In the summer of 1856 Sir Colin was appointed to the post of Inspector-General of Infantry in succession to the Duke of Cambridge, who became Commander-in-Chief of the army on the resignation of Lord Hardinge. In December of that year he was sent to Berlin as the representative of her Majesty, on the errand of presenting to his Royal Highness the Prince of Prussia (afterwards the Emperor William the First) the insignia of the military Grand Cross of the Order of the Bath. During the first half of 1857 he was actively engaged in the official duties of his important position. Beginning with the depôts in the south of England, he then spent some time in his inspections in Ireland, whence he visited Scotland and returned to London in the beginning of June. How retentive was his memory for faces, names, and events, is illustrated by the following incident told on the authority of the gentleman to whom Sir Colin related it. "While," said Campbell, "I was inspecting the depôt at Chichester, I noticed that an old man, evidently an old soldier though in plain clothes, was constantly on the ground and apparently watching my movements. As I was leaving the barrack-yard at the end of the inspection, he came towards me, drew himself up, made the military salute, and with much respect said, 'Sir Colin, may I speak to you? Look at me, sir! do you recollect me?' I looked at him and replied, 'Yes, I do.' 'What is my name?' he asked. I told him. 'Yes, sir; and where did you last see me?' 'In the breach of San Sebastian,' I replied, 'badly wounded by my side.' 'Right, sir!' answered the old soldier. 'I can tell you something more,' I added--'you were No. -- in the front rank of my company.' 'Right, sir!' said the veteran. I was putting my hand into my pocket to make the old man a present, when he stepped forward, laid his hand on my wrist, and said:--'No, sir; that is not what I want; but you will be going to Shorncliffe to inspect the depôt there. I have a son in the Inniskillings quartered at that station, and if you will call him out and tell him that you knew his father, that is what I should wish.'" The anecdote is a typical sample of the kindly and self-respecting relations of the men of the old army with their officers, before the era of short service set in. When Colin Campbell commanded the Ninety-Eighth he knew the face, name, and character of every man in the regiment. When he was Commander-in-Chief in India, which position he was now immediately to attain, he could recognise by name all the Crimean men of his favourite regiment the Ninety-Third Highlanders.
