journalist Ben Robertson reported that at night Dublin was the only city without a blackout between New York and Moscow, and between Lisbon and Sweden and that German bombers often flew overhead to check their bearings using its lights, angering the British. One widespread criticism was that the Germans located Belfast by heading for Dublin and following the railway lines north. In The Blitz: Belfast in the War Years, Brian Barton wrote: "Government Ministers felt with justification, that the Germans were able to use the unblacked out lights in the south to guide them to their targets in the North." Barton insisted that Belfast was "too far north" to use radio guidance. Other writers, such as Tony Gray in The Lost Years state that the Germans did follow their radio guidance beams. Several accounts point out that Belfast, standing at the end of the long inlet of Belfast Lough, would be easily located. Another claim was that the Catholic population in general and the IRA in particular guided the bombers. Barton wrote: "the Catholic population was much more strongly opposed to conscription, was inclined to sympathise with Germany", "...there were suspicions that the Germans were assisted in identifying targets, held by the Unionist population." This view was probably influenced by the decision of the IRA Army Council to support Germany. However they were not in a position to communicate with the Germans, and information recovered from Germany after the war showed that the planning of the blitz was based entirely on German aerial reconnaissance. However on 20 October 1941 the Garda Síochána captured a comprehensive IRA report on captured member Helena Kelly giving a detailed analysis of damage inflicted on Belfast and highlighting prime targets such as Shortt and Harland aircraft factory and RAF Sydenham, describing them as 'the remaining and most outstanding objects of military significance, as yet unblitzed' and suggesting they should be 'bombed by the Luftwaffe as thoroughly as other areas in recent raids' Firemen return south After three days, sometime after 6pm, the fire crews from south of the border began taking up their hoses and ladders to head for home. By then most of the major fires were under control and the firemen from Clydeside and other British cities were arriving. Some had received food, others were famished. All were exhausted. Two of the crews received refreshments in Banbridge; others were entertained in the Ancient
