Battle of Churubusco
After a community meeting, the residents selected Churubusco for the new post office, named after the site of the 1847 Battle of Churubusco, in Mexico during the Mexican–American War. At the time, after the suggestion of local school teacher Eliza Rich, the townsfolk thought it was as patriotic a name as Union and Franklin, since the United States won a large victory there. More importantly, they were certain no other Indiana town would already have chosen such a unique name. The Churubusco post office has been in operation since 1848.
