My point is that Agincourt wasn't just remembered as a great victory, it was remembered as a great and surprising victory. I don't think you can just handwave this away by saying "Oh, of course people would say that, they had to please their anti-Armagnac lords", because propaganda considerations would apply to the recording of virtually every battle of the time period, but most battles weren't portrayed as having a surprising outcome.
Or else they just weren't expecting the English to advance in the face of such superior numbers, and consequently weren't ready to launch an immediate attack. According to the French chroniclers, the French charge, when it did come, was disorganised and not at full strength, which would suggest that they hadn't been formed up and ready for immediate action at the start of the battle.
This would also explain why the crossbows and other infantrymen didn't take much part in the battle: the French army was taken by surprise, and didn't have an opportunity to form up properly before going into action.
Even if all the English archers were travelling on horseback, which can't actually be presumed, they'd still have had supply waggons, camp followers, and the like, who'd have slowed them down. Plus a lot of the English had picked up diseases at the siege of Harfleur, which would have further slowed them down.
To sum up, you are repeating the traditional English scenario of the stupid and inept French without even trying to look at the other possibilities, which do not involve fundamental stupidity, inexperience and other similar factors. The argument that the French were vastly superior in the numbers because otherwise Agincourt would not be remembered as a
surprising victory is not very convincing because this status exists (AFAIK) mostly on the interested side and to a great degree is a byproduct of a propaganda. How about Trafalgar saving Britain from the French invasion? Or how about Poltava getting practically the same status in the Russian propaganda? This does not mean that Agincourt was not
important victory, it most definitely was because, while (according to Jean Favier) it did not immediately change much in the Franco-English situation, it resulted in a fundamental political change within France leaving John Fearless as the most politically experienced and military powerful figure with a resulting English-Burgundian alliance.
If anything, as I already mentioned, Montgomery (there is no reason to doubt either his military competence or patriotism) spent a single word on it vs. 6 pages on Crecy. Why? Because Crecy
was a surprise, the 1st major battle which demonstrated advantage of the English tactical system. By the time of Agincourt it was the old news so for the French it was more along the lines “oops, we had been beaten again”. When the tables are reversed, I don’t recall the English sources considering any of the French victories as “great” or “unexpected”. Did the English
expect to lose at Patay, Fromigny or Castillon?
To start with, if the French had “such a superior numbers”, why would they chose a narrow position which did not allow them to use these numbers in any meaningful way? Just few hundred meters back or forward they’d have a wide opening allowing a wider front. Why were they waiting for the reinforcements (including Brabant troops) if they already had vastly superior numbers? Why didn’t they engage in a battle few days earlier when the armies were facing each other? (Delbruck considered this an indication of their numeric weakness). Then, by that time, with the English system being well-known and feared, it became reasonably obvious that the best way to deal with it is to attack the English before they take a good defensive position (it does not look like the French had any field artillery so the “ultimate solution” was not yet available) so just waiting (for what?) did not make a slightest tactical sense.
Why, if they were so superior in numbers, didn’t they attack until forced to do by the English fire?
Why, if d’Albert did not have any influence, was the bulk of the French knights dismounted? If the story based upon their chivalric arrogance and an absence of subordination is true, then we probably should expect rather Monthlery schema where in absence if the strong leadership most of the knights chose to fight on a horseback than one of Poitiers where most of them had been dismounted on a royal order. Shouldn’t there be protests (from the Duke of Orleans and down the social ladder) that d’Albert (and Bussicout?) chose a position which prevents an effective deployment of the superior numbers of the French knights?
They did not expect the English attack? Fine, but if they had (as the Burgundian sources imply) many thousands archers and crossbowmen, why wouldn’t they use them to guard the front? After all, the French were not completely inexperienced nincompoops. BTW, the Burgundian sources give reasonably sane numbers of the men at arms (which fit Delbruck’s numbers) leaving the “huge part” to the unrealistic numbers of the archers (not available at that time) and the foot soldiers which did not manifest themselves in any way before, during or after the battle or even campaign in general. Are there any documents explaining how they had been raised, paid, etc.? BTW, how would they be raised in a rather dynamic campaign to start with? France of that time was quite short of the foot soldiers so this could not be done by a click of the fingers, especially in the area where the Armagnac faction was not too popular.
Even with the dysenteria (getting which was not exclusively English privilege), the English army consisted of the professionals (biography of St. Louis can give you an idea how the medievals we’re dealing with dysenteria without slowing down
) used to the long marches. The peasant levy (why would anybody decide to call it on that stage of the 100YW when uselessness of the idea was obvious) would move in a much lower tempo slowing down the rest of the army even if just because it would involve a much greater train slugging along a single road. OTOH, a reasonably small (see the Burgundian numbers) force of the predominantly man at arms with some crossbowmen would move at approximately the same or even higher tempo (because they would not waste time on looting and burning each and every village on their way).
Then, while trying to explain how these thousands of the archers and crossbowmen were deprived of fighting, you are avoiding an explanation of how they were raised in the first place. If we stick to the Burgundian numbers, there would be approximately 3,000 crossbowmen (comparable to the number of the Italian mercenaries at Crecy) and 8,000 archers split between the advance detachment (which means that half of these numbers should be easily available to react to the English advance and fortification of the position) and the main body. Where and how had they been raised? The crossbowmen were professionals so there should be some indication of their existence: people of that period had been bureaucratic enough and, they would have to be raised (and paid) over a big part of France and marched to the region of fighting but somehow they were not present in the numbers adequate for preventing the English crossing of the Somme. 8,000 French archers is even more intriguing taking into an account that the edicts ordering archer practices and organization of the free archers were a matter of future and that the French archers did not manifest themselves in any serious way during the 100YW. There were
some but, as de Comnin stated, they were useless unless available in the big numbers.
Anyway, this subject was discussed ad nuaseum many years ago on then functioning SHM to a complete stalemate and I do not think that we are going to end up with some fundamental discovery or with convincing each other so I’d rather stop then continue at a risk of ending up with too heated discussion.
