The Third New York Artillery had been losing men to Yellow Fever, but ample replacements seemed to be available.
From a Seneca County, New York newspaper in October 1864:
An Efficient Recruiting Officer.
Lieut. JOHN STEVENSON, of the 3d N.Y. Artillery, has recently recruited over 250 men for his regiment, mostly from our county. They left Elmira on Saturday last to join the regiment, which is now at Newbern, N.C. Lieut. STEVENSON has been detailed and sent home on two or three different occasions for the purpose of recruiting, and each time obtained a large number of volunteers. He is an active and efficient officer, and is deserving of much praise for his efforts in strengthening the Artillery arm of the service.
