This is about the Zornhau (wrath strike)
Whoever strikes at you from above,
the point of the Zornhau endangers him.
If he sees it,
take it up and off without danger
hold against him,
wind, and thrust again. If he sees it, strike him low.
Remember this,
Strikes, thrusts and guards, be weak or be strong.
Indes, Vor und Nach,
take your time and analyze the Krieg.
Whoever takes the Krieg too high,
he will be hit below.
Comment:
Here learn and know that Liechtenauer strikes an Oberhau (Strike from above) from his shoulder which is called the Zornhau. For someone who is angered and wrathful, no other strike comes as ready as the Zornhau, because this Oberhau strikes from the shoulder to the opponent, and this is why Liechtenauer says: If someone strikes an Oberhau against you, you should strike the Zornhau against him so that your point thrusts forward quickly. If he now defends against your point, pull the sword up and off from his blade and move to the other side of his sword. If he also defends against this, be strong against the sword and wind the point in for the thrust. If he defends this thrust, so take the sword away and strike low to his legs.
So constantly do one after the other thus he may not come to strikes. And always have the already mentioned words, Vor and Nach Indes Schwach Stark and strikes thrusts and cuts, in your mind and never forget these in fencing.
Furthermore, you should not hurry too much in the Krieg because if you aim above and miss so you will hit below. And how you execute one after the other, according to real art with special strikes thrusts and cuts you will hear later.
And you should not strike at someone’s sword but directly to him, to the head or to the body wherever you wish.
