The area is known today as Intrepid Park, after the code name for Sir William Stephenson, Director of British Security Co-ordination (BSC), who established the program to create the training facility.

[6] Camp X was established December 6, 1941, by the chief of British Security Co-ordination (BSC), Sir William Stephenson, a Canadian from Winnipeg, Manitoba and a close confidant of Winston Churchill and Franklin Delano Roosevelt.

[7] The camp was originally designed to link Britain and the US at a time when the US was forbidden by the Neutrality Act to be directly involved in World War II.

On the day before the attack on Pearl Harbor and America's entry into the war, Camp X had opened for the purpose of training Allied agents from the Special Operations Executive (SOE), Federal Bureau of Investigation (FBI), and American Office of Strategic Services (OSS) intended to be dropped behind enemy lines for clandestine missions as saboteurs and spies.

However, even before the United States entered the war on December 8, 1941, agents from America's intelligence services expressed an interest in sending personnel for training at the soon to be opened Camp X.

[9] Colonel William "Wild Bill" Donovan, war-time head of the OSS, credited Stephenson with teaching Americans about foreign intelligence gathering.

[13] Reports indicate that graduates worked as "secret agents, security personnel, intelligence officers, or psychological warfare experts, serving in clandestine operations".

[18] Gustave Biéler, a Montrealer of Swiss origin, worked with SOE agents and French Resistance in Northern France before the D-Day invasion.

[20][21] After the US entered the war, the OSS operated an "assassination and elimination" training program that was dubbed "the school of mayhem and murder" by George Hunter White.

[15][24] One of the unique features of Camp X was Hydra, a highly sophisticated telecommunications relay station[7] established in May 1942 by engineer Benjamin deForest Bayly.

The camp was an appropriate location for the safe transfer of code due to the topography of the land; it was also an excellent site for picking up radio signals from the United Kingdom.

[26] The Hydra station was valuable for both coding and decoding information in relative safety from the prying ears of German radio observers and Nazi detection.

In August 2016, a hobbyist with a metal detector uncovered a rusty World War II smoke mortar round, triggering a visit from Canadian Forces Base Trenton's bomb disposal team.

[33] The historic plaque erected at Intrepid Park commemorates the school, which taught the techniques of secret warfare, and Hydra, which became an essential communications centre.
