During this time the Royal Navy was riven by the feud between the reforming First Sea Lord, Admiral Jackie Fisher and the traditionalist Admiral Charles Beresford and their followers.
While Cradock's position on the issues dividing the navy are not positively known, a passage from Whispers from the Fleet may offer a clue: "... we require – and quickly too – some strong Imperial body of men who will straightway choke the irrepressible utterings of a certain class of individuals who, to their shame, are endeavouring to break down the complete loyalty and good comradeship that now exists in the service between the officers and the men; and who are also willing to commit the heinous crime of trifling with the sacred laws of naval discipline".

He became second-in-command of the Atlantic Fleet on 29 August, hoisting his flag aboard the predreadnought battleship HMS London.
