Translation
This play comes from ‘exchange of thrusts’ which is before me. Immediately that the scholar who is before me does not put his thrust into the face or chest of the player, because perhaps it was that the player was armoured, the scholar should pass forward with the left foot and in this way he should take the players sword and he can then injure well with his own sword because the players sword is taken and he cannot escape.
Interpretation
The general theme of armizare as a broad rule is to rapidly close the gap from the point of contact to narrow play and finish the fight from there. This should ideally happen in two passes with the feet. The 9th scholar is a great example of the end point of this chain of events.
From wide play, you have first made contact with your opponent as the 2nd master of sword in two hands. At this point, you can still safely back out, but sensing an advantage, you have made the play of the 8th scholar of the 2nd master, stepping through your opponents defensive shell to deliver a thrust at them. The 9th scholar then takes a second step to grappling range so as to finish them off.
The play of the 8th scholar has failed to deliver a finishing blow, due to your opponents armour or clothing either deflecting or absorbing the damage. From the thrust, the point of your sword was high, but your elbows were anchored to your body and your hands held low. Keep your hands in this position as you step through and off to the side with your left foot. With your sword locked to your core like this, use the strength of your step to push the opponents blade, clearing a space for you to step into.
This will lever your opponents blade off to your left. Once the momentum of this move is assured, let go with your left hand and reach over the top. Grab your opponents sword hilt between their hands and twist it outward to emphasis this disruption, as shown in the picture.
If you need to, you can pivot on your left foot, arcing your right foot around behind you to an appropriate angle and distance. The further you pivot, the closer you will end up. As your right foot anchors onto the ground, use it to slide your sword between your left arm and your opponents blade into your opponent. The face, neck, or right armpit should all be appearing as likely targets. From there, you can make a repeat thrust or withdraw the sword completely to posta fenestra and start striking with either the blade or pommel.
Although this is a series of individual steps, it should all be performed as a single flowing movement from the moment of contact as the 2nd master through to the completion of the 9th scholar.
