During Guizot's tenure as foreign minister, he and Lord Aberdeen, the foreign secretary to Sir Robert Peel, carried on well, and thus they secured France and Britain in the entente cordiale. Part of the formation of the entente came about when Guizot secured the transfer of Napoleon's ashes from St. Helena to the French government. The opposition in France denounced Guizot's foreign policy as basely subservient to England. He replied in terms of unmeasured contempt: "You may raise the pile of calumny as high as you will; "vous n'arriverez jamais a la hauteur de mon dédain!"" In 1845 British and French troops fought side by side for the first time in the Anglo-French blockade of the Río de la Plata.
