How did a Sephardic Jew save the American Revolution?

Haym Salomon, a Sephardic Jew from Poland, is the largely unknown benefactor of the American Revolution. Immigrating to the American colonies just before the outbreak of the War of Independence, Salomon used his unique business and language talents to outwit British forces several times, and used his brokerage business to fund the final Battle of Yorktown. But the American Revolution was not the only cause he believed in; Salomon also left behind a legacy of building and strengthening the Jewish community in the newly formed United States of America
