Wartime Letter Raises Question

My family left North Carolina for Alberta, Canada, in 1904, so little is known about my great-great-grandfather William Cheek’s Confederate service. Born in Ashe County Apr. 14, 1844, he enlisted in Co. I, 61st North Carolina Infantry in Alleghany County in 1862. He reportedly was captured at Petersburg, Va. in July of 1862, but the letter below is dated May 27, 1864. Could he have been part of a prisoner exchange and rejoined the war? He survived the war but died Dec. 19, 1873, at age 29. Peters Burg VA. May the 27/64 Gilly Cheek Lucinda Cheek I thy morning seat myself to drop you a few lines.
