Awarding the Distinguished Service Medal to the FBI director in 1946,Past National Commander Frank Belgrano Jr. said that thanks to Hoover's work, "not one single act of enemy saboteurs or espionage agents was successful. On the first day of World War I, 62 dangerous enemy agents were arrested. Within the first 24 hours of World War II, 1,700 key figures of the enemy's fifth column were taken into custody, and this figure rose to more than 16,000 before the war was over."
