Ou the outbreak of the insur rection in Lombardy in 184S Radetzky was driven from Milan after five days of desperate fighting and fell back on Verona. His position was for a time precarious, but having received reinforce: ments he was enabled to assume the offensive, and inflicted a crushing defeat on the StIrdinian King Charles Albert at Custozza, July 25, 184S.
A six months' armistice was agreed to, and war was not resumed by the Piedmontese till March, 1S49. Radetzky was this time better prepared, and at once invaded Piedmont. He totally routed the enemy at Novara, March 23, 1849. Peace was concluded with Sardinia, and Radetzky besieged Venice, which surrendered after a long siege (August 23d). He was then appointed Governor-General of Lombardy and Venetia, and ruled with absolute authority till his retirement in February, 1S57. He died at Milan.
