I assume this letter was to William O Wells.
Henry (21yrs) and William Patten, from Branch Co., were in the 11th Mich. Inf., Co.'C'. There were 3 Secklers, Armon M. (21), Ashal G. (27) and George E. (19) from Clarendon in the 4th Mich Cavalry, Co. 'I'. At the time of the letter, the third may previously have died or, most likely, not yet joined the unit.
