It appears that Abwehr hoped the training of seemingly compliant Irish POW's who had previous military experience with the British Army would lead to success.
He had been captured by the German Army sometime during the period 1940 – April 1941, most likely as part of the British Expeditionary Force active in France and he had been detained in Stalag XX A (301).
At this camp he came into contact with fellow Irishmen, possibly including IRA volunteer Frank Ryan during his recruitment efforts for the Abwehr.
