But in the midst of these triumphs a twofold blow was to strike his heart. Ever since leaving India he had maintained an affectionate correspondence with Lady Canning. That cherished friend he was now deprived of to his great sorrow. Her constitution impaired by the climate and by the anxiety which she had suffered during the strain of the Mutiny, Lady Canning fell a victim to an attack of fever. Lord Clyde's last letter to her arrived after her death, and was acknowledged by Lord Canning, who expressed in a few touching words, "how cordially she whom he had lost reciprocated the regard Lord Clyde entertained for her." A few months later Lord Canning himself, on whose constitution, enfeebled by climate, labour, and anxiety, disease had made rapid inroads, died on the day of his arrival in England. Of the many who followed to their grave in Westminster Abbey the remains of the first Viceroy of Queen Victoria's Indian Empire, none mourned him more deeply than did his former Commander-in-Chief, who had been his associate in the triumph of restoring British ascendancy in the East. By the grave of their dead master and friend Clyde and Outram stood arm in arm, both destined at no long interval to be laid in the earth now covering the coffin of their revered Chief. His latest honour was the highest to which a British officer can attain. In an _Extraordinary Gazette_ published on the 9th of November 1862,--the twenty-first anniversary of the birth of the Prince of Wales--it was intimated that the Duke of Cambridge, Sir E. Blakeney, and Lords Gough and Clyde were promoted to the rank of Field-Marshal. If Colin Campbell had served for over forty-six years before attaining the rank of major-general, his subsequent promotion had been exceptionally rapid, since in eight years he had run up through the list of general officers into the highest position of the military service.
