The battle lasted fours days, resulting in a complete defeat of the Swiss Nidwalden troops. Mainoni's horde retaliated heavily, killing and raping the local population. In the German language, there is an expression for these acts: Schreckenstage von Nidwalden which means literally "Horror days of Nidwalden". Mainoni's presence in Nidwalden lasted till the end of October 1798, with widespread negative consequences for the locals. According to Swiss sources, around 100 villages had been burned, many civilians tortured and raped: 435 deaths among which 118 women and 25 children.

Mainoni was then asked to leave Ticino, heading for the Canton Grisons. He was captured, in March 1799, by the Austrians, but his captivity didn't last long. After four months of imprisonment in the Graz Fortress, he was exchanged in August 1799 for the Austrian General Franz Xaver von Auffenberg (1744-1815).
