(p.57/#1) (Patiente: Porta di Ferro Stretta vs Porta di Ferro Stretta; beginning with engagement) If you are set in porta di ferro stretta with the right foot forward against your enemy, and he is set in the same but in such way that the true edges of your sword touch against each other; you will stay alert that if he should make a sfalsata of his sword under yours, to then come at you with a thrust to the chest; in that moment that he wants to disengage the sword, you will pass the left foot forward making a half turn of the hand and with the true edge of your sword you will come to press his sword towards the ground and so with admirable quickness behind his sword you will drive a thrust into his chest, and your right leg needs to follow somewhat behind the left and the sword needs to find itself in the fashion of coda lunga alta, pushed as far forward as you are able.
