Having evacuated Milan after the Five Days of Milan on 22 March 1848, field marshal Radetzky regrouped his forces in the Quadrilatero, composed of the four supporting fortresses of Peschiera, Mantua, Verona and Legnago. The Piedmontese army advanced across Lombardy, brushing aside the covering forces under major general Wohlgemuth guarding the bridge over the Mincio at Goito during an engagement on 9 April 1848. The Austrians tried but failed to destroy the Goito bridge. Once across the Mincio, the Piedmontese forces fanned out towards the north and south.
