Operation Barclay was a World War II deception by the Allies in support of Operation Husky, the Allied invasion of Sicily in July 1943. The goal was to deceive the Axis powers as to the location of the Allies' assault across the Mediterranean and to divert the Axis military command's attention and resources. Operation Barclay used bogus troop movements, radio traffic, recruitment of Greek interpreters, and acquisition of Greek maps to indicate an invasion through the Balkans.
