After graduating from West Point in 1844 and serving in the Mexican War, Winfield Scott Hancock (1824-1886) went on to military fame during the Civil War. At the Battle of Gettysburg, he was shot off his horse, but continued to command his Union troops and eventually defeated the Confederate army's attack. He later ran for president in the election of 1880, but lost to James Garfield by 10,000 votes. Hancock was named for another military hero, Winfield Scott, though they are not related to each other.
The inscriptions are minimal. One side of the base has General Hancock's name.
The Library of Congress has this 1905 panoramic postcard by the Rotograph Company showing Pennsylvania Ave. and the Hancock Monument.
And Carol Highsmith took this panoramic view sometime between 1980 and 2006.
A newspaper article describing the dedication of the monument, says that “The statue is an imposing bronze, representing General Hancock on the morning of the last day at Gettysburg, just before he was severely wounded.” A. R. Waud drew this contemporary sketch of Hancock at Gettysburg.
A similar equestrian tribute to Hancock appears on the Battlefield at Gettysburg on Cemetery Hill where Hancock rallied Union forces on July 1, 1861.
The portrait below from a photo “taken in war time or soon after” appeared in The Century in May 1886.
Appleton's Cyclopædia of American Biography gives us this picture of General Hancock as presidential candidate.
