I have given this about intent and force some thought, and its about context. The norm in todays HEMA is a dueling situation, its how the manuscripts depict things, its how its easiest to train and its how competitions arranged.
In that context, not using the space, going on strong, may not always be the obvious choice. But if you put Lichtenauer in another context, in a real battle, it makes much more sense. If you look at the Lichtenauers fechtbuch in the light of being in the ranks on a battle field, than it makes becomes much more clear that you shall strike as soon as you are within distance, and continuing going for openings, even if you miss the first strike. Cause there is no way but forward as you may have a 1000 men in your back pushing on. There is no backing up, and if you are starting to, you will be dead, there is no space. There is most likley no time either, you need to win ground, you need to be ahead of your opponent. And you will come into grappling distance, cause your opponent will not either have space to back up.
I haven’t studied Meyers longsword that much yet, but it would be interesting to see how it differs. I think I heard that he goes straight to technics and doesnt really go in to the philosophy on the mindset on how to fence. Which also makes sense if its more of a duel fight, you dont need the same mindset as in a battlefield.
