Pfaus's mission did not include a military component and he was not given authorisation to discuss items of an intelligence nature. In preparation for his mission, Pfaus was to later meet with the officer in charge of Office 1 West, Abwehr II HQ- Hauptmann Friedrich Carl Marwede, codenamed "Dr. Pfalzgraf". On reaching Ireland, the contact Pfaus had been given was a former member of the IRA's 3rd Battalion, Liam Walsh, who was a friend and confidant of Eoin O'Duffy, and then employed at the Italian Legation. Pfaus was unaware at the time of the meeting that the fascist Blueshirts had been ideologically hostile to the IRA, but did secure from Walsh a meeting with an IRA contact. A meeting between Pfaus and IRA representatives took place on 13 February 1939. Pfaus reported that those included in the meeting were Moss Twomey, the new CS. Sean Russell, and Seamus (Jim) O'Donovan. Pfaus found himself unable or unauthorized to answer all the questions of the IRA, so an arrangement to send an IRA representative to Germany for substantive talks was made. Following this meeting Russell decided to send O'Donovan, within one week, as the IRA's representative. Bowyer Bell puts it so:"Russell, elated by the prospect of German arms, ammunition, and money to supplement the thin stream of Clan na Gael aid, decided to entrust the mission to Seamus O'Donovan."
