In January 1944, the division was back on the front line battering the Bernhardt Line defenses. Persevering through bitter fighting along the Mignano Gap, the 34th used goat herds to clear the minefields. The 34th took Monte Trocchio without resistance as the German defenders withdrew to the main prepared defenses of the Gustav Line. On 24 January 1944, during the First Battle of Monte Cassino they pushed across the Gari River into the hills behind and attacked Monastery Hill which dominated the town of Monte Cassino. While they nearly captured the objective, in the end their attacks on the monastery and the town failed. The performance of the 34th Infantry Division in the mountains has been called one of the finest feats of arms carried out by any soldiers during the war. The unit sustained losses of about 80 per cent in the infantry battalions. They were relieved from their positions 11–13 February 1944. Eventually, it took the combined force of five Allied infantry divisions to finish what the 34th nearly accomplished on its own.
