Passage: During the American Civil War (1861–1865), Booth translated the works of eminent French writers in favor of the cause of the Union. In rapid succession appeared translations of: Agénor Gasparin's Uprising of a Great People and America before Europe (New York, 1861), Édouard René de Laboulaye's Paris in America (New York, 1865), and Augustin Cochin's Results of Emancipation and Results of Slavery (Boston, 1862). For this work she received praise and encouragement from U.S. President Abraham Lincoln, U.S. Senator Charles Sumner, and other statesmen. During the entire war she maintained a correspondence with Cochin, Gasparin, Laboulaye, Henri Martin, Charles Forbes René de Montalembert, and other European sympathizers with the Union. At that time, she also translated the Countess de Gasparin's Vesper, Camille, and Human Sorrows, and Count Gasparin's Happiness. Documents forwarded to her by French friends of the Union were translated and published in pamphlets, issued by the Union League Club, or printed in the New York journals. Booth translated Henri Martin's History of France. The two volumes treating of The Age of Louis XIV were issued in 1864, and two others, the last of the seventeen volumes of the original work, in 1866 under the title of The Decline of the French Monarchy. It was intended to follow these with the other volumes from the beginning, but, although she translated two others, the enterprise was abandoned for lack of success, and no more were printed. Her translation of Martin's abridgment of his History of France appeared in 1880. She also translated Laboulaye's Fairy Book, Jean Macé's Fairy Tales and Blaise Pascal's Lettres provinciales (Provincial Letters). The "Uprising of a Great People", was followed rapidly by Gasparin's "America Before Europe," by Laboulaye's "Paris in America," and two volumes by Augustin Cochin, " Results of Emancipation" and "Results of Slavery." Cochin's work attracted even more attention than Gasparin's had done. She received hundreds of appreciative letters from the leading Republican statesman — Henry Winter Davis, Senator Doolittle, Galusha A. Grow, Dr. Lieber, Dr. Bell, the president of the Sanitary Commission, and a host of others, among them George Sumner, Cassius M. Clay, and Attorney-General Speed, Charles Sumner writing her that Cochin's work had been of more value to the cause "than the Numidian cavalry to Hannibal." In the meantime, she pursued her translations as before, adding to her list Laboulaye's "Fairy Tales," and Jean Mace's " Fairy Book," and several of the religious works of the Count and Countess do Gasparin, "Happiness" by the former, and "Camille," " Vesper," and " Human Sorrows " by the latter. Her translations in all number nearly forty volumes. She had thought of adding to this number, at the request of Mr. James T. Fields, an abridgment of George Sand's voluminous "Histoire de ma Vie". Circumstances, however, prevented the completion of the work.
