Von Nachraÿßen (Travelling after)
This is about racing-after
Learn the racing-after,
Doubly or cut into the weapon
Comment: this is so that you shall learn the racings-after quite well, because they are dual, and the first deploy thusly: when he wishes to cleave-in above him, so note while he yanks up the sword to the strike, [and] race-after him with a strike, a hew, or with a thrust, and hit him to the upper opening before the moment he descends with the hew, or fall with the long edge above him onto his arm and with that, press him from you.
Yet another racing-after
Item: When he begins to hew you downward from above, and if he then allows his sword to go down to the earth with the hew: so race-after him with an over-hew to the head before the moment he comes-up with the sword, so is he struck. Or if he will thrust you, note the moment he yanks the sword to him for the thrust, so race-after him and thrust him before he completes his thrust.

The Parter
Is a danger to the face.
Gloss.(Comment): Here note the parter is really dangerous to the face and to the chest; deploy it thusly: When he stands against you in the guard [of] the fool, hew above with the long edge, down from your part to his head, and with the hew remain high with the arms and if he displaces, so hang-in to him with the point, with the long edge above his hilt, and thrust him to the face (as stands pictured hereafter next to this).
