The famous order, "Don't fire until you see the whites of their eyes!" was given during the Battle of Bunker Hill to emphasize the importance of conserving ammunition and ensuring precision in shooting.

Colonel William Prescott instructed the American troops to hold their fire until the British forces were within close range, ensuring that their shots would have the greatest impact. This approach was designed to maximize damage while reducing unnecessary ammunition use, showcasing the discipline and strategic mindset of the colonial forces. The phrase has since become legendary, representing the determination and steadfastness of the Americans in their struggle for independence.
