He joined the Phillips Legion's Infantry Battalion as an Assistant Surgeon on June 30th 1862, serving in that capacity until October 1862 and then serving as its surgeon following the late October resignation of the previous surgeon, Dr Connell. His records indicate that he passed the examination for surgeons on January 31st 1862. Dr Moore served as a surgeon until May 27th 1863 when he resigned. His pension application states that he "was dismissed from duty on account of Rheumatism of the heart in the last of year 1863."
He returned to While Plains and spent the rest of his life there practicing medicine. His wife died in June 1869 and he remarried Mary Elizabeth Eley in December of 1869. Dr Moore died on June 10th 1910 from what appears to have been a stroke and was buried with full Masonic honors in the White Plains Baptist Church Cemetery.
The bone saw is the one used by Dr Moore during the war and is still in the possession of his descendants. It bears mute testimony to the horrors of a war fought while medical treatment was still in a very primitive state.
