Steven's Knoll - Gettysburg

Union artillery on this hill, now topped by a monument to Major General Henry Slocum, defended against the Confederate attack on East Cemetery Hill as darkness fell over the battlefield on the second day. Before the rebels began their charge the bloody day seemed to be ending peacefully, until a shout of "Look! Look at those men!" turned the artillerists to their guns as a rare night attack began.
