I'm looking at Bayard's action starting around @2:21 and I'm not sure it was a fleche. Bayard's body movements look more like (at least to me) an attempt to stop-hit Tulen as he's coming forward. The problem for Bayard is that he keeps pulling his arm back to avoid Tulen's disruptive blade actions, but does not maintain the proper distance with his feet. He tries to slip the point past the parry (perhaps he was targeting the arm), but he either misses or his timing is off and his blade gets caught by Tulen's large, powerful parry-6. Once that happens the odds of him remising from that awkward position before Tulen can riposte are very slim.

1'48 it's not octave it's second. 2 hand's positions to protect right upper line : sixte and tierce (6&3), 2 hand's positions to protect right lower lines Octave et second (8&2). 4 supinated and 4 pronated hand positions.You can also add some declinations: fifth, sixth and high septime and inverted fifth

Tulen vs Borel pls!
