A suggestion for future book buying: Fencing/Sword Fighting. Germany has a pretty well developed tradition (though the inital books were aimed at people who already knew the basics, and often more as a memory aid), starting with Liechtenauer for Longsword and Leckküchner for the Langes Messer (one handed sword).
And if you want great swords, there's some italien (and maybe spanish/portuguese? Not sure on that actually) sources for the Montante. Interestingly, a lot of those techniques are intended for bodyguards.
So, why sword books? Because we'll want to finish the advanced greatsword skill, and boosting the training roll would be nice. Especially if we want to then aim for the swording trait, which Boney has said we can get if we keep at it.
