On August 25, 1982, U.S. President Ronald Reagan ordered the deployment of U.S. Marines to Beirut, Lebanon, amid the Lebanese Civil War. The troops were part of a multinational force that stayed in Lebanon until March 1984, resulting in the deaths of more than 260 U.S. service members, with most fatalities occurring during a barracks bombing in October 1983. This deployment was one of several significant events to occur on this date in history, including Galileo Galilei's first public exhibition of his telescope in Venice (1609) and the founding of New Orleans (1718).
