During the Revolutionary War, Jackson's eldest brother, Hugh, died from heat exhaustion after the Battle of Stono Ferry on June 20, 1779. Anti-British sentiment intensified following the brutal Waxhaws Massacre on May 29, 1780. He paid for provisions for the men out of his own pocket. The soldiers began referring to their commander as 'Hickory' because of his toughness, and Jackson became known as 'Old Hickory.' The army arrived in Nashville within about a month. Jackson's actions earned him respect and praise from the people of Tennessee.
