Albumen print by A Gardner from a negative by Timothy H O'Sullivan, from the album asembled by John Downes Rochfort. Rochfort visited all the major American Civil War sites in 1867 and some of the photographs he purchased en route have since become some of that war's best known images. Up to this time war had been portrayed as a series of heroic tableaux; these photographs revealed its realities for the first time. Little Round Top Hill saw some of the fiercest fighting of the Battle of Gettysburg, the decisive engagement of the war. On 2nd July the Confederate 15th Alabama Regiment were repulsed by the Union 20th Maine Infantry, defending the hill. Defeat at Gettysburg marked the end of General Robert E Lee's planned invasion of the north.
