Excerpts from Books and Wikipedia
"The Crimean War saw Britain and France attack Russia to restrain the Russian advance into the Balkans; the war degenerated into a long siege of Sevastopol and occasional bloody battles in the vicinity. . . . But through misunderstandings and unclear orders, they charged the wrong guns and achieved little. In the words of Lord Tennyson's famous poem, The Charge of the Light Brigade, 'Someone had blundered.'" [Furtado: 1001 Days]
