Poule d'Essai des Poulains
The working relationship between Semblat and Boussac eventually deteriorated and in 1954 the trainer was dismissed and replaced by Charlie Elliott, the man he had supplanted fourteen years earlier. Semblat continued to train horses, but with less success, recording his last major win when Thymus took the Poule d'Essai des Poulains in 1959.
