In 1948, shortly before the State of Israel declared its independence, Yadin, interrupted his university studies to return to active service. He served as Israel's Head of Operations during the 1948 Arab-Israeli War, and was responsible for many of the key decisions made during the course of that war. In June 1948 he threatened to resign during the Generals' Revolt during which he accused Ben-Gurion of attempting "to transform the army as a whole into an army of one political party (Mapai)".
