Ridsdale was undoubtedly an adept in such arrangements as have been hinted at with reference to the clearing of the path for his horse. In that year's Derby there would probably be half-a-dozen horses which might have proved more or less dangerous to St. Giles; but by some means or other--money, in fact--the owners of these animals, or their trainers or jockeys, would be gained over by the confederacy, at a cost, perhaps, for the half-dozen, of some twenty or five-and-twenty thousand pounds. As a matter of course, St. Giles had been used simply as an instrument of gambling; as a two-year-old, his quality as a race-horse had been hidden by his having undoubtedly been "pulled" in his earlier races, so that when the day of his victory arrived, the odds against his chance might be large enough to make it worth the while of his owner to let him run. Margrave, the St. Leger winner, as has been stated, ran fourth in the Derby; but probably that horse was good enough to have won the Epsom trophy, had St. Giles not been on duty; but, had it done so, the odds against its winning the St. Leger would not have been anything like 8 to 1, the price quoted at the start for the great Doncaster trophy. By the success of Margrave another large stake was won by the confederates; the amount has been variously estimated at from forty to ninety thousand pounds. Some time after the decision of this event, a quarrel ensued between the partners, which brought their connection with each other to an end. The affair was somewhat of a _cause célèbre_ in its day, but may be dismissed in a few words. It would appear, from what was made public at the time, that Ridsdale had insinuated he had not received his fair share of the cash won over Margrave, stating that Gully had obtained £12,000 more than he had. Gully, resenting this statement, struck Ridsdale in the hunting-field in a brutal way with his whip; a trial took place at York Assizes, when damages to the extent of £500 were awarded to Ridsdale, who had a large number of sympathisers on his side. The two men, while their association lasted, effected some bold transactions on what may be called the smaller races of the time, putting large sums in their purses by the exercise of their cunning, or, as it would now be termed, "astuteness." The monetary details of those transactions have never been made public in detail, but were estimated at the time from the extent of the settlements of the partners at Tattersall's, where both men, so far as their credit was concerned, were held in high esteem. One of their intended "good things," which did not come off, was Little Red Rover's attempt to win the Derby of 1830, which was won by a celebrated racer called Priam. Had Red Rover won, the confederates would have pocketed between them the better part of £80,000.
