4. Operation Tiger (Slapton Sands Exercise Disaster, 1944)
In April 1944, during a D-Day rehearsal at Slapton Sands, German torpedo boats ambushed and killed upwards of 749 Allied troops. The incident was classified until after the war, with survivors sworn to secrecy. The lack of transparency about the disaster led to missed lessons and unaddressed weaknesses.
