In 1993, with funding provided by the Summerlee Foundation of Dallas, The Descendants of Mexican War Veterans began a formal survey of historic sites of the U.S.-Mexican War. Literary research, for the purpose of preparing an historical narrative for each site, was also conducted. The initial survey was carried out between September 1, 1993 and February 28, 1994.
Unlike a Mexican War battlefield survey presently being conducted by the U.S. National Park Service, the DMWV survey list includes encampments, supply depots, and forts - as well as battlefields.
It was intended from the start that the results of the survey would be published for the further purpose of raising funds with which to preserve, protect and/or enhance the sites being studied. To date, one volume, Historic Sites of the Mexican War in the United States, Part One: Texas, has been published. Profits from sales of this book helped to pay for the Old Fort Brown Memorial Flagpole, erected in April 1996.
