Where the Regiment Was Scattered During the Mexican War

A lack of Mexican War records has vexed historians as they’ve tried to pin down where the ten companies of the 1st Dragoons operated between 1845 and 1848. It wasn’t until 1851, three years after the treaty with Mexico, that the army comprehensively recorded where the units were during the war.

Except for five companies assigned to the Army of the West, the rest lay all over the map, in groups formed from between one and three companies, from present-day Oklahoma and south into the Valley of Mexico. This complicated efforts to track troop movement and personnel from the regimental headquarters at Ft. Leavenworth, Missouri Territory.

Below is a useful summary of where the regiment’s ten companies served during the years 1845-1848. I’ve taken these from annual returns of each year (from the National Archives’ NARA M7742).

  1. What an awesome website you have here.
    You’ve done a yeoman’s job collecting, archiving and publishing this.
    I love the original flavor you’ve kept.
    I came across it looking for info about Dragoons and Col Kearney who is oft mentioned in Francis Parkman Jr.’s ‘The Oregon Trail.’
    I’ve been listening to the Librivox.org rendition and reading it along, too.
    Again, Good Job!


    1. JE,

      Thanks for the kind words. I’m using the blog as closet to store goods I’ve been collecting for the past five years and, with lots more stuff, shall be including in a regimental history.

      Minor curiosity: Kearney, Nebraska and Fort Kearny are spelled the way you spell it, but the proper spelling for Steven’s name is Kearny.
