Once an individual had his name drawn and was conscripted into military service what determined when he reported and what unit he became a part of. For example my great grandfather George Himes name was drawn Aug 23, 1863 in Huntington, Pennsylvania. George lived in Taylor Township, Blair county. I have records he served in the 186th Pennsylvania Volunteer, Company G that mustered in Philadelphia, from the 29th of January, to the 31st of May, 1864. How did he get in this company?
