Sharpshooter President's Target Board
There were dark days in the early years of the Civil War, when it appeared as if wily Confederate generals might mount an assault on Washington DC itself. President Lincoln vowed to stay, and might have even been useful picking off Johnny Rebs as they crossed the Potomac.
This target board shows the ballistic accuracy of the Commander-in-Chief on August 18, 1863; standing on the White House lawn, Lincoln fired seven consecutive shots with a Spencer rifle from a distance of 40 yards. It's displayed at the Illinois State Military Museum, where you can also see Santa Anna's captured wooden leg.
