This historical study offers "a new understanding of the human cost of the [Republic of Texas's] vainglorious attempt to attack Mexico" (Western Historical Quarterly). The Somervell and Mier Expeditions of 1842, culminating in the famous "black bean episode" in which Texas prisoners drew white or black beans to determine who would be executed by their Mexican captors, still capture the public imagination in Texas. But were the Texans really martyrs in a glorious cause, or undisciplined soldiers defying their own government? How did the Mier Expedition affect the border disputes between the Texas Republic and Mexico? What role did Texas President Sam Houston play? In Soldiers of Misfortune, Sam W. Haynes addresses this and other important historical questions. Expertly researched yet accessible and engaging, Haynes's narrative includes many dramatic excerpts from the diaries and letters of expedition participants.
