D-day’s secret weapon: how wetland science stopped the Normandy landings from getting bogged down

Beneath the roar of gunfire and the chaos of D-day, an unlikely hero played a vital role — wetland science. Often overlooked amid military strategies and troop movements, the study of mud proved critical to the success of the largest amphibious invasion in history.

Much has been written about the events of June 6 1944 and the extensive planning that led up to Operation Overlord on that pivotal day. The success of the Normandy landings involved expertise from a vast array of military, espionage, engineering and communication groups. My new report explains how scientists with knowledge of sediments and substrate formation, such as peat found in bogs and fens, were also instrumental in the planning and execution of D-day.
