Passage 8.40.4
τότε οὖν ὁ μὲν τὴν πληγὴν ἀφῆκεν ἐς τοῦ Δαμοξένου τὴν κεφαλήν· ὁ δὲ ἀνασχεῖν τὴν χεῖρα ὁ Δαμόξενος ἐκέλευσε τὸν Κρεύγαν, ἀνασχόντος δὲ παίει τοῖς δακτύλοις ὀρθοῖς ὑπὸ τὴν πλευράν, ὑπὸ δὲ ἀκμῆς τε τῶν ὀνύχων καὶ βίας τῆς πληγῆς τὴν χεῖρα ἐς τὸ ἐντὸς καθεὶς καὶ ἐπιλαβόμενος τῶν σπλάγχνων ἐς τὸ ἐκτὸς ἕλκων ἀπέρρηξε.
Then Kreugas delivered his blow upon the head of Damoxenus; but Damoxenus ordered Kreugas to raise his hand, and when he raised it, Damoxenus struck him under the ribs with fingers extended straight. Due to the sharpness of his nails and the force of the blow, he drove his hand inside Kreugas' body, seizing the entrails, which he drew out by violence, causing his opponent’s death.
