Surgery at Camp Letterman.
The battle brought devastation to the residents of Gettysburg. Every farm field or garden was a graveyard. Churches, public buildings and even private homes were hospitals, filled with wounded soldiers. The Union medical staff that remained were strained to treat so many wounded scattered about the county. To meet the demand, Camp Letterman General Hospital was established east of Gettysburg where all of the wounded were eventually taken to before transport to permanent hospitals in Philadelphia, Baltimore and Washington. Union surgeons worked with members of the U.S Sanitary Commission and Christian Commission to treat and care for the over 20,000 injured Union and Confederate soldiers that passed through the hospital's wards, housed under large tents. By January 1864, the last patients were gone as were the surgeons, guards, nurses, tents and cookhouses. Only a temporary cemetery on the hillside remained as a testament to the courageous battle to save lives that took place at Camp Letterman.
