Sir Matthew lunged, his sword was caught, carried out to the left, and held there as Sir Seymour's blade slid inward along it.

Just in time, Sir Matthew's inward pressure carried Sir Seymour's sword clear to the right again.

Sir Matthew disengaged over, and, as the sudden release brought Sir Seymour's sword springing in, he thrust under that gentleman's right arm and scratched his side.
As he recovered his sword he held it for a moment with the point raised toward Sir Seymour's face.

Instantly Sir Seymour's point tinkled on his hilt, and Captain Delorme murmured "Finis" beneath his breath.
Sir Stukeley Seymour's blade shot in, Sir Matthew's moved to parry, and the point of the advancing sword flickered under his hand, turned upward, and pierced his heart.
"Yes," said Captain Delorme, as the stricken man fell, "if he parries outward the point goes under, if he anticipates a feint it comes straight in, and if he parries a lunge-and-feint-under, he gets feint-over before he can come up.

I have never seen Stukeley miss when once he rests on the hilt.
