A Short, Offhand, Killing Affair—Soldiers and Social Conflict During the Mexican-American War

Drawing on wartime diaries and letters not previously examined by scholars, Foos shows that the experience of soldiers in the war differed radically from the positive, patriotic image trumpeted by political and military leaders seeking recruits for a volunteer army. Promised access to land, economic opportunity, and political equality, the enlistees instead found themselves subjected to unusually harsh discipline and harrowing battle conditions. As a result, some soldiers adapted the rhetoric of Manifest Destiny to their own purposes, taking for themselves what had been promised, often by looting the Mexican countryside or committing racial and sexual atrocities. Others deserted the army to fight for the enemy or seek employment in the West. These acts, Foos argues, along with the government's tacit acceptance of them, translated into a more violent, damaging variety of Manifest Destiny.
