i disagree. the spaniards all had the same amount of cruelty give or take. pedro de alvardo was slightly worse in mexico imo, and francisco pizzaro slightly worse in peru. either way they all did the same throughout the americas - used greyhounds to rip native children apart, burned native leaders alive, dismembered natives with swords, and so on.
the genocide in mexico was tragic imo. ''history'' would have us believe the aztec emperor was killed with stones by his own people, but further reading shows the spaniards stabbed him 5 times, when it was made clear his powers became useless. each of the mexican leaders they had chained together got stabbed, but the one advocating all out war against the spanish from the beginning was stabbed 47 times - even in chains he fought the hardest.
after killing hundreds on their escape from mexico that night, and after smallpox had taken out thousands of aztecs, and after thousands of neighboring natives sided with the spanish, and after cutting off their capitals water supply and besieging them from land and water, it still took an entire summer to defeat the aztecs. ''defeat'' of course equaled the complete destruction of their city and near destruction of the entire population. cortes detailed how they incinerated the king's zoo, how they slaughtered 40,000 woman and children when there was no men left to defend them.
i recommend Las Casas Destruction of the Indies also, and American Holocaust.
