu jitsu had these very blows and gave great credence to their effectiveness in “real” combat (YES! this can be verified by books, manuals, etc. in the writer’s possession) these “rock crushing” blows HANDS OFF, however predated by usage in turn of the century Jiu jitsu manuals describing these Atemi) were extant in “real” Jiu jitsu for centuries. As far as the claims of GREAT influence by “Chinese” boxing methods, such as Chin-Na, Ba Gua, Hsing-I, etc., I feel that the evidence denies this (Yeaton’s letter concerning Fairbairn’s thoughts on the matter).
Hence, the use of DEFENDU pays some homage to Jiu jitsu, as well as giving the Western flavor to Fairbairn’s methods.
