The general’s greatest conquest

Grant's battlefield heroism was matched by the courage to complete his memoirs, pain and pressure be damned, as cancer closed in and the light dimmed. When he finished writing,
he was done.

Equally impressive was his winning battle against alcohol. Twain understood:

"Mark Twain had struggled with similar cravings for alcohol and tobacco. When they discussed the subject, Grant mentioned that although doctors had urged him to sip whiskey or champagne, he could no longer abide the taste of liquor. Twain pondered this statement long and hard. "Had he made a conquest so complete that even the taste of liquor was become an offense?" he wondered. "Or was he so sore over what had been said about his habit that he wanted to persuade others & likewise himself that he hadn't ever even had any taste for it." 95 Similarly, when Grant told Twain that, at the doctors' behest, he had been restricted to one cigar daily, he claimed to have lost the desire to smoke it. "I could understand that feeling," Twain later proclaimed. "He had set out to conquer not the habit but the inclination—the desire. He had gone at the root, not the trunk." 96 Although Twain hated puritanical killjoys who robbed life of its small pleasurable vices, he respected abstinence based on an absence of desire."
