Chestnut Horse 1914 by St Alwyne (imp.) out of Poinard. Winner of £26,919, including Melbourne Cup carrying 10st. (!) and all the principal long distance weight-for-age races in Australia. ‘Poitrel’ was a very high class stayer. He retired to his owners’ (Messrs. W. and F. A. Moses ‘Arrowfield Stud’) in 1921. Later he relocated to L.K.S. Mackinnon’s Maribyrnong Stud, Melbourne.
‘Poitrel’ was one of the greatest racehorses and sires of the early 20th century. His win in the Melbourne Cup carrying the massive impost of 10st still evokes disbelief in the most hardened of commentators.
