[1] After Murat was defeated at the Battle of Occhiobello, the Neapolitans stopped their advance and made a defensive line on the Po River.

Murat had entrenched General Ambrosio's division on his right flank northwest of Ferrara, around the villages of Ravale and Casaglia.

On the same day, an Austrian column under the command of General Mohr, attacked a larger Neapolitan force entrenched in Casaglia.

Following severe fighting in the village, the Austrians eventually broke the morale of the defenders and drove the Neapolitans from their positions by the evening.

Mirandola fell the following day to the Austrians without major fighting and Murat was forced to retire from his defensive position, finally pulling his troops back from Ferrara.
