Alright; where are you getting your info on this conflict, or where can I read more? I continually get the revised we kicked butt version instead of the truth.
The mexicans along with native American indians and a herd of cattle did kick the butts of the French on may 5, but the French sent more troops and kicked the Juarez out of Mexico City and installed Maximilian.
