This pension record existed throughout the decades when her name was off the Medal of Honor rolls. It was a small formal acknowledgment — $20 per month was not generous compensation for permanent disability — but it was an acknowledgment that the institution she had served had not entirely forgotten what her service had cost her.
The pension also documents the timeline of Walker’s physical condition. The atrophy was present from 1865 — established as a disability at the time of the first pension payment. It was with her through all the decades of lecturing and writing and advocacy. She was, throughout the post-war period when she was making her most visible public arguments, a woman who had been physically diminished by her wartime service and who was making those arguments with that diminishment as background.
## The Army of the Cumberland in 1863
The specific unit with which Walker served, and the specific campaign context, place her service in one of the most demanding theaters of the Civil War.
The Army of the Cumberland in 1863 was operating in Tennessee and Georgia, in the campaign that culminated in the Battle of Chickamauga in September 1863 and was followed by the siege and eventual relief of Chattanooga. This was a theater of large-scale engagement, complex logistics, difficult terrain, and significant casualties. The 52nd Ohio Infantry, the unit Walker was assigned to, was part of the force operating in this environment.
The medical challenge in this theater was severe. The Army’s medical system had been improving since the disorganized response to First Bull Run in 1861, but the scale of casualties at Chickamauga — roughly 34,600 combined Union and Confederate casualties in two days — overwhelmed any available system. Surgeons operated in improvised facilities under conditions of extreme stress. Field hospitals received more patients than they could manage with available supplies and personnel.
