Grant's presidency was marred by executive scandals that would haunt his legacy for decades. The Gold Corner Conspiracy of 1869 involved railroad tycoons Jay Gould and Jim Fisk, who conspired to corner the gold market in New York. They controlled the Erie Railroad, and a high gold price would allow foreign agriculture buyers to purchase exported crops, shipped east over the Erie's routes. Boutwell's policy of selling gold from the Treasury biweekly, however, kept gold artificially low. Unable to corrupt Boutwell, the schemers built a relationship with Grant's brother-in-law, Abel Corbin, and gained access to Grant. Gould bribed Assistant Treasurer Daniel Butterfield to gain inside information into the Treasury. In July, Grant reduced the sale of Treasury gold to $2,000,000 per month. Fisk told Grant his gold selling policy would destroy the nation. By September, Grant, who was naive regarding finance, was convinced a low gold price would help farmers, and the sale of gold for September was not decreased. On the 24th of September 1869, known as Black Friday, Grant ordered Boutwell to sell, whereupon Boutwell wired Butterfield to sell $4,000,000 in gold. The bull market at Gould's Gold Room collapsed, the price plummeted from 160 to 35, a bear market panic ensued, Gould and Fisk fled, and economic damages lasted months. The Panic of 1873 led to the Long Depression, which contributed to the Democrats winning the House majority in 1874. Grant's response to the economic crisis was ineffective in halting the Long Depression. The Credit Mobilier scandal involved the Union Pacific Railroad, and the Whiskey Ring scandal involved federal officials who conspired to defraud the government of tax revenue. Grant's Secretary of War, William W. Belknap, was impeached for taking bribes, and Grant's Secretary of the Navy, George M. Robeson, was involved in the Navy Yard Scandal. These scandals tarnished Grant's reputation, and he was inundated by executive scandals during his second term. The Democrats won the House majority in 1874, and Grant's popularity declined. The Senate rejected his proposal to annex Santo Domingo, and the Alabama Claims against Britain were peacefully resolved, but the Senate rejected his proposal to annex Santo Domingo. Grant's foreign policy was limited, and he relied heavily on his talented Secretary of State Hamilton Fish. The Treaty of Washington settled the Alabama Claims, and the settlement of $15,500,000 resolved troubled Anglo-American issues and turned Britain into America's strongest ally. The Korean expedition of 1871 was sent to open up trade with a country which had a policy that excluded trading with foreign powers, and to learn the fate of U.S. merchant ship SS General Sherman, which had disappeared up the Taedong River in 1866. Grant dispatched a land and naval force consisting of five warships and over 1,200 men, under Admiral John Rodgers.
