In 1341, John III, the Duke of the sovereign Duchy of Brittany, died, leaving some mixed instructions as to who was supposed to take his place. The war that would come afterward was closely related to the early stages of the Hundred Years War, and would lead to one of the Middle Ages’ best displays of chivalry. The History Guy recalls the “Combat of the Thirty”. It is history that deserves to be remembered.

  • I love History Guy, but take exception to this story as "what can be"; more accurately, "what might have been, if killers really were rule followers (which they ain't)". But, did enjoy every minute, many thanks dude. Someday (as an old white male American from Baltimore) would love to see a black series of the historical civil rights ladies & dudes, from Harriet Tub through Angela Davis and Rosa Parks, or dudes like Nat Turner, through Fred Douglas, and of course the two black Scotus justices, as well as MLK, MX, H. Rap Brown, atheltes and Black Panthers all the way toG Floydd. That's something that "could be..." memorable, and chivalrous of a white dude in engineer's glasses, making a good living on utoob (I hope he is)

  • Warfare of any kind, during any time period is brutal, fighting in the Middle Ages was just on another level, being suited up in full armor trying to hack other men to death with a sword or axe while not trying to be hacked to bits with a sword or axe sounds terrifying. The wounds that these guys suffered during this time are right out of a horror movie.

  • And yes, books were being produced in the pre-Middle Ages and Middle Ages, they were on secular and religious topics and were hand written on vellium and bound in leather or better material. Only nobles and Kings could afford those books and to this day if you tour a palace or a Castle in Europe, make sure that you get to see the private library. Tons of books from the Middle Ages and Renniesance exist in these private libraries. I saw one such private library with my own eyes while touring a palace in Belgium, it utterly blew away several myths about the Middle Ages! And yes, German Castles had real toliets in the Roman style, pre-Renniensance. Again, saw that at Heidelberg Castle. Someone wrote an excellent book that dealt with all of the modern myths of the Middle Ages and imploded them one by one by simply giving actual proofs and naming actual sites. I had that book for awhile.

  • The "code of arms" books from the day (still in private libraries in Europe) do suggest that Knights AFTER the Crusades were supposed to only fight for their liege, not fight nor rob the serfs, honor aristocratic women etc. The idea that there was NO Chivaric code sprang from Karl Marx's writings and he was 100% wrong on everything he wrote about anyways.

  • The modern laws of warfare are an outgrowth of the concept of chivalry. Concepts like treatment of POWs, accepting surrendering enemies, and so on, as well as refraining from using certain weapons deemed to be too uncivilized. There is a practicality to it, in that you don't want your own troops to be abused if they get captured, and maybe more importantly, you don't want to cede the moral high ground representing your own society by stooping to the level of barbarity. As with the old codes of chivalry, modern laws of warfare can be conflicting or irrational, get broken pretty much all the time, and get enforced more often against the losers, but we need them as a ideal to strive for.

It was burned...but only on the outside of the fence. The side facing the church itself was NOT burned. And, if i recall it correctly, the church itself survived, along with the Priest. The church was the only building to survive. Did you run across that information when you did your story? I really enjoy your programs!!!! Bob

  • Chivalry probably owed more to the practice of knights ransoming captive knights since even then money talked! Indeed the reaction to Henry V's decision to execute French prisoners at Agincourt owed less to chivalry than to not executing prisoners worth a valuable ransom. On the battlefield, it probably lasted only so long as a knight was on his horse! Once he was down and encumbered by his heavy armour he would be dispatched in short order by men on foot - as seen at the battles of Crecy and Agincourt amongst others and by what is supposed to have happened to Richard III at Bosworth (A horse! A horse! My Kingdom for a horse!) chivalry didn't enter the minds of Henry Tudor's men who simply butchered the King once he was in their hands.

  • Chivalric rules and behaviour, though influenced by bu the church, had more to do with the nobility looking out for themselves. Most of it pertains to the treatment of a vanquished foe and the fact that you should show mercy and capture him instead of outright murdering him on the battlefield. But, of course, this only applied to noblemen and not at all to common soldiers. This is one of the reason for the outrage at Edward's supposed order to take no prisoners at the battle of Crécy (it was contrary to the chivalric code).

  • Combat, no matter how stylized, is a brutal heartless affair. While it is sometimes necessary we mustn't romanticize the lethal violence people do to each other. Today in the US we have different groups of people who long for open armed conflict to resolve political disputes. Those who have not participated in violent death in combat often hold idealized visions of glory far removed from the smell and screams of people injured and leaking. Call it "fog of war" or simply havoc, most people have no idea, No idea. Once the line has been crossed, once violence begins, the control over one's destiny is lost. From there we are no better than dogs fighting, not rational, only reacting. Stay rational.

  • I live in Josselin near to the Mi-Oak, the site of the battle. There's an obelisk memorial and another to the dead Anglo-Bretons. The current Duke, Josselin de Rohan ( , jokes that his forebears only won that fight by cheating and bringing a horse into a foot battle to break the Anglo-Breton lines 😎. Shortly after that battle was the Battle of Mauron which the Anglo-Bretons won so convincingly that the Franco-Bretons were unable to field an army for 12 years. Its not a battle much mentioned around here although there is a memorial. We have a Fete Medieval that celebrates the towns history. Worth a look.

  • Dear Mr THG, A couple notes on correct pronunciation of a couple of words-- First, is the word 'chivalry', and all of its derivative words. Two areas of focus on this word-- You often, in this piece, put emphasis on the 2nd syllable, 'val'. The only emphasis for the word, 'chivalry', and any of it's derivative words, should always be put only on the 1st syllable, 'chiv'. When doing otherwise, you sound like you are unfamiliar with the word. 2nd point is that the 2nd syllable should always be pronounced using the 'uh' sound for the 'a' in 'val', as you would pronounce the 'e' in the word 'the'. This is the correct manner to pronounce this word when speaking the English language. Otherwise, you come across as sounding unacquainted with word 'chivalry', and it's derivatives. A second word you mispronounced is the name of the French city of Nantes. Both in French and in English, the correct pronunciation of this city of Brittany, (in French, la Bretagne, or Breton), is 'Naunt'. In neither language are the letters 'es' at the back end of the word pronounced. You assumed they should be pronounced like the word 'ace'. Those two last letters in 'Nantes' are silent. They are used because Nantes, itself, is a feminine word. Unless a word in French has either an 'accent aigu' (which is above a letter 'e', and stants upwared from left to right), or an 'accent grave' (where there is also an 'e', and an accent mark above it that slopes downward from left to right, making the same sound as the first 'e' in the word 'ever'), should an 'e', in the French language, be pronounced that way). Most 'e' letters in French are typically pronounced like the 'au' is pronounced in the word 'haunt'. I appreciate your shows. You don't mispronounce words very often. But these 'faux pas' ('false' or missteps) jumped out at me. Hope you don't mind getting educated a little, as you educate me and many others. Keep up the great work!

  • Nice to hear you treat this topic! For some reason I thought you focused mainly(if not exclusively) on American history. However, I think I might hear a little bit of the Howard Zinn take on things creeping in here and there. Yes, chivalry could often cause its very practitioners to snatch defeat from the jaws of victory. One of the worst examples of chivalric aspirations impeding success was some 45 years after this at the Battle of Nicopolis, where Christian knights could not reign-in their competing notions of unadulterated glory, and the Muslims showed them what it looks like when your side is able to cooperate with itself, shrinking Christendom as a result! Probably one of the finest examples of truly chivalrous behavior would be the Knights Hospitaller at the Great Siege of Malta in 1565. Although it was a bit after what is classically accepted as the "Age of Chivalry", I'm confident that the Knights of Malta's actions would've been revered by any 11th, 13th or 14th century epic poet! Btw, will you PLEASE sing a rendition of "It's Not Easy Being Green" at some point?!😀😂

  • Hello THG, can you please do a couple episodes about the USS Thresher and USS Scorpion? These two terrible maritime disasters are very significant in US Naval history, and are also poorly understood today. Not only are the actual causes of the disasters barely known by the public, the time period itself is generally poorly understood and the results of the disasters barely receive mention. USS Thresher and USS Scorpion were built at the height of the cold war utilizing the most modern technologies available at the time, under the direction of the father of the Nuclear Navy, Admiral Rickover. The two subs were very different, with the Scorpion built to exemplify underwater speed, while the Thresher was built for deep submergence depths and sound silencing. This was also at the beginning of the nuclear navy, when the traditions and expectations we nuclear sailors hold as ironclad today were just being established, and were frequently challenged by non-nuclear entities like admirals and congressmen. The actual disaster that befell USS Thresher is well-documented, just poorly presented in modern visual media. Most documentaries blame the disaster on "flooding", clearly unaware of the implications that word means to any qualified submariner. The nuclear side of the disaster is also rarely discussed, but had every bit as much of an impact on the outcome as the failure of the EMBT blow system. Reactor operating procedures at the time valued safety of the reactor above everything else, so when a scram occurred, the operators shut the main steam isolation valves to limit thermal stresses on the reactor due to plant cooldown while restarting the reactor. Without steam for the main engines or turbine generators, the ship (which normally drives itself to the surface with its main engines) was dependent on its EMBT blow system to return to the surface, and this failed when needed. I have seen various transcripts of the communications between USS Thresher and USS Skylark that day, but what stands out to me most is the final message. Official transcripts say "exceeding test depth", but one of my shipmates who met the underwater phone operator from the Skylark says the full message was "make peace with your maker, exceeding test depth". The actual collapse of the pressure hull occurred so quickly that the crewmen and shipyard workers onboard were dead before they knew it. The search for the wreckage is quite a story as well. Because Thresher sank in deep water, they could not initially visit the wreck to see what happened, so initial investigations had little information to go on. The location of the Skylark was well-known, but a submarine can travel an awfully long distance as it sinks to the sea floor. Ocean currents, thermoclines, and other effects can throw off the search. They searched with the bathysaphe Trieste and deepwater towed cameras, and ultimately found the wreckage in over 8,000 feet of water. Changes from this disaster were extensive and long-lasting. The SubSafe program was a huge step up in manufacturing and maintenance standards for vital systems aboard submarines, and the nuclear community significantly revised their operating procedures after Admiral Rickover realized that a safe reactor on the bottom of the ocean wasn't that safe after all, resulting in the fast recovery startup and tactical situation clauses in most procedures. To this day, the USN still visits the wreckage of the Thresher and Scorpion every few years to ensure that the nuclear reactors onboard are not a threat to the environment. As a submariner, I would very much appreciate a video covering the full, detailed story of the USS Thresher.
