Yes, I can only imagine how stressful it would be to be far from home and receiving that sort of news! Interestingly, if I remember correctly, the relatives I mentioned who were illiterate and repeatedly leaving without permission but then returning to their regiment were in the 58th. (Some of them, it seems, did eventually stop returning as conditions continued to deteriorate.) I noticed that they never joined Kirk's men, though my folks who left the 64th frequently did.
Does this mean you were able to find the family writings you were looking for?
