Question: What American Civil War General in the Union Army was compared to a character created by Shakespeare?

full_context: Document 1: Jacob Dolson Cox: Jacob Dolson Cox, (Jr.) (October 27, 1828August 4, 1900) was a statesman, lawyer, Union Army general during the American Civil War, and later a Republican politician from Ohio. He served as the 28th Governor of Ohio and as United States Secretary of the Interior. As Governor of Ohio, Cox sided for a time with President Andrew Johnson's Reconstruction plan and was against African American suffrage in the South, though he supported it in Ohio. Seeing himself caught between Johnson and the Radical Republicans, Cox decided not to run for reelection. He stayed out of politics for a year, though both Sherman and Grant advocated that Cox replace Stanton as Secretary of War as a means of stemming the demands for Johnson's impeachment. But Johnson declined. When Ulysses S. Grant became President he nominated Cox Secretary of Interior and Cox immediately accepted. Secretary of Interior Cox implemented the first civil service reform in a federal government department, including examinations for most clerks. Grant initially supported Cox and civil service reform, creating America's first Civil Service Commission. However, Cox was opposed by Republican Party managers, who ultimately convinced Grant to cease civil service reforms. President Grant and Secretary Cox were at odds over the fraudulent McGarahan Claims and the Dominican Republic annexation treaty. Secretary Cox advocated a lasting, honest, and comprehensive Indian policy legislated by Congress after the Piegan Indian massacre. Cox resigned as Secretary of Interior having been unable to gain Grant's support over civil service reform. Although Cox was a reformer, Grant had believed Cox had overstepped his authority as Secretary of Interior and had undermined his authority as President. In 1872 Cox joined the Liberal Republicans in opposition to Grant's renomination. In 1876 Cox returned to politics and was elected to and served one term as United States Congressman of Ohio. Congressman Cox supported President Hayes's reform efforts, but his term as Congressman was unsuccessful at establishing permanent Civil Service reform. Cox retired and did not return to active politics, using his time to write several books on Civil War campaigns which remain today respected histories and memoirs.

Document 8: Beauvoir (Biloxi, Mississippi): The Beauvoir estate is notable as the historic post-war home (1876-1889) of the former President of the Confederate States of America, Jefferson Davis, (1807/08-1889), (who was also former U.S. Representative, (1845-1846), and more influentially as United States Senator from Mississippi, (1847-1851, 1857-1861) and in between U.S. Secretary of War, (1853-1857), under 14th President Franklin Pierce).

After her husband's death in 1875, the widow, Sarah Ellis Dorsey learned of former Confederate President Jefferson Davis' difficulties. She invited him to visit at the plantation and offered him a cottage near the main house, where he could live and work at his memoirs (""Rise and Fall of the Confederate Government"").

Supported by Congress, Grant implemented Reconstruction, often at odds with President Andrew Johnson. Twice elected president, Grant led the Republicans in their effort to remove the vestiges of Confederate nationalism and slavery, protect African-American citizenship, and support economic prosperity. Although his presidency has often been criticized for multiple administration scandals and for his failure to alleviate the economic depression following the Panic of 1873, he is regarded as a President who performed relatively well in the context of his time and pursued justice for all.
Document 10: Officers Row: Officers Row, a part of the Vancouver National Historic Reserve Historic District, is a congregation of 21 of the former homes of U.S. military officers stationed at the Vancouver Barracks in Vancouver, Washington.

In the 1970s a grassroots campaign to refurbish the dilapidated properties began to appear, and the site was added to the National Register of Historic Places in 1974. In 1980, the U.S. Army declared it a surplus, and it was henceforth deeded to the city for one dollar. A $10.9 million rehabilitation effort proceeded in 1987.

In 1869, Grant sent Babcock on a mission to explore the possibility of annexing the island nation of Santo Domingo to the United States.
