To break non-stackered Enigma machines, Knox used a system known as rodding, a linguistic as opposed to mathematical way of breaking codes. This technique was applied successfully against the Enigma used by the Italian Navy and the German Abwehr. Rødding is a municipality in south Denmark, in the county of South Jutland on the peninsula of Jutland. ...

Knox met with great applause, as well from the manner in which he delivered a copy of Latin verses, as from the merit of the verses themselves, which (contrary to what usually takes place) were known to have been the speaker’s composition.
Knox accepted the degree of Doctor of Divinity, conferred upon him by a diploma from Philadelphia, without solicitation, in the handsomest manner, as a compliment for the benefit America had derived from his admirable Essays, which had been exceedingly popular in that country.
Knox was rector of Rumwell and Ramsden Crays in Essex (of which livings he was the patron), and minister of the chapelry of Shipbourne in Kent, to which he was presented by the late Viscount Vane.
Knox was one of the British participants in the July 25, 1939, Polish-French-British conference held at the Polish Cipher Bureau facility at Pyry, south of Warsaw, Poland, in which the Poles disclosed to their French and British allies their achievements in Enigma decryption.
Knox was chagrined â" but grateful â" to learn how simple was the solution of the Enigma's entry ring (standard alphabetical order).
