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

<P0-S0> Robert E. Lee: Civil War General is a 1996 computer wargame developed by Impressions Games and published by Sierra On-Line. <P0-S1>  Set during the American Civil War, it tasks the player with leading the Confederate Army of Northern Virginia to victory against the Union Army of the Potomac. <P0-S2>  Impressions sought to make "Civil War General" accessible to wargame newcomers by streamlining its gameplay, and the "Panzer General" series was a reference point for its design and title. <SEP> <P1-S0> Iago is a fictional character in Shakespeare's "Othello" (c. 1601–1604). <P1-S1>  Iago is the play's main antagonist, and Othello's standard bearer. <P1-S2>  He is the husband of Emilia, who is in turn the attendant of Othello's wife Desdemona. <P1-S3>  Iago hates Othello and devises a plan to destroy him by making him believe that his wife is having an affair with his lieutenant, Michael Cassio. <SEP> <P2-S0> Orville Elias Babcock (December 25, 1835 – June 2, 1884) was an American Civil War General in the Union Army. <P2-S1>  He graduated third in his class at the United States Military Academy at West Point in 1861, and served in the United States Army Corps of Engineers throughout the Civil War. <P2-S2>  As Assistant Engineer and aide-de-camp for district commander Nathaniel P. Banks, in 1862 Babock worked on fortifications to aid in defending the nation's capitol from Confederate attack. <P2-S3>  Babcock later served as aide-de-camp for Ulysses S. Grant and participated in the Overland Campaign. <P2-S4>  He was promoted to Brevet Brigadier General in 1865 and continued on Grant's staff during Reconstruction. <P2-S5>  After Grant became President in 1869, Babcock was appointed Superintendent of Public Buildings and Grounds for Washington, DC and Secretary to the President of the United States—in modern terms, the chief of staff—and he served in both posts until 1876. <P2-S6>  Upon his appointment Babcock was young and ambitious, and considered the Iago of the Grant administration. <P2-S7>  In 1869, Grant sent Babcock on a mission to explore the possibility of annexing the island nation of Santo Domingo to the United States. <SEP> <P3-S0> The "Grand Army of the Republic" (GAR) was a fraternal organization composed of veterans of the Union Army (United States Army), Union Navy (U.S. Navy), Marines and the U.S. Revenue Cutter Service who served in the American Civil War for the Northern/Federal forces. <P3-S1>  Founded in 1866 in Decatur, Illinois, and growing to include hundreds of posts (local community units) across the nation (predominately in the North, but also a few in the South and West), it was dissolved in 1956 at the death of its last member, Albert Woolson (1850–1956) of Duluth, Minnesota. <P3-S2>  Linking men through their experience of the war, the G.A.R. became among the first organized advocacy groups in American politics, supporting voting rights for black veterans, promoting patriotic education, helping to make Memorial Day a national holiday, lobbying the United States Congress to establish regular veterans' pensions, and supporting Republican political candidates. <P3-S3>  Its peak membership, at more than 490,000, was in 1890, a high point of various Civil War commemorative and monument dedication ceremonies. <P3-S4>  It was succeeded by the Sons of Union Veterans of the Civil War (SUVCW), composed of male descendants of Union Army and Union Navy veterans.
