As a younger son of the Prince of Wales, there was little expectation that George would become king. He was third in line to the throne, after his father and elder brother, Prince Albert Victor. George was only 17 months younger than Albert Victor, and the two princes were educated together. John Neale Dalton was appointed as their tutor in 1871. Neither Albert Victor nor George excelled intellectually. As their father thought that the navy was "the very best possible training for any boy", in September 1877, when George was 12 years old, both brothers joined the cadet training ship HMS "Britannia" at Dartmouth, Devon.
