Finding Mexican War 1846-1848 Military Records

The U.S. Mexican War (also known as the Mexican-American War and US Mexican War) began due to the U.S. annexation of Texas. War was declared on May 13, 1846, and ended on February 2, 1848, with the Treaty of Guadalupe Hildalgo. During the War, there were several significant battles, the most famous being “The Alamo.” The treaty fixed the Rio Grand River as the boundary of Texas. It required Mexico to cede to the United States all the territory that makes up the states of California, Arizona, New Mexico, Nevada, Utah, and parts of Colorado and Wyoming in return for $15 million. There were 35,000 U.S. Army soldiers and 73,000 volunteers who fought in the War. Most volunteers came from Southern states (e.g., Louisiana, Missouri, Tennessee, and Texas.) U.S. soldiers served in the War with an age range 15-50 years old.

Finding Evidence of Individuals Who Served in the U.S. Military

The following are a few tips I have used to define if an individual might have served in the military during this period.

  • List all the wars that existed during each individual’s lifetime and their age during the War? As a rule of thumb, the age range for soldiers during a war period is 16-60.
  • Look for clues that might be found on gravestones, family papers, obituaries, and biographies.
  • Look where the person lived. Does the individual live on what is referred to as the frontier (westernmost land) of the United States in the early 1800′? This might indicate that he received bounty lands.
  •  Search indexes for military land patents and other military records. If you don’t find a person in one index, try another. It is not uncommon to have individuals who were veterans of multiple wars.
  • Identify if the veteran belongs to the regular Army, state militia or another unit. Were they in the Army, Navy or Marines? Answers to these questions will guide you to where to find the records.

Search for the Following Records

Pension records

Pension records usually include the veterans’ rank, residence, age or date of birth, and time of service. The widow’s application may include her place of residence, her maiden name, the date and place of marriage, the date and lace of her husband’s death, and the names of children under 16. A child’s or heir’s file contains information about the veteran and the widow and child’s place of residence, date of birth, and date and place of the widow’s death. If your ancestor did not receive a pension, see if his pension request was denied. Pension applications, pension-payment records and many other military records for all U.S. forces 1775–1916 are held at the NARA in Washington, D.C.

Bounty land applications and warrants

Congress granted bounty-land warrants for service in the Mexican War in 1847. Veterans could apply for bounty land, and they were entitled to 160. Copies of the bounty land files will show where the veteran settled after the War, and provide a physical description, age, and place of birth. The actual bounty land warrants have less information. Digitized land patents may be found on the Bureau of Land Management.

Service records

The service records consist of compiled (CMSRs) formed in the 1890s from various sources (e.g., muster rolls, descriptive rolls, payrolls.) The service records can show the soldier’s name, rank, regimental unit (usually showing the last name of the regimental commander), the company commander’s name, dates of service and pay, whether the soldier was a substitute, date of discharge, and sometimes, distance to the soldier’s home from the place of discharge, date of death, if applicable, and periods of sickness. Microfilm records exist for soldiers serving from Arkansas, Mississippi, Pennsylvania, Tennessee, Texas, and Mormon volunteers (Mormon Battalion).
