On September 14, 1862 Lewis received a wound in the left knee by a mini ball at the battle of South Mountain in Maryland (Fox's Gap). Because of this wound, Lewis's left leg was amputated just above the knee at the United States Hospital in Maryland, on or about September 17, 1862. On February 5, 1863, Lewis L. Simpson received a Certificate of Disability for Discharge. Five days later, in Washington, D.C., he applied for a Pension.
Lewis returned home and died in May 1, 1863. There may have been contributory negligence on his part causing the necessity for a second amputation, and consequently the fatal result. There may have been surgical malpractice in the case. Lewis had never married nor were there any children. He was buried in the Methodist church cemetery in Sand Hill, New York, a tiny settlement near Wells Bridge, New York. Both military and pension records exist for Lewis as his mother later applied for his pension.
