Born in Berlin, Henry was the 13th child of King Frederick William I of Prussia and Princess Sophia Dorothea of Hanover. Henry's conflicts with his older brother, King Frederick II of Prussia, are almost legendary. Although remarkably similar in appearance and personality (both were fond of the arts and French literature, and both were exceptional military commanders) Henry resented being in Frederick's shadow. Nonetheless, he loyally served as one of his brother's top generals throughout Frederick's reign. Henry tended to be less aggressive than the King in battle; although he never won a victory of the scale of Rossbach or Leuthen (two of Frederick's greatest victories), his caution served him well as he was never defeated on the battlefield.
