The Code Duello, covering the practice of dueling and points of honor, was drawn up and settled at Clonmel Summer Assizes, 1777, by gentlemen-delegates of Tipperary, Galway, Sligo, Mayo and Roscommon, and prescribed for general adoption throughout Ireland. The Code was generally also followed in England and on the Continent with some slight variations. In America, the principal rules were followed, although occasionally there were some glaring deviations.
Rule 15. Challenges are never to be delivered at night, unless the party to be challenged intend leaving the place of offense before morning; for it is desirable to avoid all hot-headed proceedings.
