Medieval Pole Arms by Gary Gygax (The Strategic Review V1 N2, TSR, Summer 1975)  There were only 7 issues of the Review before The Dragon replaced it, but it introduced a number of monsters and classes to OD&D and clarified some of the rules.  Some of AD&D’s odd flaws suggest Gary may have assumed everyone had read all of these articles.  Nowhere in the 1977 Player’s Handbook did he explain that a Lucern hammer is a sharp piercing weapon, letting a generation of players assume it was a blunt weapon for clerics.
