WASHINGTON (AP) — The National Portrait Gallery is continuing a commemoration of the 150th anniversary of the Civil War with a new exhibit focusing on the two generals who led Confederate and Union troops into battle.

The museum opened its latest “One Life” exhibit series last week with a gallery devoted to Ulysses S. Grant and Robert E. Lee. It will be on view through May 2015.

The show uses images mostly from the National Portrait Gallery collection, including photographs, documentary drawings and artist renderings of important events during the final year of the war. It also includes the death mask of each man’s face. A key painting is Winslow Homer’s “Skirmish in the Wilderness” from Connecticut’s New Britain Museum of American Art.

The Civil War was fought from 1861 to 1865.
