There’s certainly a reason that the United States Marine Corps officers’ sword is patterned after the “Mameluke Saber” ...
The first one was presented to William Eaton by the Bey of Tripoli’s brother. Eaton was sent to Egypt with a small force of Marines to recruit a force to overthrow the Bey and install his brother in his place. Eaton led a force of US Marines, Greek mercenaries and Arab tribesmen across the border and captured the city of Derna. While there, Eaton’s force was double crossed by Jefferson who concluded a deal with the Bey, and left the Bey’s brother in the lurch. Eaton and his Marines had to be figuratively dragged off the beach by the Navy, as their other comrades where left to their fate. Eaton hated Jefferson for the rest of his life for this.
