This quarrel between the two sections of the national party in Milan tended to strengthen the power of Charles Albert. Casati had originally felt little sympathy for the Piedmontese aristocracy; but his growing distrust of Milanese feeling strengthened the effect produced by the victory at Goito, and the capture of Peschiera, and induced him to rest his hopes for the success of the struggle against Austria solely on Charles Albert, and the Sardinian army. And while the divisions in Milan strengthened Charles Albert's power in Lombardy, the weakness of the cities of Venetia, though due to a large extent to the previous vacillation of Charles Albert, was yet compelling them more and more to appeal to him as the recognised leader of the most important Italian force in the North of Italy. This tendency had been resisted by Daniel Manin, who was strongly opposed to the fusion of Venetia with Piedmont; and when he found that Charles Albert was unwilling to help the Venetians on any other terms, he had been disposed to turn for help rather to France than to Piedmont. But the prestige of Charles Albert's victories in Lombardy were attracting Vicenza and Padua to the scheme of fusion; and nothing but the proof that Venice could save Vicenza could counteract this tendency. Manin and Tommaseo felt so much the importance of this point, that they even left Venice for a few days to go to the help of Vicenza; and the coldness of Charles Albert towards the defence might, if Vicenza had held out, have worked in favour of Manin's views. But Radetzky also saw the importance of this siege, and resolved to lead the attack in person. He appeared before the city on June 9, and on the following day succeeded, after a fierce struggle, in occupying the heights which surrounded it. The defence speedily became hopeless; and, though Durando was afterwards blamed for the surrender, and even suspected of treason, there seems little reason to suppose that the town could have obtained better terms than those which were now granted it, if it had attempted a longer resistance. The garrison was allowed to go out with arms and baggage; the lives and property of the inhabitants were to be safe; and a full amnesty was to be granted for the past; the garrison only binding themselves not to bear arms for three months. The fall of Vicenza seemed to mark the crisis of the struggle in Venetia. Padua, Treviso, and Palmanuova rapidly fell into the hands of the Austrians; and the citizens of Venice now began to believe that, so far from being able to defend the freedom of their countrymen, they could only hope to secure their own freedom by surrendering themselves to Charles Albert.
