Mincio (Anc. Mincius), a river of N. Italy, which runs, under the name of Sarca, from the S. extremity of Tyrol into the lake of Garda, at Riva, issues from it at Peschiera, where it takes the name of Mincio, and flowing southward forms the boundary between the provinces of Verona and Mantua; then, past Goito, turning S. E. it expands into a lake, near the E. end of which is the fortress of Mantua; below this it discharges itself into the Po, near Governolo, after a course of more than 40 m. from the lake. It is navigable for barges throughout the greater part of its length. A battle was fought on the banks of the Mincio in 197 B. C, in which the Insu-bres and Oenomani were defeated by the Romans. Bonaparte crossed the Mincio in May, 1796; and the Austrians under Bellegarde were defeated there by Brune, Dec. 25 and 26, 1800, and upward of 4,000 of them taken prisoners. Another victory over the Austrians was achieved there by the French under Eugene Beauharnais, Feb. 8, 1814, after a bloody conflict. In 1859 the Mincio became aixain the theatre of war between the allied Sardinians and French and the Austrians, the latter endeavoring to concentrate their resistance on the line of the river.
After the battle of Sol-ferino (June 24), the allied armies crossed the Mincio into Venetia, and the war was brought to a close by the peace of Villafranca (July 11), by which Lombardy was transferred from Austria to Sardinia, and the upper Mincio became a part of the boundary between the two states. This boundary ceased to exist in 1866, when Venetia was united with Italy.
