Leech

A doctor, named for the practice of treating patients by bleeding them with leeches.

"The other half of the sword-hilt and the blade were bent, but not severed; and these, I believe, tore off my hand betwixt the gauntlet and the arm-piece: my arm was shattered behind and before. When I marked now that my hand hung loose by the skin, and that my spear lay under my horse's feet, I made as though nothing had befallen me, turned my horse softly round, and, in spite of all, came back to my own folk without let or hindrance from the enemy. Just then there came up an old spearman, who would have ridden into the thick of the fray: him I called to me, and besought that he would stay at my side, since he must see how matters stood with me. So he tarried with me at my prayer, and then he must needs fetch me the leech. When I came to Landshut, my old comrades told me who had fought in the battle against me, and in what wise I had been shot, and that a nobleman, Fabian von Wallsdorf, a Voigtlaender, had been struck and slain by the same shot, notwithstanding that it had struck me first; so that in this wise both friend and foe took harm alike. This nobleman was a fair and goodly gentleman, such that among many thousands you would scarce find any goodlier to behold...."
