It was galling me earlier when my co-workers started talking about drinking Coronas for Cinco De Mayo to celebrate 'Mexican Independence Day ( Sept 16th)' which it is not. So in the interest of an enlightened TB community, here are the facts about the temporary victory of the Mexican militia under General Zaragosa against France's colonial adventure under Emporer Napolean III. Cinco De Mayo link. Interesting to note the following, in particular 'Commercial interests in the United States and Mexico have also been successful in promoting the holiday, with products and services focused on Mexican food, beverages and festivities, with music playing a more visible role as well. Several cities throughout the U.S. hold parades and concerts during the week following up to May 5th, so that Cinco de Mayo is becoming a bigger holiday north of the border than to the south, and adopted into the holiday calendar of more and more people every year. Emphasis is mine. The beer companies promote this holiday in the US to sell more beer, if you haven't noticed. I propose we make the 18th of June a holiday as well so I can drink more Newcastle ale! All hail the Duke of Wellington!
