This article examines the origins of human shielding—the practice of employing hostages on the battlefield—in Arab Palestine during the Great Revolt in the 1930s. The Palestinian rebellion vexed the British for over three years, and during its second phase (1937–1939), lightly armed rebels beat back the colonial authorities from broad stretches of the country, putting continued colonial control of the territory in serious jeopardy. Britain only defeated the insurgency through a harsh repertoire of collective punishments and “dirty war” tactics. British forces used Palestinians as human shields in a systematic fashion during the revolt's second phase, attempting thereby to stave off the insurgents’ consistent and effective attacks on transportation arteries. Beyond its battlefield rationale, this article contends that human shielding was critically tied to two other dynamic processes. The military's adoption of unauthorized tactics like human shielding was part of a broader pattern of rejecting its institutional subordination to civilian authorities and of seeking direct control over the Palestine government in order to assure its unfettered command over the revolt's suppression. At the same time, the conversion of colonized bodies into literal shields bespoke a process of deepening, corporeal racialization that had profound consequences for the Palestinians, stripping them of any figment of legal rights or protections and signaling the utter disposability of Arab life.
