This joint commando force pioneered modern special operations through unprecedented training, daring raids, and psychological warfare that terrorized German forces across multiple theaters. Their legacy shaped contemporary special forces doctrine and proved that small, elite units could achieve strategic impact through superior training, innovative tactics, and unbreakable unit cohesion.
The 1st Special Service Force: Elite Warriors and the Birth of Modern Special Operations in World War II
In the annals of World War II military history, few units captured the imagination and respect of both allies and enemies quite like the 1st Special Service Force. Known to the Germans as the "Black Devils" and to history as the "Devil's Brigade," this elite joint American-Canadian commando unit represented a revolutionary approach to warfare that would influence special operations doctrine for generations. Formed in 1942 as an experimental force designed to conduct raids behind enemy lines, the 1st Special Service Force evolved into one of the most effective and feared units of the war. Their story encompasses not only remarkable military achievements but also groundbreaking international military cooperation, innovative training methods, and tactical innovations that helped define modern special operations. This analysis examines the formation, organization, operations, and lasting legacy of a unit that proved elite forces could achieve objectives far beyond their numerical strength.
The formation of the 1st Special Service Force emerged from the early war period's emphasis on unconventional warfare and special operations. Following Britain's early successes with commando raids by the SAS under the command of the SOE and the growing recognition that traditional military approaches alone would not suffice against the Axis powers, Allied leaders began exploring new forms of warfare that could exploit enemy vulnerabilities and maximize limited resources.
The concept originated with British and American planners who recognized the need for highly trained, versatile units capable of operating in harsh environments and conducting missions that conventional forces could not accomplish. The influence of British commando operations, particularly Lord Louis Mountbatten's Combined Operations Headquarters, provided crucial tactical and organizational precedents for what would become the Force.
The immediate catalyst for the Force's creation was Project Plough, an ambitious plan developed by British inventor Geoffrey Pyke and championed by Lord Mountbatten. The project envisioned using specially designed snow vehicles (called "Weasels") to conduct winter operations against German installations in Norway and Romania. The plan called for highly trained soldiers who could operate these vehicles in extreme conditions while conducting sabotage and reconnaissance missions.
Although Project Plough was eventually abandoned as impractical, the planning process revealed the potential value of elite, specially trained forces capable of operating independently in hostile territory. American and Canadian military leaders recognized that such a unit could serve broader strategic purposes beyond the original Norwegian mission.
The decision to create a joint American-Canadian unit reflected both practical and political considerations. Canada's geographic proximity to potential Arctic operations, combined with Canadian soldiers' reputation for toughness and outdoor skills, made them ideal partners for extreme environment operations. Additionally, the joint nature of the force served diplomatic purposes, strengthening the military alliance between the two North American nations.
The international cooperation required for the Force's creation was unprecedented in American military history. It required extensive coordination between the U.S. War Department, Canadian Department of National Defence, and British Combined Operations Headquarters, establishing protocols for joint command, training, and operations that would influence future coalition warfare.
The 1st Special Service Force was officially activated on July 9, 1942, at Fort William Henry Harrison, Montana. The choice of Montana as the training location reflected the unit's original Arctic mission, providing terrain and climate conditions similar to those expected in Norway. The remote location also offered the security necessary for developing classified techniques and equipment.
Recruitment for the Force emphasized physical fitness, intelligence, and psychological stability rather than traditional military experience. Both American and Canadian volunteers underwent rigorous selection processes that tested not only physical capabilities but also mental resilience and adaptability. The selection criteria included:
Order of Battle and Organizational Structure
The 1st Special Service Force was organized as a unique hybrid unit combining elements of infantry, artillery, engineer, and special operations formations:
Colonel Robert T. Frederick (1942-1944): The Force's only commanding officer, Frederick was a 1928 West Point graduate who had previously served in staff positions but had limited combat experience. Despite initial skepticism about his appointment, Frederick proved to be an exceptional leader who combined strategic vision with personal courage. He participated in front-line operations, was wounded multiple times, and earned the respect of both American and Canadian subordinates. Frederick's leadership style emphasized leading from the front and maintaining close relationships with his men, contributing significantly to the unit's exceptional morale and effectiveness.
Lieutenant Colonel Edwin A. Walker: Deputy commander and Frederick's primary assistant, Walker helped establish the Force's training programs and administrative procedures. His background in airborne operations proved valuable in developing the unit's parachute capabilities.
Lieutenant Colonel Robert W. McQueen: Canadian deputy commander who served as the primary liaison with Canadian forces and government officials. McQueen's diplomatic skills were crucial in managing the complex international aspects of the Force's operations.
Lieutenant Colonel Thomas C. MacWilliam: Operations officer who played a key role in planning the Force's major operations, particularly the Italian campaigns. His tactical expertise in mountain warfare proved invaluable during the Force's combat operations.
Major Robert H. Burhans: Intelligence officer whose work in developing the Force's reconnaissance and intelligence-gathering capabilities was instrumental in their operational success.
Major Jack A. Akehurst: Canadian officer who commanded various battalions and was known for his aggressive leadership style and tactical innovations in small-unit operations.
One of the Force's most remarkable aspects was the successful integration of American and Canadian personnel at all levels. Unlike many Allied units where nationalities were separated by formation, the Force mixed Americans and Canadians within companies and often within squads. This integration required careful attention to:
Administrative Challenges:
Cultural Integration:
Operational Solutions:
The Force's training program at Fort Harrison was revolutionary in its intensity, comprehensiveness, and innovation. The program lasted approximately six months and covered skills far beyond those taught to conventional infantry units.
Physical Conditioning: The physical training program was designed to develop extraordinary endurance, strength, and agility. Daily routines included long-distance marches with full equipment, obstacle courses, hand-to-hand combat training, and specialized conditioning for mountain and cold-weather operations. The training emphasized functional fitness rather than mere physical strength, preparing soldiers for the varied demands of special operations.
Specialized Skills Training:
Tactical Training: The Force developed innovative small-unit tactics that emphasized speed, surprise, and violence of action. Training scenarios included night operations, behind-lines infiltration, and raids against fortified positions. The tactical doctrine stressed independent action by small groups, with extensive cross-training to ensure operational flexibility.
Psychological Training: Understanding that special operations required exceptional mental toughness, the training program included psychological conditioning designed to prepare soldiers for the stress of combat and isolation. This included escape and evasion training, resistance to interrogation, and leadership under extreme stress.
The Force served as a testing ground for new military equipment and weapons systems. Their specialized mission requirements led to the development and adoption of equipment that would later be used throughout the U.S. and Canadian armies.

Combat Operations and Major Campaigns
The Force's first combat deployment came in the Aleutian Islands, where they were assigned to recapture Kiska Island from Japanese forces. This operation, while ultimately an anticlimax due to the prior Japanese evacuation, provided valuable experience in amphibious operations and confirmed the unit's readiness for combat.
The Kiska operation involved:
Although no combat occurred on Kiska, the operation validated the Force's training and demonstrated their ability to conduct complex joint operations. The experience also revealed areas for improvement in equipment and procedures that would prove valuable in subsequent operations.
The Force's reputation was forged during their service in the Italian Campaign, where they conducted some of the most daring and effective operations of the Mediterranean Theater.
Anzio Beachhead Operations The Force arrived at the Anzio beachhead in February 1944, during one of the most challenging periods of the Italian Campaign. The Allied forces were pinned down in a small beachhead, facing constant artillery bombardment and determined German counterattacks.
The Force was initially assigned to hold defensive positions along the right flank of the beachhead, but their aggressive patrolling and raiding activities soon distinguished them from conventional units. Their operations included:
Aggressive Patrolling: The Force conducted nightly patrols deep into German-held territory, gathering intelligence and disrupting enemy operations. These patrols often penetrated several miles behind German lines, capturing prisoners and identifying enemy positions for artillery and air attacks.
Psychological Warfare: The Force developed innovative psychological warfare techniques that terrorized German forces. They left calling cards on dead German soldiers, conducted silent raids that left enemies dead without apparent cause, and used stealth techniques that convinced Germans they faced supernatural enemies. These activities led to the German nickname "Schwarze Teufel" (Black Devils).
Specialized Night Operations: The Force perfected night fighting techniques that gave them significant advantages over German forces. Their training in stealth movement, noise discipline, and night vision allowed them to operate effectively in complete darkness, conducting raids and ambushes that conventional units could not accomplish.
Monte la Difensa and Monte la Remetanea The Force's most famous operation in Italy was the assault on Monte la Difensa and Monte la Remetanea in December 1943. These German-held mountains dominated the approach to the Winter Line and had resisted multiple Allied attacks.
The operation required:
The Force's success in capturing these objectives, which had defied previous Allied attacks, demonstrated their unique capabilities and established their reputation as elite assault troops. The operation showcased their specialized mountain warfare training and proved that well-trained special forces could achieve objectives that conventional forces could not.
The Force participated in Operation Dragoon, the Allied invasion of southern France, where they conducted specialized operations that supported the broader invasion effort.
Hyères Islands Operation The Force's mission was to capture the Hyères Islands (Port-Cros and Levant) off the French Riviera, eliminating German coastal artillery that threatened the main invasion beaches. This operation combined amphibious assault, island warfare, and coordination with naval forces.
The operation demonstrated:
Mainland Operations Following the successful island operations, the Force participated in the rapid advance along the French Riviera, conducting reconnaissance missions and pursuing retreating German forces. Their mobility and aggressive tactics contributed significantly to the speed of the Allied advance.
