1956 Devon Loch, then owned by the Queen Mother, slipped and fell within sight of the wining post at the Grand National. But Hill-Dillon had previously owned Devon Loch. Colonel Stephen Hill-Dillon, described as a steward who used to break and sell horses on to England, brought Devon Loch to Navan racecourse for a final exercise session before he was shipped to his new connections. Partnered by chief work-rider Tommy Carey, he was to school almost two circuits but, as he approached the winning post at the end of the first lap, he "seizes in full stride and sprawls helplessly". Hill-Dillon and Carey, among the small number to witness the incident, are dead. The identity of the vet, whose subsequent examination of Devon Loch was "inconclusive", has not been established, but Carey confided in his family and close friend Tony Raleigh, 62, from County Meath, who has now come forward.

1981 Mar 12. He died. his address then was Glebe House, Fethard, Tipperary
