The first volume in George Macaulay Trevelyan's magnificent classic trilogy traces Garibaldi's life from his early education and training through his life in South America, his return to Italy, his defence of Rome against a French siege and his retreat to the republic of San Marino.

The third volume in the famous trilogy covers Garibaldi's role in the events of June to November 1860, the decisive year in the making of Italy ending with his conquest of Sicily and Naples and his acknowledgement of Victor Emmanuel of Piedmont-Sardinia as king of a united Italy.
