In September 1944, the 4th Parachute Division was defending positions at the Futa and 2 Giogo Passes when the U.S. 91st and 85th divisions mounted an attack.[52] This was followed by six days of intense fighting.[52] American forces succeeded in capturing the 2nd Giogo Pass, Monticelli Ridge, and Monte Altuzzo, in Italy, mostly due to the overwhelming firepower of American forces.[52]
