On 16 May, soldiers from the Polish II Corps launched one of the final assaults on the German defensive position as part of a twenty-division assault along a twenty-mile front. On 18 May, a Polish flag followed by the British Union Jack were raised over the ruins of Montecassino Abbey.[3] Following this Allied victory, the next German Senger Line collapsed on 25 May. The German defenders were finally driven from their positions, but at a high cost.[4] The capture of Monte Cassino resulted in 55,000 Allied casualties, with German losses being far fewer, estimated at around 20,000 killed and wounded.[5] Emigrated families from the area still retain a strong presence in the surrounding Casalattico townlands.
