earlier we saw the haunting civil war photography show at the met. the highlight was a series of over 30 3d photos which one can see through a 19th century 3d viewer.
there was a picture of lincoln and general mcclellan during a tense battlefield meeting under the eaves of a tent. seeing it in stereoscopic photography gave the eerie feeling of being almost actually present at the scene. a voyeur peeking under the tent flaps, witnessing their famously strained rapport.
two great civil war books: the killer angels by michael shaara, and the personal memoirs ulysses s grant.
