I'm guessing this accusation carried over from the morning of the infamous breakfast conference! Nobody who was there lived to tell what was really said except Forrest and Cheatham, and they didn't say anything about it. The conversation is in the 'legend' category - nobody seems to be able to find a real source for anything supposed to have been said. Mrs Peters was a young woman married to a much older man and that's always a bit of trouble. Cheatham definitely liked a taste or two. According to the legend, it wasn't Cleburne Hood accused of carousing but Forrest. Which brought about Forrest's allegedly saying, "If you were a whole man I'd whip you to within an inch of your life." What is known is Forrest was furious when he left the conference and Cleburne was much hurt, possibly costing him his life later that afternoon. Hood did feel that somebody was drunk and I can't help but sympathize a little with him considering the incomprehensible way Schofield slid on by.
First, I'm glad you addressed the "Breakfast meeting."
Just as you say - "nobody seems to be able to find a real source for anything supposed to have been said."
There is clearly a reason why. Hood of course blamed Cheatham in the days following the event, and especially in his autobiography. He was in great need of corroborating testimony regarding many of his accusations regarding most everything, and be sure - if he had anyone that would have corroborated 'chewing out his corps commanders' at Rippavilla, he certainly would have included testimony from that person. He doesn't mention it in his autobiography at all though.
Cheatham and Forrest probably didn't mention it because - it likely never really happened.
I have searched long and hard for facts regarding that meeting. Other than complete supposition, there is only one
oral account of the meeting. Mrs. Cheairs supposedly gave them breakfast, and heard Hood's tone and could recognize the anger in his voice. Mrs. Cheairs never identified who was at the meeting, but in light of absolutely no evidence of any of the commanders other than Hood being there, I suspect he was ranting and raving to his staff - talking **** about the failure of Cheatham, Stewart and Forrest.
Second, Hood never actually accused anyone of drunkenness. Again, you can be sure that that would have been included in his autobiography. Hood was face to face with all his corps commanders at different points that night. He would have known- and so would many others - if one of them was drunk.
All the evidence merely points to the simple fact that plans don't always unfold the way they are intended to. No one is blameless for the failure there, that goes for ALL the corps commanders, CO and even Forrest!
