His reason for retiring from the command of the army was founded on the peculiar circumstances of his dispute with Mr. Canning. “No political opinions would have prevented him,” he said, “under ordinary circumstances, from continuing either at the Horse Guards or at the head of the army in the field; but, from the tone and tenor of the communication he had received from his majesty; from the nature of the invitation to join the administration, contained in Mr. Canning’s post letter, and from the contents of the last letter he received from Mr. Canning, by his majesty’s commands, he saw it would be impossible to continue his relations with that gentlemen, either with service to the country or credit to himself. His resolution had been adopted after the most mature deliberation.”
The foregoing is the substance of the Duke of Wellington’s explanation of his own share in the general resignation of the chief members of Lord Liverpool’s cabinet.
Another circumstance occurred a few days afterwards, which still further increased the public belief that there was a serious quarrel between the Duke and the new premier. The former moved an amendment in committee on the corn bill, which had the effect of defeating the new government on that measure. This was regarded as an act of hostility on the part of the Duke, and, shortly after, a correspondence was made public between him and Mr. Huskisson, then President of the Board of Trade, in which it appeared clear that the Duke had moved the amendment in the belief that the government had agreed to it through Mr. Huskisson, and equally clear that the Duke had been mistaken. There were not wanting those who asserted roundly that the Duke had taken advantage of an ambiguity in Mr. Huskisson’s letters, in order to have a pretext for inflicting this injury on the government. And, unhappily, Mr. Canning himself, carried out of parliamentary decorum by an irritability of temper, springing from the difficulties of his position and from his advancing illness, went so far as publicly to declare that the Duke of Wellington, great man as he was, had been but in instrument in the hands of others. History, he said, afforded parallel the actions of other great men.
The Duke maintained a dignified silence with respect to this attack; but, in the following year, long after Mr. Canning’s death, and when he had himself become prime minister, he took an opportunity of disclaiming, in strong language, the existance of any personal hostility on his part to the deceased statesman.
