The devastation of Indian Territory during the 1861-1865 was overwhelming.
Both sides committed crimes and atrocities. Postbellum official reports, when
found, are intriguing. The following is from the Report of the Commissioer of
Indian Affairs Made ro the Secretary of the Interior for the Year 1869 (1870).

This is a report (No. 130) on pp. 415-416, from Leonard Worcester, Superintendent
Tullahassee Manual Labor School

Tullahassee,C.N., August 3, 1869

" ...... He (Rev. W.S. Robertson) arrived on the ground in December. 1866,
and found the place in a most deplorable condition. The school building had
been used as a hospital and barracks by the troops of armies-part of the
lower rooms used as stables for the horses; door casings and window frames
torn out and used as fuel, and, to complete the work of despoiliation, a large
portion of the brick wall was forn out by the federal troops, and the brick taken
to Fort Gibson to be used in the erection of of a government bakery."

Note: this bakery was not the site of the current reconstruction on at Fort Gibson
Historic site. That reconstruction is on the site of the bakery from the 1866-1868
rebuilding of the fort.
