and capture Casement confided his personal papers to Dr Charles Curry, with whom he had stayed at Riederau on the Ammersee, before he left Germany. He departed with Robert Monteith and Sergeant Daniel Beverley (Bailey) of the Irish Brigade in a submarine, initially the , which developed engine trouble, and then the , shortly after the Aud sailed. According to Monteith, Casement believed the Germans were toying with him from the start and providing inadequate aid that would doom a rising to failure. He wanted to reach Ireland before the shipment of arms and to convince Eoin MacNeill (who he believed was still in control) to cancel the rising. Casement sent John McGoey, a recently arrived Irish-American, through Denmark to Dublin, ostensibly to advise what military aid was coming from Germany and when, but with Casement's orders "to get the Heads in Ireland to call off the rising and merely try to land the arms and distribute them". McGoey did not reach Dublin, nor did his message. His fate was unknown until recently. Evidently abandoning the Irish Nationalist cause, he joined the Royal Navy in 1916, survived the war, and later returned to the United States, where he died in an accident on a building site in 1925. In the early hours of 21 April 1916, three days before the rising began, the German submarine put Casement ashore at Banna Strand in Tralee Bay, County Kerry – the boat used is now in the Imperial War Museum in London. Suffering from a recurrence of the malaria that had plagued him since his days in the Congo, and too weak to travel, he was discovered by a sergeant of the Royal Irish Constabulary at McKenna's Fort, an ancient ring fort in Rahoneen, Ardfert now renamed Casement's Fort. They arrested Casement on charges of high treason, sabotage and espionage against the Crown. He sent word to Dublin about the inadequate German assistance. The Kerry Brigade of the Irish Volunteers might have tried to rescue him over the next three days, but its leadership in Dublin held that not a shot was to be fired in Ireland before the Easter Rising was in train and therefore ordered the Brigade to "do nothing" – a subsequent internal inquiry attached "no blame whatsoever" to the local Volunteers for failing to attempt a rescue. "He was taken to Brixton Prison to be placed under special observation
