A bittersweet Civil War story

Errol Morris, in the New York Times, wrote a five-part series on Amos Humiston, a Civil War soldier who died on the battlefield in Gettysburg. Humiston, unknown when his body was found, was clutching a photograph of his three children when he died.

The series, "Whose Father Was He?" looks at the initial history of identifying the fallen soldier (part one).

In part two, Morris interviews Mark Dunkelman, the author of a book about Humiston, including how Dunkelman found the current Humiston descendants.

Next (part three), Morris explores Gettysburg war photography and the attempt to assist the orphaned children of the dead soldiers.

Part four discusses the uneven (to say the least) administration of the orphanage and the enigmatic character who founded it.

Finally, Morris attempts to discover who Amos Humiston was as a person by piecing together all the known information about him (part five).
