Francisco Pizarro won the battle of Cajamarca with a troop of 180 bedraggled men fighting in a climate alien to their bodies against 80,000 fierce, battle-tested Incas fresh from their massive victories in a civil war.
Your quote is in no way related to your question given that this population reduction isn’t “troop losses.” It’s refugees. Mostly women and children. The overwhelming majority of them want to come back, as real refugees (as opposed to migrants) tend to do. What did you think, that these are all men who died in battle or something?
Let’s be cool, collected, focused and determined like Pizarro, and we’ll all win at our individual Cajamarca.
