Title: Robert E. Lee
Content:  On September 28, 1870, Lee suffered a stroke. He died two weeks later, shortly after 9 a.m. on October 12, 1870, in Lexington, Virginia, from the effects of pneumonia. According to one account, his last words on the day of his death, were "Tell Hill he must come up! Strike the tent", but this is debatable because of conflicting accounts and because Lee's stroke had resulted in aphasia, possibly rendering him unable to speak. At first no suitable coffin for the body could be located. The muddy roads were too flooded for anyone to get in or out of the town of Lexington. An undertaker had ordered three from Richmond that had reached Lexington, but due to unprecedented flooding from long-continued heavy rains, the caskets were washed down the Maury River. Two neighborhood boys, C.G. Chittum and Robert E. Hillis, found one of the coffins that had been swept ashore. Undamaged, it was used for the General's body, though it was a bit short for him. As a result, Lee was buried without shoes. He was buried underneath Lee Chapel at Washington and Lee University, where his body remains.
