Excellent find, JB!
If you have half an hour to watch, it's definitely worth the time. The video covers a lot of topics we have discussed here, among those interestingly the peace negotiations initiated by Longstreet and Ord, employing Julia Dent Grant and Louise Garland Longstreet as mediators ... which were put to an end by Grant.
And I liked the fact that in the early stages of their friendship it was Longstreet who dominated the relationship and supported Grant, whereas after the war of course Grant supported Longstreet. That's what friends are for!
