Always Sir Arthur lost so much blood that it was marvel he stood on his feet, but he was so full of knighthood that knightly he endured the pain.

In Malory’s chivalric world, physical suffering is treated as a proving-ground for inner virtue. The line contrasts Arthur’s extreme bodily weakness—so much blood loss it is a wonder he can stand—with an almost superhuman moral strength: he is “so full of knighthood” that he bears pain in a “knightly” manner. The phrasing suggests that knighthood is not merely a social rank but an internalized code that governs conduct even at the edge of collapse. Endurance becomes a visible sign of honor, and the king’s capacity to suffer without complaint reinforces the ideal that true leadership and true chivalry are demonstrated under duress.
