On arrival at Killarney the group transferred into two motor vehicles. Denis Daly drove the first car with Colm O'Lochlainn, Thomas McInerney drove the second car carrying Con, Charlie, and Donal. Since Denis knew the route, McInerney was to follow his tail-lights. However, as is often the case in life, plans began to unravel when a breakdown and a curious RIC officer held up the lead car. Somehow the second vehicle lost sight of the second car, just outside Killorglin McInerney asked a young girl for directions to Cahirciveen. She told them to take the first turn on the right, not knowing the road Thomas mistook the turn leading to the quay. In the darkness he only realised his mistake when the two front wheels of the car went over the unprotected edge into the River Laune, which is deep and wide at this point. It is said that in the moonlight, the reflection of the water resembled a continuance of the road, and having been there I can confirm that the pier is extraordinarily continuous to the road. In the ensuing panic the car became unbalanced and fell into the River with its four passengers still on board. Totally disoriented Thomas McInerney started to swim heading in the wrong direction, only for the intervention of local man Thady O'Sullivan, who guided him back to the shore. At this stage it was clear that the three other occupants of the car had somehow become trapped in the vehicle, and had sadly in all likelihood quickly drowned.Other local people among them Patrick Begley and his son Michael, an Irish teacher based in Limerick had made strenuous efforts to rescue them, but this proved impossible. Cold and disheartened, the one survivor and the rescuers gathered in the O'Sullivan's kitchen. McInerney was advised to go to the RIC barracks and report the incident. Whilst away, McInerneys wet overcoat was picked up, and a revolver was discovered in it, Patrick Begley soon realised that there was more to the nights events than at first thought. At that moment the RIC arrived at the cottage, Begley hid the revolver by sitting on it under a cushion, . The RIC had arrested a man in Tralee, and were alert to the possibility of some Fenian related activity in the area. McInerney stuck to his story that he had been driving tourists around Kerry, and that he did not know the occupants of the car personally. On a wet Holy Saturday morning the bodies of Con Keating and and Donal Sheehan were located by fishermen, no trace of Charlie Monaghan was found until October, some six months later, when his body was discovered on an island in the River. That same morning McInerney tried to retrieve his revolver from Patrick Begley, but Begley said that if the RIC returned it would be better if he was not carrying a weapon. As predicted, they did indeed return and arrested Thomas McInerney, he was transferred after the Rising was suppressed to to the prison camp in North Wales, Frongoch, which was to be the destination of the bulk of those Republicans captured after the Rising. McInerney on release from Frongoch rejoined the IRA and was later killed in County Tipperary.
What we will never know is what would have happened if the unit had succeeded in their mission. Would they have managed to divert the British navy, if they had succeeded in this, then landing the weaponry at Banna would have had a greater chance of success. However to be fair, the arrest of Austin Stack in Tralee would have made distribution well nigh impossible, since he was the key link between the Aud and the local Irish Republican Brotherhood organisation. Nevertheless it is an interesting and little told tale, which is moving for the fact that it illustrates the way in which human error often plays a significant part in determining historical events.
