Tagalie was a small, lightly framed grey filly ("more like a greyhound then a racehorse"[2]), bred by her owner, the financier Walter Raphael.
In addition to Tagalie, he sired three other winners of The Derby and through his grandson, Phalaris, he is the direct male-line ancestor of most modern thoroughbreds.
Her meeting with the Ascot Gold Cup winner Prince Palatine in the Eclipse Stakes at Sandown on July 19 was anticipated as the potential "race of the season",[17] but the filly ran poorly and was unplaced.
Once again, there were some attempts to excuse her performance by claiming that she was unsuited by the soft ground,[18] although another view was that her lack of stamina, which had not been truly tested in the Derby,[19] had now been exposed.
In an attempt to redeem her reputation and win an unconventional Triple Crown, Tagalie was sent to Doncaster in September for the St. Leger Stakes, but made no impression in finishing unplaced behind Tracery.
[22] Tagalie produced only four foals, but they included Allenby, by Bayardo, who finished second by half a length to Tetratema in the 2000 Guineas and won the Newmarket Stakes in 1920.
