I'm trying to add a quote from the above book but the system won't let it go through and won't give a reason. Could someone else try to add this quote?:

Ironically, Meade won the campaign but lost the trust of his commander-in-chief, while Lee lost the campaign but Davis continued to hold him in high esteem. Lingering health concerns, however, including likely bouts of angina pectoris (heart problems), convinced Lee that he was no longer able to satisfy the rigorous demands of running an army in the field. His stamina was waning. Lee tended his resignation after Gettysburg, but Davis would have none of it. Who else could possibly command the Army of Northern Virginia as well as even a weakened Lee?

I just tried it again and it "went through" this time.
