Lieutenant Rankin Dilworth died 4 days later on September 27, 1846.

The Museum of South Texas Historyís Sunday Speaker Series presents Dr. Joseph E. Chance and his book, The March to Monterrey on Sunday, March 29, from 2:00pm-4:00pm. The March to Monterrey is the final installment of the Joe Chance Mexican War Trilogy at the Museum.

Never before published, Dr. Chance has carefully edited & annotated the private diary of Lieutenant Rankin Dilworth to produce The March to Monterrey. The result is a first-hand account of the trials and tribulations experienced by Lieutenant Dilworth and his regiment during the Mexican-American War.

The March to Monterrey documents the sights and sounds of the Mexican-American War through the eyes of Lieutenant Rankin Dilworth. Recently graduated from the United States Military Academy, Lieutenant Dilworth chronicles his journey down the Mississippi River to New Orleans, his travel by Gulf steamer to Brazos Santiago, and the long hot trek overland to Monterrey. As a member of General Zachary Taylorís Army, Dilworth fought in Monterrey until he was mortally wounded on September 23, 1846. This is where his diary ends. Dilworth died on September 27, 1846.
