Book excerpt: This unprecedented compilation provides the fullest examination anywhere available of the crucial social-political and strategic and policy-level issues of American military history between the Revolution and the Civil War: civil-military relations and the military‘s place in American society and politics; westward expansion and the diverse peacetime missions assigned the military, especially constabulary missions and operations; force structure, mobilization and the formation of military strategy in support of national objectives; and military preparedness, administration, reform and professionalization. The introduction links all of these issues, pointing to the increasing scale, scope and organization and the growing dominance of national forces in American military institutions and operations during this important period.
