Time was clearly an important factor in the fraud, hence the bills were sent forward in quick succession. Long before they came to maturity the forgers hoped to be well beyond arrest. They had, moreover, sought to destroy all clue. The sums obtained by Bidwell in the name of "Warren" at the Bank of England were lodged at once by drafts to "Horton" another alias, in the Continental Bank. For these cash was obtained in notes; the notes were exchanged by one of the conspirators for gold at the Bank of England and again the same day a second conspirator exchanged the gold for notes. But just as all promised well, the frauds were detected through the carelessness of the forgers. They had omitted to insert the dates in certain bills. The bills were sent as a matter of form to the drawer to have the date added, and the forgery was at once detected. Noyes was seized without difficulty, as it was a part of the scheme that he should act as the dupe, and remain on the spot in London till all the money was obtained. Through Noyes the rest of the conspirators were eventually apprehended. Very little if any of the ill-gotten proceeds, however, was ever recovered. Large sums as they were realized were transmitted to the United States and invested in various American securities, where probably the money still remains. The prisoners, who were committed to Newgate for trial, had undoubtedly the command of large funds while there, and would have readily disbursed it to effect their enlargement. A plot was soon discovered, deep laid, and with many ramifications, by which some of the Newgate warders were to be bribed to allow the prisoners to escape from their cells at night. Certain friends of the prisoners were watched and found to be in communication with these warders, to whom it was said £100 apiece had been given down as the price of their infidelity. Further sums were to have been paid after the escape; and one warder admitted that he was to have £1,000 more paid to him and to be provided with a passage to Australia. The vigilance of the Newgate officials assisted by the city police, completely frustrated this plot. A second was nevertheless set on foot in which the plan of action was changed, and the freedom of the prisoners was to be obtained by means of a rescue from the dock during the trial. An increase of policemen on duty sufficed to prevent any attempt of this kind. Nor were these two abortive efforts all that were planned. A year or two after, when the prisoners were undergoing their life sentences of penal servitude, much uneasiness was caused at one of the convict prisons by information that bribery on a large scale was again at work amongst the officials. But extra precautions and close supervision have so far proved effectual and the prisoners were still in custody after a lapse of ten years.
