Tillie Pierce Alleman (1848-1914) was a young girl of 15 and a resident of Gettysburg during the battle of Gettysburg. Her maiden name was Tillie Pierce. During the first day's fighting, Tillie's father, James Pierce, ran a butcher shop in the town. During the first day of fighting at Gettysburg, the Pierces moved Tillie out of the town to a farm, thinking she would be safer there. It turned out that Tillie ended up right behind the Union lines on the second and third day. The farm where she stayed became a field hospital, and this young girl witnessed much suffering and death. Later in life, Mrs. Alleman wrote an account of what she saw, and it is considered a very accurate and excellent first hand source.
