In the meantime Augusto Anfossi had been dangerously wounded, and was obliged to abandon the defence; but his place was taken by Luciano Manara, a youth of twenty-four, who led the attack on the Porta Tosa, on the east side of Milan. Arms had now been freely distributed among the insurgents, and a professor of mathematics from Pavia superintended the fortifications and assisted Manara in the attack. For five hours the assault continued, Manara rushing forward at the head of his forces and effecting wonders with his own hand. Recruits from the country districts co-operated from outside the city with the Milanese insurgents within. At last the gate was set on fire, the position was captured, and the name of Porta Tosa was soon afterwards changed to that of Porta Vittoria. The Austrian soldiers had now become heartily tired of the struggle. Radetzky had arranged his troops in so careless a manner that he was unable to supply them properly with food, and sixty Croats surrendered from hunger. Radetzky was now convinced of the uselessness of continuing the struggle; and, though he had just before been threatening to bombard the city, he now decided to abandon it. So, on the evening of the 22nd of March, the glorious Five Days of Milan were brought to an end by the retreat of the Austrians from the city. This rising had for the time being freed the greater part of Lombardy; but there was yet another Italian city under the Austrian rule, which was achieving its own independence in a somewhat different way. The risings in Vienna, Berlin, Prague, and Milan, though they produced many acts of heroism, and some of wise forethought, did not call to the front any man of first-rate political capacity, nor could they be said to centre in any one commanding figure. In Venice, on the other hand, the movement centred from first to last in one man. The imprisonment of Daniel Manin had been the point of interest to Venetians, the typical instance of their grievances; and more than one circumstance tended to strengthen this feeling. Manin's sister had died from the shock of hearing of her brother's arrest; and his wife had organized a petition for his release which had been signed by the Podestà of Venice and ninety-nine other persons of well-known character. His own legal ability had enabled Manin to dwell more forcibly on the points of illegality in his arrest. But when he and his friends urged his claim to be either tried or set free, the authorities pleaded that they could not release him until they heard from Vienna. This answer must have tended still more to mark him out as a victim of that centralizing force which was endeavouring to crush out Italian feeling; while the fact of his descent from the last Doge of Venice added a touch of historic sentiment to the other points of interest in his case. Manin's arrest had been quickly followed by that of Tommaseo, and in any talk among the patriots of Venice the discussion of these arrests was sure to arise.
