"[3] Abwehr officials/agents, Dr. Jupp Hoven, Helmut Clissmann, and dual Abwehr/Foreign Ministry representative Kurt Haller also visited and spoke with Codd to win his allegiance.
Following these approaches, Codd, along with another POW, Fusilier Frank Stringer, agreed to work for the Germans; and he was assigned an Abwehr handler or liaison: Harald Leichtweiss.
[4] Hoven explains that on arrival in Berlin: they were given instruction at the Abwehr training establishment on the Quenzgut, in the improvised manufacture of explosives, incendiaries, and such like.
Around the time of the cancellation of Operation Innkeeper, Codd was arrested in Düsseldorf by the Gestapo and thrown in prison, after sending a letter to an Abwehr official demanding extra pay and privileges and threatening to terminate his agreement.
Codd was given a new mission, this time to Northern Ireland, and was photographed for a passport issued under his new cover name "Jacob Collins".
This consisted of a series of classes and practical exercises in the use and manufacture of explosives and booby traps followed by a light- and heavy-weapons course at Berlin-Zehlendorf.
Rather than being sent on his mission immediately, Codd was tasked with acting as an interpreter for the SD and a group of twelve Arabs also undergoing training.
At the end of May 1944, Codd was again transferred to a new SD espionage school located between The Hague and Scheveningen called "A-Schule West".
Koller was, in fact, an American, William Colepaugh, who had previously engaged in minor missions for the Abwehr in the pre-war period in Latin America.
At this time, Codd was asked if he wanted to join John Amery's collaborator unit the British Free Corps.
[citation needed] The invasion of Normandy in June 1944 made further training for espionage agents unnecessary, as the fight had come home.
In 1948, unable to find a job in post-Emergency Dublin, Codd wrote a letter to the Secretary of the Irish Minister of Defence offering to demonstrate his ability in such areas as "small arms, grenades, patrolling".
