This single photograph depicts almost all basic cuts and parries that would have been taught to mounted troopers. At the extreme distance between fencers, no protective gear appears necessary. Given that their field weapons were used at least for this picture, I believe the drill did not involve actual blade contact.
The basic techniques exhibited by the pairs of fencers, examined from the front going back, can be summarized as follows:
1. Right cuts prime, left uses “St. George’s Guard”
2. Right cuts prime, left parries four
3. Right cuts at outside knee, left parries octave
4. Right cuts four, left parries four
