Delope (French for "throwing away") is the practice of deliberately wasting one's first shot in a pistol duel, an attempt to abort the conflict. The Irish code duello forbids the practice.
Notable uses
Alexander Hamilton, a 19th-century American politician, is thought to have attempted to delope during his infamous duel on July 11, 1804, with Aaron Burr, the Vice President of the United States. Rather than firing into the ground (as was customary in a delope), Hamilton intentionally fired into the air over Burr's head. Burr, perhaps misunderstanding his opponent's intent, fired at Hamilton and mortally wounded him. Burr and Hamilton's mutual animosity was such that it is not out of the question that Burr understood what Hamilton was doing but intentionally shot to kill or at least draw blood. Other historians have proposed that Burr shot first and the wounded Hamilton reflexively pulled the trigger, which would not be an instance of deloping. Ron Chernow's 2004 biography Alexander Hamilton gives that version. According to Chernow's account, the shots were all but simultaneous, with Burr's coming first according to one of the two witnesses (the other witness claimed that Hamilton had fired first and that Burr waited several seconds for the smoke to clear before he returned fire). Chernow noted that Hamilton, in a note left behind in case he died, claimed to have intended to throw away his first shot, which Burr would later call "contemptible, if true". Regardless of its accuracy, Burr certainly had no way of knowing. Hamilton's eldest son, Philip, had died in a duel against George Eacker three years earlier. According to legend, the elder Hamilton had advised his son to delope as well.[1]
