Operation Jericho was a low-level World War II bombing raid by Allied aircraft on Amiens Prison in German-occupied France on 18 February 1944. The object of the raid was to free French Resistance and political prisoners, 120 of whom were to be executed the following day.
Mosquito bombers succeeded in breaching the walls and buildings of the prison, as well as destroying guards' barracks. Of the 717 prisoners, 102 were killed, 74 wounded, and 258 escaped, including 79 Resistance and political prisoners.
