Having negotiated the postwar intrigues of Washington, D. C., Grant was nominated by the Republicans for president and won a close election in l868 – his margin of victory supplied by 300,000 black votes.
His two terms were plagues by economic catastrophes – including a stock market crash, created by manipulators who hoodwinked him and caused widespread corruption culminating in the Credit Mobilier scandal that rocked Congress.
His failure as a businessman, including the demise of his brokerage firm, Grant & Ward, left him nearly bankrupt, and it was only the publication of his successful Personal Memories of U.S. Grant, dictated while he was dying of throat cancer, that kept his family afloat. It was published, at last, by family friend, Mark Twain.
Grant finally succumbed to the disease at Mount McGregor, near Saratoga Springs, in upstate New York in July 1885.
