US Mexican War Soldiers & Sailors Database

On May 8, 1846, U.S. and Mexican soldiers met on the field of battle. For two years, over 150,000 soldiers fought a war that forever changed these young countries. All sacrificed part, if not all, of their life. Some became famous while others faded into the annals of history. Explore this database to discover if their story is part of your history.

How to Read

Misspellings and errors are common in transcribed documents. Alternate names and/or misspellings are recorded as initially documented. Alternate names or spellings will show as—also known as (aka). Information not recorded on a muster roll or register of enlistment is shown as Unknown. With your help, we can preserve history and turn unknowns into knowns.
