I have read prior related posts and looked at the US Army regulations for 1861 and I still am not clear on this. I'm looking at two Captains who were brought to civilwartalk by @MajMarionPatterson, they are Marion Patterson, Capt. of a company of the 19th USC Inf and Enos B Wood, Capt of a company of the 2ND USC Cav. Our member has a file of records concerning Enos B Wood's service, which include some muster rolls he signed as Capt. They are pretty complicated in that they contain pay owed and received by the soldier and roll call information, dates of enlistmrnt, muster in and pertinent remarks. Am I correct that the Captains did not have adjutants to help them with paperwork? Were the Captains responsible for all company reports containing such matters as duty assignments, presence or absence, any illness, infractions or discipline etc.? I assume the Civil War Captain could be assisted by his Lieutenants. Was the level of literacy and education of Captains and Lieutenants required to be high enough to perform such writing and record keeping with accuracy? How much of their time was involved in this kind of thing? If you know of a general description of Captain's duties in the Union Army, I would appreciate a citation. Thank you all for your patience and continuous help with elementary questions.
