Each regiment was entitled to one chaplain, who normally would have been a commissioned officer. The regimental commander nominated a chaplain as he would any regimental staff officer when a vacancy existed. The War Department then issued the commission which entitled the officer to pay, rations and supplies from the government.

Ministers from home could visit and speak with the troops; these were pastors rather than military chaplains. These were normally short-term volunteers who had to provide for themselves. Of course there were pastors, lay or otherwise, among the trooops who often provided spirtual guidance. One of the lieutenants of an ancestor's company taught two Bible classes during the Atlanta Campaign. He kept a roll of members for each one and published the roll in his memoirs of the war.

Brigade inspection reports include a line in which the inspector was asked to name chaplains available for duty with the name of the command they served.

Here are the memoirs of Chaplain A. D. Betts, 30^th North Carolina Troops:
