Presley O'Bannon was a first lieutenant in the United States Marine Corps, famous for his exploits in the First Barbary War (1801–1805). In recognition of his bravery, he was presented a sword for his part in attempting to restore Prince Hamet Karamanli to his throne as the Bey of Tripoli. This sword became the model for the Mameluke Sword, adopted in 1825 for Marine Corps officers, which is part of the formal uniform today.
