This threat was real: Russell, in May 1940, travelled to Berlin in an effort to obtain arms and support for the IRA. He received training in German ordnance, but died on a submarine while returning to Ireland as part of Operation Dove. A small number of inadequately prepared German agents were sent to Ireland, but those who did arrive were quickly picked up by the Directorate of Military Intelligence (G2). Active republicans were interned at the Curragh or given prison sentences: six men were hanged under newly legislated acts of treason and three more died on hunger strike. The Germans also later came to realise they had overestimated the abilities of the IRA. By 1943, the IRA had all but ceased to exist. In Ireland, neutrality was popular, despite rationing and economic pressure.
