We're not getting all the facts

Well so far Restall's Seven Myths of the Spanish Conquest has been quite an intriguing book. He proves that as historians many times we have a distorted picture of what really happened in the past. In this case its the Spanish conquest of Latin America. Which conquest seems humorous right about now after reading the myth of completion. These conquistadors were really entrepreneurs trying to convince the crown that they were having success. It explains why these "conquistadors" sought for these precious metals. It seems that it was really their only source of credibility. They were perpetually pressured to prove themselves. Which is disappointing when you come upon sources and its evident that they were written for a political purpose. Yet what's discouraging is that we rely on these accounts to somewhat figure out what was going on. For example the Franciscan, Bernandino de Sahagun who wrote a "pean of praise to Hernan Cortez" its clear he wasn't being truthful especially having originally written a version on the perspective of the natives. This situation is one of the thousands of reasons why we have such a inflated view of Cortez today. He was given more credit then he deserved. Obviously Cortez is not the only one, Columbus is most certainly on the same page as well. For years we grew up believing that his voyage was often disregarded because he was the only one that believed the Earth was round. Which was not the case most likely they thought he was just a moron. They didn't believe at least in the Salamanca meeting that his approximations on the distance between Spain and Asia were accurate. The fact that most schools are still teaching students that they thought the earth was flat is ludicrous. Its disheartening because you wonder if History can be trusted. For decades historians have put pieces together like detectives and have tried to interpret events of the past but theres the possibility that we could be wrong. I mean there are so many details that are often left out or discredited. For example the fact that Africans also had a part in the Spanish conquest like Juan Valiente and Juan Garrido. Africans fought alongside the spaniards and there's hardly any mention of it. Its irritating to see this because we're left to believing in fairytales that these immense empires were dismantled in the hands of only a few brave spanish soldiers. Its misleading because there were also thousands of native allies that contributed. Also these so called "soldiers" were really just a bunch of spanish men in search of fame,fortune, etc. Im looking forward to finishing this book and so far my perspective of the "conquest" is without doubt changing.
