Everywhere I read on the internet about May 5, 1862 in Puebla, Puebla, Mexico, they say that Americans should celebrate the holiday as well. It says the its very significant for Mexicans and Americans. Even though the battle was fought in mexico. I guess if you look at when the americans through out the british in the century prior.
Anyway, I guess its up to every one if they want to celebrate it or not. It seems as if lot’s of people are celebrating not just mexicans.
If you need reading material on it then you should look at this wikipedia site.
anyway, updating later on,
