The Peacemakers is an 1868 painting by George P.A. Healy.  It depicts the historic March 27, 1865, strategy session by the Union high command on the steamer River Queen during the final days of the American Civil War.  Although he painted it in at least two versions, the largest was destroyed by fire in 1893, and the second sat unknown in storage for decades. Since 1947, it has been in the White House collection.
