Where a=50 archers and m=50 men-at-arms. Note: the men-at-arms are in "thin line", i.e. about 4 ranks deep. The archers are at least 8 ranks deep. Where the forward angled line of archers meets the forward angled archer line of a flanking battle, a "wedge" (as described in the original sources) is formed. The archers have a network of sharpened, six foot-long stakes (x=stakes) driven into the ground in front of themselves, behind which they have withdrawn.
The center battle is commanded by king Henry V; on his right is the vanguard under York; the left battle is the rearguard commanded by Camoys.
The extreme ends of the line (the right wing and left wing of archers, respectively) reach the woods flanking the battlefield.
The french vanguard, and two wings ("horns") of c. 400 cavalry each (an averaging of the different numbers given in the sources), begin at extreme bowshot (250 to 300 yards) in front, filling the space between the woods also. This combined force is under the command of the marshal Boucicault, the Duke of Orleans and constable D'Albret; with the right wing of cavalry led by the count of Vendome, the left wing by the admiral Clignet de Brabant (or switch them, the narratives are most unclear on this point).
There is a second (and most sources say, a third) French battle: the mainguard, a bowshot (or less) behind the French vanguard, which is another 3,000 men-at-arms, commanded by the dukes of Alencon and Bar. The third line would be varlets, all mounted on the horses of their dismounted masters; and some late arriving men-at-arms: the total strength would reasonably be 4,000+, but only c. 10% men-at-arms, all commanded by the counts of Marle, Dammartin and Fauquembourg.
Historically, the French cavalry get shot down and practically make no contact with the English archers of the van and rear (which they charged): and the French dismounted van clustered toward the English men-at-arms and ignored (or avoided) the "wedges" of enstaked archers: but in playing this as a wargame, you can allow a "performance check" on the French men-at-arms; which, if they "pass", they can attack the archers directly in front of themselves: otherwise, they must press into the spaces between the stakes and do their best to break through the English men-at-arms.
The archers may issue out from behind their stakes at any time and attack the French men-at-arms hand-to-hand.
The muddy field restricts cavalry to "trot" speed maximum, and cuts infantry to a walk maximum: a case can be made for further limiting men-at-arms to a half-walk maximum….
Here's a free game sheet, PDF link with the combat values for bases of 15mm to 30mm width. The English archers have "Bow 3" and up to 20% "Bow 4".
Historically, the French crossbowmen (up to 4,000 of them) were pushed back behind the men-at-arms of their vanguard and played virtually no part in the battle. Again, as a wargame, you could dice for this, or just allow the players to try to use them the best they can….
