Mexican War Room

The Mexican War was declared on May 13, 1846. It ended on February 2, 1848 with the signing of the Treaty of Guadalupe Hidalgo. Approximately 7,000 Ohio men fought for the United States. They formed five infantry regiments, fifteen independent companies of infantry, five companies of the U.S. Infantry and one company of U.S. Mounted Riflemen. Immediately after they were organized, units were sent to Camp Washington near Cincinnati, where they were mustered into service.

The Mexican War Room contains images of three flags and one unidentified flag remnant. The identified flags, all national colors, were carried by the 1st, 2nd and 4th Ohio Volunteer Infantry regiments. Of particular note is the flag of the 1st O.V.I., which has an unusual design on its canton and was carried by Captain Hamilton of Company D at the Battle of Monterey.

Flags in the Mexican War Room are displayed in order by regiment number:
