"The action was the first combat in the Italian theatre for the US-Canadian commando unit 1st Special Service Force. They were attached to the U.S. 36th Infantry Division. The 1st SSF used the special training that they had received in winter and mountain warfare to scale the mountain and overcome the Germans atop the stronghold. The cost for both sides was high though. The 1st Special Service Forces suffered a 77% casualty rate, but distinguished themselves by doing the seemingly impossible.
With the rest of 36th Division on 1st SSF's right attacking Monte Maggiore and British 56th Infantry Division (attacking Monte Camino) and British 46th Infantry Division on their left, it took 5 days heavy fighting for the Camino hill mass to be cleared. Casualties were high. After a pause to regroup the U.S. Fifth Army renewed its offensive but it took until mid-January to advance the 10 miles (16 km) to Cassino at the mouth of the Liri valley and the formidable Gustav Line defenses, where the Allies were halted by stubborn German defense until May 1944."
