I've read that the Spanish didn't use guns very often during the Aztec conquest and that they were forced to retreat in their attempt to attack Tenochtitlan, so I was wondering if there are any examples of Aztec weapons being effective during a battle against the Spanish. Are there records of their clubs, lances, bows and arrows, etc. being effective? The most that I've been able to find is that one weapon called the Mācuahuitl could decapitate a horse with one blow. Did the Spanish make any references to these weapons in their diaries/books?
