The First Special Service Force Assault on Monte la DifensaUSASOC History OfficeFORT BRAGG, NC - Today's Army Special Forces groups trace their official lineage from the First Special Service Force (FSSF), an elite American-Canadian commando unit during World War II. Activated, July 20, 1942 at Fort William Henry Harrison, near Helena, Montana, the 3,000-man FSSF contained a mix of American and Canadian volunteers.(1) Trained and equipped for special operations in mountain terrain, the force first saw combat in the mountains of Italy 75 years ago this week.(2) U.S. Army Lieutenant General Mark W. Clark's Fifth Army had been pressing northward against the German defenses since landing at Salerno, September 9, 1943, with the goal of capturing Rome. Fifth Army's approach was blocked by a series of German defensive belts known as the Winter Line. Tough enemy resistance, coupled with rugged terrain, inclement weather, and an inadequate number of Allied troops, slowed the Fifth Army's progress to a crawl. The steep slopes of Monte La Difensa presented a formidable obstacle to the Allied advance. In November 1943, the 7th Infantry Regiment, 3rd Infantry Division tried and failed to seize control of the mountain, despite a valiant ten-day effort. Other 3rd Division units attacked north of La Difensa, but also could not penetrate the stout German defenses. Limited successes along the front were offset by the high casualty rate. November 13, Lt. Gen. Clark called off further offensive operations for the remainder of the month. The FSSF, under the command of Col. Robert T. Frederick, was called on to break the stalemate. His highly-trained force moved into position near the base of Monte La Difiensa under the cover of darkness on the night of December 1-2. The attack began on the afternoon of the next afternoon with a heavy artillery barrage that saturated the German positions with more than 75,000 rounds.(3) The Force's ground assault commenced under cover of darkness, taking a different route from previous attempts on La Difensa. The Force came in from the east side and moved onto the northern shoulder of the mountain.(4) With artillery pinning down the Germans, the Force began the climb up the steep slope, using ropes to ascend the final 500 feet. Reaching the summit shortly before dawn, the battle commenced when an alerted German sentry fired on the Force members crouching among the rocks. A fierce firefight broke out all along the line. Surprise had been achieved. German defenders, expecting an attack to their front, worked feverishly to reorient their machine guns to meet the assault but were unable to mount an effective defense. They evacuated their positions, escaping down the mountain toward Monte Camino or across the northwest saddle towards Monte Remetana. After two hours of hard, often confused, fighting, the Force secured the top of the mountain.(3) They immediately prepared for a German counterattack. The next three days witnessed constant shelling and counter-attacks, made worse by the rain, snow, and freezing temperatures, which hindered resupply and evacuation of the wounded. The Force sustained heavy casualties from German shelling on the mountaintop. Nevertheless, the Force continued to press the attack, dislodging the Germans from nearby Monte Remetana by December 7. The next night the Force was relieved by the 142nd Infantry Regiment, 36th Division. The first phase of the mountain campaign was ended. The Force had pushed the Germans off Monte La Difensa in a matter of hours when the Fifth Army planners had predicted it would take two or three days.(5) The cost to the Force had been heavy: 73 killed, 313 wounded, and 9 missing in action. A further 116 were evacuated due to weather-related injuries and exhaustion. (6) The assault on Monte La Difensa was the first of many combat operations for the FSSF in Italy. It continued to support the larger Allied advance on Rome through the first half of 1944, and was among the very first units to enter the city in June. FSSF support to Fifth Army is an example of Army Special Operations Forces contributing to large-scale combat operations - a tradition that continues today.Note: This modified article originally appeared in Veritas: Journal of Special Operations History 5:2 (2009): 48-63.

However, the Japanese defenders had abandoned the island before the arrival of the invasion force, and therefore Italy would be the FSSF's true 'baptism by fire.'(3) Martin Blumenson, The U.S. Army in World War II, The Mediterranean Theater of Operations: Salerno to Cassino (Washington, D.C.: Office of the Chief of Military History, 1969), 265.(4) Joseph M.
