CUSTOZZA, BATTLE OF.--Fought Sunday, 24th June, 1866 between the Austrians and Italians. “The Italian army, divided into three corps and a reserve, making up a force of from 80,000 to 90,000 combatants, after crossing the Mincio at Gotto, and on the other points, on Saturday afternoon, June 23rd, 1866, and sending reconnoitering parties towards Peschiera and Verona, encamped for the night at some place beyond Roverbella, equidistant from the two fortresses. On the ensuing morning an attempt was made upon those high positions of Sona, Somma Campaigna, and Santa Ciustina, which commands the fifteen miles railway line joining the two strongholds, positions which played a conspicuous part in the campaign of 1848. The object of the Italians was evidently to take possession of the railway, so as to isolate Peschiera and secure a basis of operations against Verona. The Austrians, however, who were massed in great force at Verona, sallied forth from that place at daybreak, and, anticipating the Italian movements, took up their position upon those hills, which are now everywhere bristling with bastions and redoubts, and may be looked upon as mere outworks of the two citadels, extending from the gates of one to those of the other. After a severe and bloody, or, as the Italians describe it, “desperate struggle,” which lasted nearly the whole day--that longest of summer days--the Imperial army was victorious along the whole line. They stormed the summit of Montevente, where the Italians held out the longest, and at the close of the engagement, at five o’clock in the afternoon, they also carried the position of Custozza, a spot fatal to Italian arms in their encounter with Radetski, in July, 1848. The victors captured several guns, and about 2000 prisoners, and behaved, as the Archduke Albert’s bulletin assures us, and as we may readily believe, with even more than their ordinary bravery and endurance. On the same evening the Italian army was obliged to re-cross the Mincio. The Italian accounts of the engagement present no points of material difference. According to them, the first army corps was sent forward to occupy some positions between Peschiera and Verona, but being surrounded by superior numbers, it “failed to effect its purpose,” and the description given of its losses in the contest leaves us little doubt that it was all but annihilated. The second and third corps, unable--it is not said for what reason--to advance to its rescue, were still in the evening “almost intact.” It was also stated from Brescia that the army had maintained its position; but there is little doubt that it had to withdraw across the Mincio later in the night. The Italians had several of their Generals wounded, among others the King’s second son, Prince Amadeus, who has arrived at Brescia.
