Buckshin, in the colours of prominent French owner Daniel Wildenstein, became Sir Henry's first Doncaster Cup winner in 1978, overcoming a series of injuries to add the Prix Du Cadran, the Jockey Club Cup and the Henry II Stakes to his CV. He was partnered by the most successful Doncaster Cup jockey of all time, Joe Mercer.
However, it was the great Le Moss who dominated the Cup for the next two seasons, completing the coveted stayers' triple crown in 1979. Mercer was on board again for both successes, which were supplemented by the great Ardross in 1982.
Sir Henry turned to Lester Piggott that year, but relied on the talents of another weighing room legend, the late Pat Eddery, when Kneller won the cup for Charles St George six years later. The same combination took the Town Moor honours in 1991 when Great Marquess outstayed the field, whilst six-times champion jockey Kieran Fallon was in the plate for the master trainer's seventh and final win in the race in 1997.
