fight between the American John C. Heenan and the English Thomas Sayers sponsored by George Wilkes, publisher of Wilkes' Spirit of the Times. A few months later, as artist for The Illustrated London News, he joined Garibaldi in Italy. Nast's cartoons and articles about the Garibaldi military campaign to unify Italy captured the popular imagination in the U.S. In February 1861, he arrived back in New York. In September of that year, he married Sarah Edwards, whom he had met two years earlier. He left the New York Illustrated News to work again, briefly, for Frank Leslie's Illustrated News. In 1862, he became a staff illustrator for Harper's Weekly. In his first years with Harper's, Nast became known especially for compositions that appealed to the sentiment of the viewer. An example is "Christmas Eve" (1862), in which a wreath frames a scene of a soldier's praying wife and sleeping children at home; a second wreath frames the soldier seated by a campfire, gazing longingly at small pictures of his loved ones. One of his most celebrated cartoons was "Compromise with the South" (1864), directed against those in the North who opposed the prosecution of the American Civil War. He was known for drawing battlefields in border and southern states. These attracted great attention, and Nast was referred to by President Abraham Lincoln as "our best recruiting sergeant". After the war, Nast strongly opposed the anti-Reconstruction policy of President Andrew Johnson, whom he depicted in a series of trenchant cartoons that marked "Nast's great beginning in the field of caricature". Style and themes Nast's cartoons frequently had numerous sidebars and panels with intricate subplots to the main cartoon. A Sunday feature could provide hours of entertainment and highlight social causes. After 1870, Nast favored simpler compositions featuring a strong central image. He based his likenesses on photographs. In the early part of his career, Nast used a brush and ink wash technique to draw tonal renderings onto the wood blocks that would be carved into printing blocks by staff engravers. The bold cross-hatching that characterized Nast's mature style resulted from a change in his method that began with a cartoon of June 26, 1869, which Nast drew onto the wood block using a pencil, so that the engraver was guided by Nast's linework. This change of style was influenced by the work of the English illustrator John Tenniel. A recurring theme
