The absence of the French fleet from Brest, which led to the supposition that the harbour must be unguarded, seemed to afford an opportunity for an attack in that quarter. An expedition was planned; the forces were intrusted to Talmash, while the Duke of Leeds' son Caermarthen commanded the fleet. It gave occasion for a new act of villany on the part of Marlborough; though the plan was kept a profound secret, he contrived to worm it out, and as had happened once or twice before in his career, he used his knowledge only to lay the details of the plan before James, and to secure the destruction of the English expedition. Vauban, the great French engineer, was sent down to re-fortify the place. Every vantage-ground was crowned with batteries, and into the trap thus laid for him Talmash had rushed headlong to meet his death, in company with 700 English soldiers (June 7, 1694). Marlborough's treachery in this instance was rather personal than political. Talmash alone of the English generals could in any way compete with him, and he knew that at his death or failure William, who it must be recollected did not know the full extent of his treachery, would be obliged to restore him to his command. His treacherous plan succeeded. He was again employed, though so thoroughly mistrusted, that William refused when he went abroad to give the regency to Anne, which he well knew would be but to give it to Marlborough. But the death of Mary, which occurred at the close of the year, while it excited the other Jacobites to action, for a time rendered Marlborough true to William; for it was followed by a reconciliation between the King and the Princess Anne, and Marlborough was now content to wait till the King's death for the completion of his designs. The more earnest Jacobites followed a different course, and it was in the midst of a conspiracy aimed against his life by Fenwick, Charnock, and Porter, that William set out for Flanders (May 1695).
