Lee's specialty in life was gunnery. At the age of 19 in 1907 "he became the only American to win both the US National High Power Rifle and Pistol championships in the same year." In 1914 during the Veracruz campaign in Mexico he drew the fire of three enemy snipers, thereby exposing their positions and then shot them at long range. He understood the powerful guns of a battleship as an extension of the law of ballistics and adapted his expertise to the new age of technology. When Admiral Lee engaged the Japanese Vice Admiral Nobutake Kondō's battleship on the evening of 14 November 1942 in the waters off Guadalcanal, he became naval history's first battleship commander to conduct a "gunfight" primarily by radar remote control.
