The following year, the important Battle of Điện Biên Phủ was fought between the Việt Minh (led by General Võ Nguyên Giáp), and the French Union (led by General Henri Navarre, successor to General Raoul Salan). The siege of the French garrison lasted fifty-seven days, from 17:30, 13 March to 17:30, 7 May 1954. The southern outpost or fire base of "Camp Isabelle" did not follow the cease-fire order and fought until 01:00 the following day. The long-scheduled Geneva Meeting's Indochina conference involving the United States, the UK, the French Union and the USSR had already begun on 26 April 1954.
