Pierre Mendes France was a Radical Party leader who was Prime Minister for eight months in 1954–55, working with the support of the Socialist and Communist parties. His top priority was ending the war in Indochina, which had already cost 92,000 dead, 114,000 wounded and 28,000 captured in the wake of the humiliating defeat at the Battle of Dien Bien Phu in early May 1954.
