Putting together the advice of folks in the thread, in particular [MENTION=4937]Celebrim[/MENTION], as well as the presentation of fencing schools in Skull & Bones, and my layperson understanding from reading up on them, here's a sample of what I put together for the "English Fence" school of fighting, presumably inspired by DiGrassi, in 5th edition terms.
How does it look to you?
[h3]The Fence[/h3]
The English fencing school is largely based on the teachings of Di Grassi, and compared to Scrimia or Destreza prefers a natural stance and places a greater emphasis on tempo. Followers of this school incorporate unarmed techniques from boxing or wrestling, and favor flashy moves inspired by dueling and prize fights. You learn the following special technique.
Special Technique - Enclosing & Commanding: When you successfuly grapple an opponent you can to choose to either deal unarmed damage each time you win the grapple, or impose disadvantage on the opponent's attacks as long as they are grappled. You only benefit from this tech inquest while wearing light or no armor.
Suggested Feat: Tavern Brawler
Suggested Fighting Style: Two-Weapon Fighting (changed to allow you to perform Two Weapon Fighting with any weapon in your main hand - not just light weapons - and unarmed attacks with the other, and allowing you to apply your ability modifier to damage of your unarmed attack)
Suggested Battlemaster Manuevers: Feinting Attack, Pushing Attack, Tripping Attack
