 In late April, the 22nd Battalion became the 5th Brigade's main effort, leading the advance towards the Piave River, where they found that all bridges had been destroyed.Improvising, the battalion pressed a local ferry into operation and after establishing a bridgehead on the other side of the river, continued the advance towards Trieste, fighting its final actions of the war against the Germans around Miramare.The battalion lost its final casualties when one of its companies was fired upon by Yugoslav partisans near Opicina after the end of hostilities.
