On Saturday, February 21, 2026, 39 shells were discovered on the Horizon beach in Lège-Cap-Ferret, Gironde, following the erosion-induced collapse of a blockhouse in January. The maritime prefecture of the Atlantic stated that most of the munitions were unfired and unprimed, but still posed a danger. A bomb disposal operation was conducted by the Brest-based diver-deminers, who destroyed 35 shells on-site in two separate operations, hampered by high tides. Further clarification and security interventions continued on Sunday, February 22, to neutralize any remaining devices.
