September 14 is the anniversary of The Occupation of Mexico City in 1847. The imperial troops had spent the last few days blasting the city with artillery, and were at least free to do what they wanted in the city.

The suffering families remained within their houses constantly in dread that the Americans would come to break open their homes, and perpetrate the most shameful crimes upon their persons. . . . Dead bodies lay scattered through the streets; many soldiers of the cavalry ran through the city, striking their swords against the walls, violating the doors of private houses and the stores of merchants, taking from the one the most precious goods and from the other eatables scarce among the inhabitants; for the fear of going forth to purchase them, at the very few shops open during the day, induced the quiet people to remain without food.

Things only got worse from here. The American troops, offended as always by populations that attempt to resist them, responded with all the crime that they wanted (which was a LOT). Nobody was punished. The US Marines boast about it in their official song to this day. Which is actually strikingly honest about the US' true values. Human rights will always take a backseat to their imperialist desires. They honour the time that they raped and pillaged Mexico City.
