Apparently an officer in the New York 33d Volunteer Infantry took advantage of a winter break in the action to visit home.
From a Seneca County, New York newspaper in March 1863:
Personal.
Capt. MCGRAW, of the 33d Regiment arrived home on Wednesday on a brief furlough of ten days. His numerous friends were glad to see him looking so well, after his long absence in the service of his country. He represents his command, and the regiment, in good spirits and condition.
We were also pleased to see Capt. J.C. PETERSON, of the 15th U.S. Infantry, who made his appearance in town during the past week. Capt. PETERSON is now attached Gen. ROSENCRAN’s staff as Assistant Inspector General, and has borne a prominent part in the campaigns in Kentucky and Tennessee. He is home for the purpose of recruiting his health.
