"M9", so named as it was the ninth monitor laid down for the Royal Navy, was originally intended to be named simply "Wolfe" after the victor of the Battle of the Plains of Abraham, James Wolfe. On 15 February 1915 she was renamed "Sir James Wolfe" before receiving the name she would be launched under, "General Wolfe", on 8 March. In common with all her sister-ships, which were named for famous British soldiers, the title was most often dropped leaving the name only, hence "Wolfe".
