Thanks for this account. During the winter of 1865-66 some of the wooden markers on the Franklin TN battlefield are said to have been used as firewood. Over time others decayed and inscriptions became unreadable. Still more were 'in the way' of post-bellum farm operations or building projects. For that matter the foot and headboards mentioned for this Tennessean probably didn't last a week after Federal soldiers took notice of it.
People seem to believe that every Confederate military command had its own well-supplied corps of stonemasons. The men of the stonemason corps labored long and hard to mark every military burial with carefully inscribed marble headstones all arranged in nice, neat rows. Of course we can't forget the difficulties that must have attended quarrying and transportation of marble slabs to the armies! Perhaps someone will write the much-needed history of the Confederate Stonemason Corps one day.
I suppose such inquiries testify to the power of wishful thinking.
